ZW209BP Pilot Operated Water Pressure Reducing Valve with Low Flow By-pass, Lead-Free*

The Zurn Wilkins Model ZW209BP Pilot Operated Pressure Reducing Valve with Low Flow By-pass is designed for many applications where the reduction of high inlet pressures to safe and stable outlet pressure is required. The pilot assembly reacts to changes in downstream pressure allowing the main valve to modulate between the open and closed position ensuring a constant downstream set pressure. Once the downstream pressure reaches the pilot setting, the main valve will seal shut. When the main valve closes, the low flow bypass is set to a slightly higher pressure which allows it to handle very low flows up to 10 GPM when there is off peak demand. (An additional bypass may be needed to handle flows between the bypass and main valve minimum flow.) In addition the Model ZW209BP comes standard with epoxy coating internally and externally for corrosion protection as well as isolation valves and pressure gauges 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.

Spécification

The Pressure Reducing 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 pilot control shall be field adjustable from 15 psi to 150 psi. The valve shall be certified to NSF/ANSI Standard 61. The Pressure Reducing Valve with by-pass shall be a ZURN WILKINS Model ZW209BP.
