The FMS-G06 flow control valve is designed for industrial hydraulic systems that require controlled oil flow and adjustable actuator speed.

By controlling the amount of hydraulic oil passing through a circuit, the FMS-G06 can help regulate the operating speed of hydraulic cylinders and other actuators. Solenoid-operated FMS-type valves combine electrical switching with hydraulic flow adjustment, making them useful where machinery needs different flow conditions during different stages of operation. FMS-series documentation describes this type of valve as combining a bypass solenoid stage with a pressure-compensated flow-control section.

Its basic control concept can be understood as:

Electrical Command → FMS-G06 Valve → Controlled Hydraulic Flow → Actuator Speed

This makes the FMS-G06 suitable for machine tools, hydraulic power units, presses, production equipment, and other industrial hydraulic applications where simple and reliable speed regulation is required.

What Is an FMS-G06 Flow Control Valve?

The FMS family is commonly described as a solenoid-operated flow control or speed control valve. Product listings and hydraulic system documentation also identify the FMS-G06-02T as a solenoid-controlled hydraulic valve used in machine circuits.

Unlike a standard manual throttle valve, the FMS concept combines:

• Adjustable flow control
• Solenoid-operated switching
• Hydraulic speed regulation
• Electrical integration with machine controls

Depending on the specific configuration, the valve can be used to control flow through a selected hydraulic line and change machine speed according to an electrical command.

This is especially useful when a cylinder needs:

Fast Movement → Controlled Working Speed → Fast Return

rather than operating at one fixed speed throughout the entire machine cycle.

How Does the FMS-G06 Control Hydraulic Speed?

Hydraulic actuator speed depends strongly on oil flow.

A simplified relationship is:

Higher Flow → Faster Cylinder Movement

Lower Flow → Slower Cylinder Movement

The FMS-G06 controls flow by changing the effective passage through which hydraulic oil travels.

In FMS-type modular designs, a flow-control section regulates the adjusted flow while a solenoid-operated bypass section changes the flow condition according to the electrical state. Technical documentation for comparable FMS modular valves describes the combination of a bypass solenoid valve and a two-way pressure-compensated flow-control valve.

The control process can therefore be represented as:

PLC / Limit Switch / Relay

↓

Solenoid Signal

↓

FMS-G06

↓

Flow Condition Changes

↓

Cylinder Speed Changes

This allows a relatively simple electrical control signal to influence hydraulic operating speed.

Why Use a Solenoid-Operated Flow Control Valve?

A conventional manual flow-control valve is suitable when the machine operates continuously at one adjusted speed.

However, many industrial machines need more than one operating speed.

For example:

Rapid Approach → Slow Working Feed → Rapid Return

If a machine uses only one fixed throttle setting, it may be difficult to achieve both high productivity and controlled working movement.

A solenoid-operated flow-control valve helps combine:

Fast machine movement

with

Controlled low-speed movement

in the same hydraulic circuit.

This is one reason this type of valve is commonly used as a speed-control solution in industrial machinery.

FMS-G06-02T and Flow-Control Position

One commonly referenced model is:

FMS-G06-02T

Hydraulic equipment documentation identifies FMS-G06-02T-D24V in an industrial hydraulic circuit, while FMS-family catalogs use suffixes such as T, P, and A to identify the controlled flow path or circuit arrangement.

In FMS-type nomenclature, the T configuration is commonly associated with controlling flow toward the tank side or meter-out arrangement in related FMS designs.

However, when replacing an existing valve, the complete hydraulic symbol and full model should always be checked.

Do not select a replacement based only on:

FMS-G06

because different suffixes can represent different hydraulic functions.

Meter-In and Meter-Out Speed Control

Hydraulic speed control can generally be arranged in two common ways.

Meter-In Control

The valve restricts the oil entering the actuator.

Basic concept:

Pump → Flow Control Valve → Cylinder

This regulates how much oil enters the cylinder.

It can be suitable for some relatively stable resisting-load applications.

Meter-Out Control

The valve restricts oil leaving the actuator.

Basic concept:

Cylinder → Flow Control Valve → Tank

Meter-out control can help maintain better control where the load may tend to drive the actuator.

Comparable throttle-valve documentation confirms that hydraulic flow-control designs may be configured as either meter-in or meter-out depending on circuit requirements.

The correct arrangement should always follow the original hydraulic circuit.

Pressure Compensation Helps Improve Speed Stability

A simple throttle valve creates a restriction, but actuator speed may change when load pressure changes.

Pressure-compensated flow-control designs help reduce this effect.

Comparable FMS technical documentation describes the flow-control section as a two-way pressure-compensated flow control valve, designed to provide more stable controlled flow than a basic fixed restriction.

This is useful because industrial machine loads are not always constant.

For example:

• Cutting resistance may change
• Mold load may increase
• Cylinder force may vary
• Machine friction may change during motion

Better flow stability helps maintain more consistent actuator speed under changing working conditions.

Typical Applications of FMS-G06 Flow Control Valves

The FMS-G06 can be used in industrial hydraulic systems where electrically controlled speed changes are required.

Machine Tools

Hydraulic machine tools often require:

Fast Approach → Controlled Feed → Fast Return

The flow-control valve can slow the actuator during the machining or working stage while allowing faster movement during non-working travel.

