263RS Watts

Pressure Reducing Pilot

Series 263RS 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 setpoint. The Series 263RS is equipped with 1/2 in NPT inlet and outlet ports and a 1/4" NPT side sensing port. The 1/4 in NPT side sensing port is used to monitor upstream or downstream pressure as required by specific valve function.
