Aerospace Check Valves

Design Features and Benefits
Extensive material (body and seal) options
Low cracking pressures
Redundant (series) valve assemblies
Numerous sizes and flow rates
Chatter free designs


Valcor Check Valves provide protection against reverse flow with minimal effect on the system (low pressure drop and low chatter). Valcor check valves are available in redundant valve assemblies or single valve devices. Our valves use either polymeric or elastomeric seats and seals.


Valcor check valves have applications in spacecraft and launch vehicle propulsion propellant control for reaction control systems (RCS) and Attitude Control Systems (ACS) where high vibration, large temperature extremes and corrosive fluids are present.
