Pressure relief valve | |
These PVC valves have O-rings of Viton<reg>. Ideal for liquid applications. | |
Use for liquid applications with flow rates up to 15 GPM. For pressures from 40 to 150 psig. Valves have 1/2" NPT(F); orifice size is 5/16". | |
Useful for eliminating unwanted positive pressure build-up in glove boxes. Acrylic relief valve features 1/8" NPT stainless steel inlet and outlet ports. Exhausted air can be directed away from operators... | |
Valves with connections of 1/4" or 1/2" have a diaphragm made of Viton<reg> and withstand a maximum inlet pressure of 210 psig. All other valves have a PTFE shaft design... |
