Model LFCP15
Pressure Reducing Pilot
Size:
3⁄8
" NPT
The Model LFCP-15 is a direct acting, diaphragm actuated Pilot
that automatically reduces a higher upstream (inlet) pressure to a
constant downstream (outlet) pressure. It is normally held open by
the force of the adjustable spring setting above the diaphragm.
The Pilot modulates towards a closed position when outlet pres-
sure exceeds the spring setpoint, lowering the delivery pressure.
It modulates towards an open position when the outlet pressure
falls below the spring setpoint, increasing the delivery pressure.
When a Model LFCP-15 is installed in the piping circuit of an
Automatic Control Valve, its throttling action causes the Main
Valve to throttle open or closed accordingly. Turning the adjust-
ment screw clockwise raises the control setpoint, increasing main
valve outlet pressure. Turning the adjustment screw counterclock-
wise lowers the control setpoint, decreasing Main Valve outlet
pressure.
The Model LFCP-15 is equipped with one
3/8
" NPT inlet and two
outlet ports for ease of installation. The unused outlet port may be
plugged or used as a pressure gauge connection.
