Wilkins ZW207 Excess Pressure Shutdown Valve, Lead-Free*

The Zurn Wilkins Model ZW207 Excess Pressure Shutdown Valve is designed for many applications where protection of downstream components from high pressure is required. The ZW207 will quickly close to protect downstream components from high pressure when upstream pressure rises above the set pressure of the pilot valve. The Excess Pressure Shutdown Valve will close when inlet pressure rises because of damage, failure, or fouling to an upstream pressure reducing valve, a quick closing valve downstream, or a sudden upstream pressure surge. When the upstream pressure is below the set point of the pilot assembly, the main valve will remain fully open. In addition the Model ZW207 comes standard with epoxy coating internally and externally for corrosion protection, as well as isolation valves and an outlet pressure gauge for quick and easy maintenance or repair. Meets the requirements of NSF/ANSI 61* *Product contains weighted average lead content less than 0.25% for wetted surfaces.
Specification
  • The Excess Pressure Shutdown Valve shall be a diaphragm actuated, pilot controlled valve. The main valve body shall be ductile iron ASTM A 536. The stem of the basic valve shall be guided top and bottom. The diaphragm shall not be used as a seating surface. All internal and external ferrous surfaces shall be coated with a high quality, fusion epoxy coating. The pressure pilot control shall be field adjustable from 50 psi to 200 psi. The valve shall be certified to NSF/ANSI Standard 61. The Excess Pressure Shutdown Valve shall be a ZURN WILKINS Model ZW207.
