The FEP-175-CH Pilot is a reversible pressure control pilot (seat & nozzle design) that is used in conjunction with Flexflo® Regulators to provide pressure control. The FEP-175-CH is typically utilized for high performance pressure control applications such as power plants. Applications include: pressure reduction, monitor regulators, backpressure control, and relief valves. The FEP features a friction-free design, sensitive sensing diaphragm, high sensitivity and minimal droop. Additionally, note that the FEP-175-Ch Pilot is a submersible design that is ideally suited for vault applications that fill with water.
