Additional Details

The 8 inch Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is designed for many applications requiring the reduction of high inlet pressures to a safe and stable outlet pressure, particularly in Fire Suppression Systems where steady downstream pressure and high flow rates are essential.

The pilot assembly reacts to changes in downstream pressure, allowing the main valve to modulate between closed and open positions to ensure a constant downstream set pressure. Once the downstream pressure reaches the pilot setting, the main valve will seal shut, preventing potential downstream damage. The valve features internal and external epoxy coating for corrosion protection, and includes isolation valves and pressure gauges for simplified maintenance and repair.