Hydraulic Presses

Press equipment may need controlled movement as the cylinder approaches the workpiece.

Speed regulation can help reduce impact and improve movement stability.

Injection and Forming Machinery

Solenoid-operated speed-control valves are commonly used for multi-stage speed control in machinery such as injection and press equipment. Similar industrial valves are specifically marketed for close-mold, press, and CNC machine circuits.

Hydraulic Power Units

An FMS valve can be integrated into a power-unit circuit where different actuator speeds are required according to machine commands.

Automated Equipment

Electrical switching allows the valve to work together with:

• PLC outputs
• Limit switches
• Pressure switches
• Relays
• Machine sensors

This makes it suitable for simple automatic sequences.

Two-Stage Speed Control in Hydraulic Machinery

One of the most useful applications is two-stage speed control.

Consider a hydraulic cylinder that needs to move quickly at first, then slow down before contacting the workpiece.

The cycle may be:

Stage 1: Rapid Movement

High flow allows the cylinder to move quickly.

↓

Stage 2: Working Feed

The solenoid changes the hydraulic flow condition.

↓

Controlled Flow

Cylinder speed decreases.

↓

Working Operation

The machine completes its controlled movement.

This type of arrangement can improve both cycle time and process control.

Comparable solenoid-operated speed valves are specifically designed to provide two-stage cylinder speed control.

FMS-G06 vs Ordinary Throttle Valves

Both products can reduce hydraulic flow, but their control methods differ.

Feature	FMS-G06 Type	Ordinary Manual Throttle Valve
Flow Adjustment	Adjustable	Adjustable
Electrical Switching	Yes	No
Automatic Speed Change	Supported	Normally no
PLC Integration	Possible	Not direct
Two-Stage Operation	Suitable	Limited
Machine Automation	Better suited	Mainly manual setting
Typical Use	Industrial automatic circuits	Fixed-speed regulation

If a machine only needs one manually adjusted operating speed, a simple throttle valve may be sufficient.

If the machine needs the flow condition to change automatically during the production cycle, the solenoid-operated FMS design offers additional flexibility.

FMS-G06 Is Not a Proportional Flow Valve

Another important distinction is between:

Solenoid-operated flow control

and

Proportional flow control

The FMS-G06 uses solenoid switching to change the hydraulic operating condition.

It should not automatically be treated as a continuously variable proportional valve.

A proportional flow valve such as a 2FRE-type product can change flow continuously according to an electrical command.

The difference can be simplified as:

FMS-G06 → Electrically Switched Speed / Flow Control

Proportional Flow Valve → Continuously Variable Electrical Flow Control

For equipment that only requires fast/slow switching, an FMS-type valve can provide a simpler solution.

For continuously programmable speed control, a proportional valve may be more appropriate.

Coil Voltage Must Be Confirmed

Because the FMS-G06 includes solenoid control, electrical specifications are important.

Published FMS-GO listings show versions using common voltages such as:

• DC24V
• AC110V
• AC220V

and actual hydraulic-system documentation includes an FMS-G06-02T-D24V version.

Using the wrong coil voltage may cause:

• Failure to switch
• Weak solenoid force
• Excessive heating
• Coil damage
• Unstable machine operation

Therefore, voltage should always be confirmed from the original nameplate.

What Should Be Confirmed When Replacing an FMS-G06?

For a replacement project, the basic model alone is not enough.

We recommend confirming:

• Complete original model
• Hydraulic symbol
• Controlled flow path
• T / P / A configuration
• Required controlled flow
• System maximum flow
• Working pressure
• Coil voltage
• Electrical connector
• Thread or mounting configuration
• Existing adjustment setting
• Equipment application

If the original label is difficult to read, provide:

Overall Product Photo + Nameplate + Hydraulic Ports + Coil + Installation Position

This helps reduce mistakes when confirming the hydraulic function.

Common Problems in Flow-Control Circuits

If actuator speed becomes unstable, the flow valve may be one possible cause, but the complete system should be checked.

Cylinder Moves Too Slowly

Possible causes include:

• Flow setting too low
• Valve restriction
• Contamination
• Pump flow too low
• Filter blockage
• Incorrect solenoid state

Cylinder Speed Changes Under Load

Possible causes may include:

• Pressure-compensation problems
• Excessive load variation
• Internal leakage
• Worn flow-control components

Valve Does Not Switch Between Speeds

Check:

• Coil voltage
• Electrical signal
• Solenoid condition
• Valve contamination
• Internal spool movement

Hydraulic Oil Becomes Too Hot

Excessive throttling converts hydraulic power into heat.

Possible causes include:

• Flow restriction too severe
• Incorrect valve sizing
• Excessive system pressure
• Continuous throttling at high flow

Flow control should therefore be adjusted according to actual actuator requirements rather than simply restricting the valve as much as possible.

Oil Cleanliness Matters

Flow-control valves contain relatively small metering passages.

Contamination can affect:

• Metering accuracy
• Solenoid switching
• Compensator movement
• Flow stability
• Internal leakage

Maintenance should include checking:

• Hydraulic oil condition
• Filters
• Valve mounting surfaces
• Hydraulic lines
• Electrical connectors

Before installing a replacement FMS-G06, the surrounding hydraulic circuit should be cleaned if contamination is suspected.
