Application
The Zurn Wilkins Model ZW209 Pilot Operated Pressure
Reducing Valve 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 closed and open position ensuring a constant
downstream set pressure. Once the downstream pres-
sure reaches the pilot setting, the main valve will seal shut
preventing damage downstream. Pressure regulation is not
dependent upon flow rate, resulting in minimal pressure loss
through the valve. In addition the Model ZW209 comes stan-
dard with epoxy coating internally and externally for corrosion
protection, as well as isolation valves and pressures gauges
for quick and easy maintenance or repair.
Standards Compliance:
• ANSI/AWWA C530
• Meets the requirements of NSF/ANSI 61*
