It operates on an air pressure set 25 psi bias. Model Variations The basic 4-inch Pressure Control Valve has an aluminum alloy body, flange and piston. Leading Particulars (continued) Operating Times Opening adjustable from 10 to 50 seconds initially set to 25 seconds Closing Closes when reference pressure is released (deadman) in 0.8 second minimum or when aircraft valve closes (surge control) in 0.75 second from start of aircraft valve closure Closing Time (Mod J) The surge control is ineffective and the closing time is adjustable from 1.0 to 15 seconds initially set to 2.5 seconds 4.

Leading Particulars Service Automotive and Aviation Fuels Mainstream Pressure Inlet Pressure up to 200 psi Outlet Pressure controllable from 15 to 75 psi Bias Pressure 25 psi (except Mod A, which is 16 psi) Pressure Drop 3.5 psi at 600 gpm Table 1. Leading Particulars (Refer to Table 1)Ĥ Table 1. Principles of Operation Refer to Figure Leading Particulars (Refer to Table 1) 4. This feature is available on all except the F370J variation.
Aircraft Valve Response In this mode, a downstream pressure increase caused by closure of the aircraft valve causes the F370 to close, thus preventing excessive surge build-up. Deadman Control In deadman mode, the release of the reference pressure to the servo causes the valve to automatically close. The difference between the reference and control pressures is termed "bias". This reference pressure is normally somewhat higher than the desired control pressure. An air pressure source or a regulated fuel pressure source must be provided to effect control. Pressure Control In this mode the valve operates on the basis of a fuel or air reference pressure. Description DESCRIPTION AND OPERATION The 4-Inch Pressure Control Valve (valve) provides three operating modes for the control of fluid flow in a pressure control system.
