Product catalog summary

Description and Features
The relief valves by Valcor Aerospace are designed for use in pneumatic or hydraulic systems to prevent damage from excessive pressure. They are particularly useful in scenarios where a failure or partial failure of another component could lead to pressure build-up, such as leakage past a pressure regulator seat or high temperature exposure in a closed system. Key features include adjustable relief pressure, suitability for both hydraulic and pneumatic applications, capability of handling high flows (up to 10 gpm) and high pressures (approximately 3300 PSI), and a lightweight design (~0.25 lbs).

Functionality
These valves vent excessive pressure to prevent damage to system components. They automatically reseat once the pressure returns to a safe level, ensuring minimal loss of system pressure.

Valcor Aerospace DESCRIPTION Valcor’s relief valves vent excessive pressure in pneumatic and hydraulic systems and components. the valves eliminate the possibility of part damage due to excessive pressure. the valves reseat as soon as the pressure decays to a safe level, and prevent further loss of system pressure. application the valves are used in any pneumatic or hydraulic system or component that could be exposed to excessive pressure by virtue of a failure, or partial failure, of another item. Examples include: the outlet side of a pressure regulator which may experience excessive pressure from leakage past the regulator seat, and excessive pressure build up in a closed system due to high temperature exposure. features • Adjustable relief pressure • Hydraulic and pneumatic applications • capable of high flows (10 gpm) • capable of high pressures (~3300 pSI) • Designed for lightweight, yet high strength applications (~0.25 lbs) © 2018 valcor ENGINEERING coRpoRATIQN pH:973-467-8400 Fx:973-467-9592 www.VALcQR.coM
