A 2-Way, diaphragm actuated, spring-loaded, pressure sustaining/relief pilot valve, applicable for service on pressure sustaining/relief valve trims. It modulates to maintain a steady, pre-set pressure, upstream of the valve’s location. As upstream pressure rises above the set value, the CXPS opens to allow water flow between its “COM” and “OUT” ports, relieving the water from the valve’s control chamber and causing the valve to open. As upstream pressure falls below the set value, the CXPS throttles, restricting the flow out of the valve’s control chamber, limiting the valve’s opening or causing it to close (if necessary).
