Parker 0R25B Quick-exhaust Valve 200 Psi 1/4 Inch

Product Description

The PARKER 0R25B is a quick-exhaust valve designed to rapidly vent downstream pressure from pneumatic actuators and cylinders, reducing cycle time by bypassing the directional control valve on the exhaust stroke. Built with an aluminum body, it handles working pressures up to 200 psi and operates across a wide temperature range from 0 degrees F to 500 degrees F. Both the inlet and exhaust ports measure 1/4 inch, making it a straightforward fit in standard pneumatic circuits. Licensed pneumatic and industrial service technicians install this valve directly at or near the actuator to maximize exhaust speed.

This valve suits pneumatic control systems in commercial and industrial applications where fast actuator return strokes are required. Typical installations include pneumatic cylinders, air-driven clamps, and automation equipment where reducing back pressure on the exhaust side improves response time and throughput. The 1/4 inch port sizing fits commonly used tubing and fittings found in light to medium-duty industrial pneumatic circuits.

Key Features

• Maximum working pressure of 200 psi for use in standard industrial pneumatic systems
• Aluminum body provides a lightweight, corrosion-resistant construction
• 1/4 inch inlet and exhaust ports for direct integration with common pneumatic fittings
• Wide operating temperature range from 0 degrees F to 500 degrees F suits demanding environments
• Compact, single-package unit with a quantity of one per package

Compatibility

Designed as an OEM-style replacement or new-installation quick-exhaust valve for industrial pneumatic systems utilizing 1/4 inch port connections and operating within 200 psi working pressure limits.

Installation Notes

Quick-exhaust valves are installed by qualified pneumatic or industrial maintenance technicians. Depressurize the pneumatic circuit fully before removing or installing any valve components. Mount the valve as close to the actuator as possible to achieve maximum exhaust speed benefit. Verify all port thread types and sizes match existing fittings before final installation.
