Pressure Relief, Sustaining or Backpressure Pilot - SSPV20C

Pressure Relief, Sustaining or Backpressure Pilot - SSPV20C

SSPV20C Series is a remote sensed direct acting, diaphragm actuated Pilot that is used on various configurations of Automatic Control Valves. It is normally held closed by the force of the adjustable spring setting above the diaphragm. It modulates toward an open position when control pressure, exerting force below the diaphragm, exceeds the spring setpoint, and modulates toward a closed position when the control pressure falls below the spring setpoint. The SSPV20C senses control pressure through a tapped port below the diaphragm. The large diaphragm-to-seat ratio allows it to open and close within close pressure tolerances, accurately positioning the Main Valve. Turning the adjustment screw clockwise raises the control setpoint. Turning the adjustment screw counterclockwise lowers the control setpoint. The SSPV20C is equipped with one 1/2" NPT inlet and outlet port and a 1/4 in NPT side sensing port located on the power chamber. The 1/4 in side sensing port is used to monitor upstream or downstream pressure as required by specific valve function.
