Description
Parker A4WS Adaptomode Weld-End Pressure Regulator with Pilot Electric Shut-Off is a high-performance, pilot-operated valve designed to precisely control inlet pressure in industrial refrigeration systems. Built with a rugged cast steel body that welds directly into the line, the A4WS eliminates the need for flanges and ensures a streamlined fluid flow. Its integrally mounted solenoid must be energized for the valve to function, providing complete shut-off when de-energized ideal for defrost cycles and system safety. The valve features a stainless steel diaphragm, chrome-plated pilot seat, and a characterized modulating plug for accurate pressure regulation.
