Check Valves
Brand: Valcor Engineering CorporationCheck valves prevent the backflow of process media in gas and liquid systems.
Our proprietary technology provides chatter free, stable performance and are well-suited for the extreme vibration, temperature, and cycle life requirements found in the most severe flight and ground-based operating conditions.
Their compact size and low weight allow these check valves to be used in the tightest space available.
Their all-welded construction eliminates external leakage.
They are available in single redundant valves assemblies.
Available soft goods include polymeric or elastomeric seats and seals.
