WebJul 14, 2024 · Pilot valves are high-flow control valves for a system. The pressurized fluids mostly move the pilot-operated valves. When the set pressure is achieved, the valve opens and the pressure is released. The flow directing element of the valve changes when pressured fluid meets the valve piston.

A back pressure regulator is used to control the pressure of any fluid, gas, liquid or mixture in a system. Most pumping applications require back pressure to be maintained on the outlet of a pump, which is why back ... WebThis supply pressure pushes up on the control valve diaphragm working against the tension of the spring. This opens the valve and allows upstream pressure to move downstream. Next, downstream gas moves through the sense line protector. This device protects the pilot from over pressurization. normal cystic duct diameter
