The Z2FS10-30B Type Modular Restrictive Check Valve is a high-performance sandwich plate hydraulic flow control valve designed to restrict oil flow in one direction while allowing free flow in the opposite direction through an integrated check valve. Featuring a compact modular structure, the valve provides accurate actuator speed control, stable hydraulic performance, and flexible installation in hydraulic manifold systems. It is widely used in industrial hydraulic equipment, machine tools, hydraulic power units, and construction machinery.

Working Principle

The Z2FS10-30B modular restrictive check valve uses two symmetrically arranged throttle/check valve assemblies to control hydraulic oil flow. Hydraulic oil is throttled in one direction through the adjustable throttle spool to regulate actuator speed, while the built-in check valve allows free flow in the opposite direction with minimal resistance.

Depending on the installation orientation, the valve can be used for:

• Meter-in control
• Meter-out control
• Main flow limitation
• Pilot flow limitation

This design ensures stable motion control for hydraulic cylinders and hydraulic motors.

Applications

The Z2FS10-30B modular restrictive check valve is widely used in:

• Hydraulic power units
• Industrial automation systems
• Machine tools
• Construction machinery
• Hydraulic presses
• Injection molding machines
• Agricultural machinery
• Mobile hydraulic equipment
