Relief Valves

Crissair, Inc. has a long history in the aircraft industry, having provided precision products for almost every airframe manufacturer and major subcontractor. Our goal is to provide superb, high-quality components of every complexity level for hydraulic, fuel, and pneumatic systems. With more than 11,000 unique designs ranging from complete manifold assemblies to less complex valve assemblies, we are able to work closely with each of our clients to ensure project perfection from initial proposal through the final qualification.

Quality Relief Valves Suitable for all Aircraft Fluid Types

Our relief valves include:

  • Rosan style
  • Soft seat
  • Hard Seat
  • Drop-in
  • Thread-in
  • Cartridge
  • Inline
  • Filtered

Our relief valves are used for system functionality, system over-pressurization, and thermal expansion. Crissair designs and manufactures several types of relief valves, from high-pressure and high-flow system relief valves to direct acting low-pressure relief valves. Our valves are qualified for system pressures from 0.2 to over 6000 PSI using materials including stainless steel, aluminum, and titanium.

The world-class line of high-pressure system relief valves offers an amazingly stable flow curve with low pressure drops from crack to full flow, and very tight internal leakage rates at reseat and below. Crissair also offers zero-leak relief valves that employ soft seat materials. If you have a specific valve requirement, contact us; we can design our relief valves specifically to fit our customer’s needs.
