High Flow Rate Vacuum Relief Valve

Ideal for high flow rate vacuum pumps, the GZMS VCV101B Vacuum Relief Valve can handle the largest vacuum pumps we sell and restrict the amount of vacuum you are pulling to your chosen set point ranging from 5" to 20". This model utilizes 7/8-14 NF straight thread, seal washer and nut for installation in a .875 OD Valve Cover Hole. This same design is also available with 1/2 NPT thread, see VCV101A.

You can adjust the vacuum relief set point by screwing the top cap up and down the body. The adjustment is secured by the knurled knob at the bottom of the valve which locks the adjustment in place.
