Bypass Valve pressure specs (Mann for VW/Audi) - Bob Is

Thanks, Filter guy. I was asking because many of us Audi V6 owners use the larger 940/25 filter, and I was wondering if its larger capacity came along with an inappropriate bypass valve pressure setting or an inferior filter medium. ...<< more>>

Automatic Compressor Discharge Bypass Expansion Valve

The Discharge-bypass valve can be used as automatic expansion valve under fixed pressure to maintain the fixed evaporation pressure (temperature). The Discharge-bypass valve is capable to prevent the refrigerating compressor set from extract pressure decreasing lower than the minimum value. ...<< more>>

The bypass valve is triggered by a spring-loaded mechanism that opens when fluid pressure becomes too high or too low, Winter says. As long as the pressure is the same on both the inlet and the outlet side of the spring, the switch remains closed. ...<< more>>

Powermate 150 psi Pressure Relief Valve-136-0005RP - The

The pressure relief valve releases when too much pressure has built up in the air compressor tank. The pressure relief valve is a safety must when operating an air compressor. A working pressure relief valve is necessary when operating a compressor ...<< more>>

Relief valve - Wikipedia

A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire. The pressure is relieved by allowing the pressurised fluid to flow from an auxiliary passage out of the system. ...<< more>>
