Description:

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 pressure
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 adjustment screw
clockwise raises the control setpoint, increasing main valve outlet
pressure. Turning the adjustment screw counterclockwise lowers
the control setpoint, decreasing Main Valve outlet pressure.

The Model LFCP-15 is equipped with one 3/8 in NPT inlet and two
outlet ports for ease of installation. The unused outlet port may be
plugged or used as a pressure gauge connection.
