Description


POSU GR-1/8 Flow Control Regulating Valve - High-Quality PLC Industry Product

Advanced flow control functionality for reliable industrial applications.

The POSU GR-1/8 Flow Control Regulating Valve is a precision flow control solution designed for the PLC industry. It features robust construction, reliable operation, and compatibility with 1/8" NPT threads. Perfect for industrial automation and fluid control applications.

Engineer's Quick Brief

  • POSU GR-1/8 is a compact pneumatic flow control regulating valve designed for precise cylinder speed adjustment in industrial automation systems.
  • The valve integrates a needle throttling mechanism with push-to-connect pneumatic fittings, simplifying installation inside PLC-controlled pneumatic circuits.
  • Typical applications include air cylinder speed regulation, robotic motion damping, packaging equipment, and compact pneumatic manifolds.

SEO Introduction

The POSU GR-1/8 Flow Control Regulating Valve is a pneumatic speed controller used in compressed air systems requiring stable actuator motion and precise airflow adjustment. Designed for industrial automation environments, the GR-1/8 valve combines compact construction with reliable needle-type throttling performance for PLC-integrated pneumatic control systems.

This pneumatic regulating valve is commonly installed on air cylinders, pneumatic actuators, pick-and-place systems, robotic handling equipment, and packaging machinery where accurate cylinder speed tuning is critical for process stability and mechanical protection.

Troubleshooting & FAQ

Why does the pneumatic cylinder move too fast?

Excessive cylinder speed may result from insufficient throttling adjustment or incorrect installation direction. Verify whether the GR-1/8 valve is configured for proper meter-in or meter-out control.

What is the difference between meter-in and meter-out control?

Meter-in control restricts airflow entering the actuator, while meter-out control restricts exhaust airflow leaving the cylinder. Meter-out control is generally preferred for stable pneumatic motion.

Can the GR-1/8 valve be used with lubricated air?

Yes. The valve is compatible with both lubricated and non-lubricated compressed air systems.

Why is airflow adjustment unstable?

Unstable adjustment may occur due to pressure fluctuations, contaminated air supply, or excessive vibration affecting the adjustment screw.

What thread standard is used on the valve?

The valve uses a G1/8 pneumatic thread connection.
