Specificatie

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 a 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 blue epoxy coating internally and externally for corrosion protection as well as isolation valves and pressure gauges for quick and easy maintenance or repair.
