Parker 0R50B Quick-exhaust Valve 200 Psi Aluminum

Product Description

The PARKER 0R50B is a quick-exhaust valve designed for pneumatic systems requiring rapid cylinder or actuator exhaust. When inlet pressure drops, the valve redirects airflow directly out the exhaust port rather than back through the supply line, dramatically reducing exhaust time and increasing actuator cycle speed. The aluminum body keeps weight low while handling pressures up to 200 psi. Both the inlet and exhaust ports measure 0.5 inches, making plumbing straightforward in standard pneumatic circuits. This valve is installed by industrial maintenance technicians, automation specialists, and HVAC controls contractors working with pneumatic actuator systems.

The 0R50B is suited for applications where fast actuator response is critical, including pneumatic cylinder drives, control valve actuators, and automated pneumatic tooling. Its wide operating temperature range of 0 degrees F to 500 degrees F makes it viable in both cold-storage environments and high-temperature industrial installations. It is typically installed close to the actuator to maximize exhaust response benefit. The compact aluminum body fits in tight panel or inline mounting configurations common in commercial and light industrial pneumatic control panels.

Key Features

• Maximum working pressure of 200 psi (13.8 bar) for robust pneumatic circuit compatibility
• Inlet and exhaust port size of 0.5 inches for direct inline installation
• Aluminum body construction for lightweight, corrosion-resistant performance
• Wide temperature range from 0 degrees F to 500 degrees F suits diverse operating environments
• Quick-exhaust function accelerates actuator cycling by bypassing the supply line on exhaust stroke

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard 0.5 inch ported pneumatic circuits requiring quick-exhaust valve function.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or industrial maintenance professional. Depressurize the entire pneumatic circuit and isolate the compressed air supply before removing or installing any valve. Mount the valve as close to the actuator as possible to achieve maximum exhaust speed benefit. Verify all port connections are leak-free with a soap solution or electronic leak detector before returning the system to service.
