Protect the Detectors in Analytical Instruments from the Abnormal Pressure of Chemicals and Samples A diaphragm-type relief valve capable of handling several media like strong acids and strong alkalis because of the highly inert wetted materials such as PTFE ,PPS etc. The valve opens and the media flows to the secondary port when the primary pressure exceeds the relief pressure, preventing the pressure in the flow channel from rising further. Low cost with no pressure sensor required. Further cost reduction is possible after using molded parts. (Custom design is possible) Installs directly on the piping system (flow-through structure), which eliminates dead volumes created by branch piping to relieve pressure.
