CP15SS

Series CP15SS is a direct acting, diaphragm actuated Pilot that automatically reduces a higher upstream (inlet) pressure to a constant downstream (outlet) pressure. It is normally held open by the force of the adjustable spring setting above the diaphragm. The Pilot modulates towards a closed position when outlet pressure exceeds the spring setpoint, lowering the delivery pressure. It modulates towards an open position when the outlet pressure falls below the spring setpoint, increasing the delivery pressure. When a Series CP15SS is installed in the piping circuit of an Automatic Control Valve its throttling action causes the Main Valve to throttle open or closed accordingly. Turning the adjustment screw clockwise raises the control setpoint, increasing Main Valve outlet pressure. Turning the adjustment screw counterclockwise lowers the control setpoint, decreasing Main Valve outlet pressure. The Series CP15SS is equipped with one 3/8 in NPT inlet and three outlet ports for ease of installation. The unused outlet ports may be plugged or used as a pressure gauge connections.
