Parker 0R37B Quick-exhaust Valve 3/8 in 200 Psi Aluminum

Product Description

The PARKER 0R37B is a quick-exhaust valve designed to accelerate the exhaust cycle of pneumatic actuators and cylinders by venting downstream air directly to atmosphere rather than routing it back through the supply line. The valve features 3/8-inch inlet and exhaust ports and an aluminum body rated for a maximum working pressure of 200 psi (13.8 bar). It handles operating temperatures from 0 degrees F to 500 degrees F, making it suitable for demanding industrial pneumatic systems. Licensed pneumatic and industrial maintenance technicians typically install this valve in compressed-air control circuits where faster actuator retraction or extension speed is required.

The PARKER 0R37B is suited for use in industrial compressed-air systems where rapid cylinder exhaust is a priority. Common applications include pneumatic press controls, clamping circuits, conveyor actuators, and other automated production equipment. The valve mounts inline at or near the actuator port to minimize the exhaust path length and maximize the speed improvement. It is appropriate for both light industrial and heavier-duty pneumatic circuits operating within its rated pressure and temperature range.

Key Features

• 3/8-inch inlet and exhaust port sizing for direct inline installation in standard pneumatic circuits
• Maximum working pressure of 200 psi (13.8 bar) to cover the majority of industrial compressed-air applications
• Wide operating temperature range from 0 degrees F to 500 degrees F for use in high-heat industrial environments
• Aluminum body construction provides a lightweight, corrosion-resistant housing
• Vents downstream air directly to atmosphere, significantly reducing actuator exhaust time
• Single-unit packaging with a minimum order quantity of one for easy replacement or retrofit use

Compatibility

Designed as an OEM-style replacement or inline addition for industrial pneumatic circuits requiring quick-exhaust function with 3/8-inch port connections and operating pressures up to 200 psi.

Installation Notes

Installation should be performed by a qualified pneumatic or industrial maintenance technician. Depressurize the pneumatic circuit completely and lock out the compressed-air supply before removing or installing any valve. Mount the quick-exhaust valve as close to the actuator port as possible to achieve the maximum speed benefit. Verify all fittings and thread sealant are compatible with aluminum bodies and the system operating pressure before returning the circuit to service.
