Relief Valves
RelVal
We offer a wide range of relief valves for use on aircraft and spacecraft to prevent overpressure damage to critical systems. These components are designed as a poppet-style relief valve to provide overpressure protection where system anomalies such as over temperature or upstream component failure are a concern.
Our family of relief valves can be used in applications for gases such as nitrogen, oxygen or helium, with qualified configurations also available for liquids such as sea water, hydraulic fluids, and petroleum fuels.
Other features of our relief valves include...
- Aerospace qualified in launch and flight applications
- Bubble tight sealing up to cracking pressure
- Versions with cracking pressures up to 3,500 psig [242 bar]
- Constructed of aluminum, stainless steel & FKM elastomer
- Porting, manifold, and mounting flexibility
- Specialized custom configurations also available
We are always willing to apply our design heritage to engineer a configuration of this valve to meet your specific application requirements. For further information and specifications on our proven relief valve products, download our data sheet. Then contact South Bend Controls.
