Wilkins ZW205FP Fire Pump Relief Valve

The Zurn Wilkins Model ZW205FP Fire Relief Valve is designed for Fire Suppression Systems to relieve high systempressures. The pilot assembly reacts quickly to increase of upstream pressure to prevent damage to system piping, valves, and sprinklers while maintaining positive pressure on fire pumps. As the water demand increases in the Fire Suppression System the Relief Valve will start to close, directing more water to suppress fires. The Relief Valve will maintain the upstream pressure at the set pressure as long as maximum flow rates of the valve are not exceeded. The Zurn Wilkins Model ZW205FP is designed to open quickly and close slowly to prevent upstream pressure surges.

Specifikim

The Fire Pump Relief Valve shall be a single seated, line pressure operated, diaphragm actuated, pilot controlled globe or angle valve. The valve shall seal by means of a corrosion-resistant seat and resilient, rectangular seat disc. These and other parts shall be replaceable in the field; all such service and adjustments to be possible without removing the valve from the line. The stem of the basic valve shall be guided top and bottom by integral bushings. The basic valve and its pilot control system shall contain no packing glands or stuffing boxes. The diaphragm shall not be used as a seating surface nor shall pistons be used as an operating medium. All internal and external ferrous surfaces shall be coated with a high quality, fusion epoxy coating. The pilot control system shall include a direct-acting, normally closed, spring-loaded, diaphragm actuated pilot valve with the stem guided between the diaphragm assembly and seat disc. To ensure precise pressure relief, the appropriately rated pilot valve shall be field adjustable within the pressure control range of the spring. The Fire Pump Relief Valve shall be a ZURN WILKINS Model ZW205FP.
