Check & Relief Valves


     Lourdes check and relief valves have been designed for use in a wide variety of pneumatic, hydraulic and fuel applications from shipboard to space bound vehicles. They may be installed in any attitude and still maintain full flow and low pressure drop irrespective of most environmental conditions. Thin walled assembly is achieved through advanced electron beam welding technology - an added feature where weight becomes a critical factor.

     All valves are custom configured to meet even the most difficult design criteria.
