Automatic Control Valves



Pressure Reducing Pilot

Lead Free* Models Available


3/8 in


The Model CP15-1SS is a remote sensed, direct acting, diaphragm
actuated Pilot that is used on various configurations of Automatic
Control Valves.

It is normally held open by the force of the adjustable spring setting
above the diaphragm. The Pilot modulates towards a closed position when remotely sensed pressure exceeds the spring setpoint, and modulates towards an open position when the remotely sensed pressure falls below the spring setpoint.

Turning the adjustment screw clockwise raises the control setpoint.
Turning the adjustment screw counterclockwise lowers the control

The Model CP15-1SS is equipped with one 3/8 in NPT inlet and three
outlet ports for ease of installation, and a 1/8 in NPT side sensing port. The 1/8 in side sensing port is used to monitor upstream or downstream pressure as required by specific valve function.
