New high-speed exhaust valves

摘要

Activate oil, gas, petrochemical, and chemical operations with these new HIPEX valves.The 1/2, 1, and 2-in. normally closed directional control designshave a venting flow rate proportional to differential pressure between the inlet and pilot signal pressures. They are specifically designed for both modulating and "on-off" pilot pressure signals.When pilot pressure signal is equal to or above main valve inlet pressure, HIPEX's exhaust port remains closed. The control valves deliver partial close testing as well as pressure relief function.
