Model LFCP14-1

Rate-of-Flow Pilot

Size: 

3/8

" NPT

The Model LFCP14-1 is a direct acting, diaphragm actuated Pilot 

that senses and responds to changes in a differential pressure 

signal. The differential pressure signal is usually created by an 

orifice plate located inline either upstream or downstream of the 

Main Valve. The Pilot has two sensing chambers, one above and 

one below the diaphragm. The "low" pressure signal is sensed 

above the diaphragm, and the "high" pressure signal is sensed 

below the diaphragm.
An increase in flow rate causes the differential pressure across 

the orifice plate to increase. The Pilot modulates toward a closed 

position when the differential pressure signal increases above the 

control setpoint, causing the Main Valve to modulate toward a 

closed position, decreasing flow rate.
A decrease in flow rate causes the differential pressure across 

the orifice plate to decrease. The Pilot modulates toward an open 

position when the differential pressure signal decreases below the 

control setpoint, causing the Main Valve to modulate toward an 

open position, increasing flow rate. Turning the adjustment screw 

clockwise raises the control setpoint, increasing flow rate. Turning 

the adjustment screw counterclockwise lowers the control set-

point, decreasing flow rate.
The LFCP14-1 is equipped with one 

3/8

" NPT inlet and two outlet 

ports for ease of installation, and two 

1/8

" NPT sensing ports. The 

1/8

" sensing port above the diaphragm is used to monitor the "low 

pressure" differential signal, and the sensing port below the dia-

phragm is used to monitor the "high pressure" differential signal.
