Description

The Zurn Wilkins Model ZW209 is a 6-inch pilot-operated pressure reducing valve with ANSI Class 300 flanged connections, primarily used in fire suppression systems to maintain safe and stable downstream pressure from high inlet pressures. Its pilot assembly precisely modulates flow, while an automatic shut-off prevents downstream damage once the set pressure is reached. The valve features a durable ductile iron body with internal and external epoxy coating for superior corrosion resistance. Standard isolation valves and pressure gauges simplify maintenance. Certified to NSF/ANSI/CAN 61 and ANSI/AWWA C530, it ensures reliable, lead-free operation for critical applications. Item number 6-ZW209FPY.

Additional Details

The Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is engineered to reduce high inlet pressures to a safe and stable outlet pressure, making it ideal for fire suppression systems and other demanding applications. This specific 6 inch ZW209FPY model features ANSI Class 300 flanged connections for robust and secure installation.

Operation & Performance

  • Utilizes a pilot assembly that reacts to changes in downstream pressure, allowing the main valve to modulate between closed and open positions to ensure a constant downstream set pressure.
  • The valve automatically seals shut once the pilot setting is reached, preventing downstream damage.
  • Pressure regulation is independent of flow rate, resulting in minimal pressure loss.
  • Pilot control is field adjustable from 15 psi to 120 psi.

Construction & Durability

  • Main valve body is constructed from Ductile Iron ASTM A536 for strength and longevity.
  • All internal and external ferrous surfaces are coated with a high quality, fusion epoxy coating for superior corrosion protection.
  • The stem of the basic valve is guided top and bottom; the diaphragm is not used as a seating surface.

Maintenance & Repair

  • Comes standard with isolation valves and pressure gauges, simplifying quick and easy maintenance and repair procedures.
  • Includes a "Wye" Type Strainer as part of the pilot assembly.

Caution: The closing speed control (optional) on this valve should always be open at least three (3) turns off its seat.
