The Inter Stage 3 – 4 Valve (Part #52840217) is a direct replacement part for Edwards dry vacuum pumps. This small valve, made of high-quality plastic , is used in the “interstage” purge system. It specifically controls the flow of purge gas between the 3rd and 4th stages of the pumping mechanism . This helps protect the pump when handling harsh or dangerous gases . If this valve fails, your pump will not purge correctly.

Valve, Inter Stage 3 - 4, Edwards, Part# 52840217
On pumps with four or more stages, the pressure changes dramatically between stage 3 and stage 4. This specific valve (3/4) has a very specific job: it controls the purge gas .
Purge gas is usually nitrogen or clean air. The pump uses this gas for two main reasons:
To Protect the Bearings: It stops dangerous process gases from getting into the pump’s oil and bearings .
To Help the Vacuum: It helps the pump run efficiently even at high inlet pressures .
Without this valve, the purge gas flow would be wrong, leading to pump failure.
