Pressure Reducing Pilot

Lead Free* Models Available


1/2 in


The Model 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

The Model 263RS is equipped with 1/2" NPT inlet and outlet ports
and a 1/4 in 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.
