High Purity Gas Pressure Relief Valves Datasheets

Back Pressure Regulator -- BPR
from Beswick Engineering Co., Inc.

Beswick Miniature Back pressure Regulator (BPR) is a normally closed valve that senses and responds to changes in upstream pressure. Like a relief valve, it will open to vent excess pressures from the outlet port, when upstream pressure rises above the cracking pressure. Cracking pressure is... [See More]
