Description

The Zurn Wilkins ZW215FP 10 inch Fire Pump Suction Control Valve with IPS grooved connections is designed for fire suppression systems. This globe-style valve prevents fire pumps from over-drawing water, which can cause pump damage and supply network issues from low or negative suction pressures. It maintains a minimum inlet pressure to prevent cavitation and backflow, ensuring system integrity. The valve features durable ductile iron construction with a corrosion-resistant red epoxy coating and a stainless steel seat for longevity. It is FM Approved for reliable performance in critical fire safety applications. Item number 10-ZW215FPG.

Connections

  • This valve features IPS Grooved connections designed for a 10 inch pipe system.
  • The grooved ends are compatible with AWWA C606 standards for a maximum of 300 psi inlet pressure.

Installation

  • For 6 inch and larger valves, including this 10 inch model, the recommended installation orientation is horizontal with the valve cover up.
  • This orientation is crucial for proper bleeding of air from the valve cover and for ease of maintenance.

Additional Details

The 10 inch Zurn Wilkins ZW215FP Fire Pump Suction Control Valve is designed to control suction pressure for Fire Suppression Systems, preventing fire pumps from over-drawing from the water supply and mitigating damage due to low or negative pressures.

This valve maintains a minimum inlet pressure to a Fire Protection Pump, effectively preventing cavitation and potential backflow conditions.

Features

  • Designed for Fire Suppression Systems
  • Prevents cavitation and backflow
  • Modulating action maintains suction pressure within narrow limits
  • Factory set to maintain minimum inlet pressure
  • Quick pilot assembly reaction to pressure changes
  • Internal and external ferrous surfaces are coated with a high-quality flu-eon epoxy coating for corrosion resistance
  • Sensing port includes a test cock for quick bleeding of the sensing line
  • Service and adjustments possible without removing the valve from the line

Construction Materials

  • Main Valve Body: Ductile Iron ASTM A536
  • Main Valve Bonnet: Ductile Iron ASTM A536
  • Disc Guide: Stainless Steel
  • Seat: Stainless Steel
  • Disc: Buna-N Rubber
  • Diaphragm: Nylon Reinforced Buna-N
  • Stem: Stainless Steel
  • Spring: Stainless Steel
  • Pilot System Piping: Copper tubing

Operation

  • Utilizes a pressure relief pilot valve (Model PV-RLF) installed on the discharge side of the control circuitry.
  • The pilot valve is direct acting, normally closed, and spring-loaded with a diaphragm.
  • A sensing line connects the pump's suction side to the pilot control chamber.
  • Suction pressure exceeding the pilot's preset causes the pilot valve to open, and the adjustable spring seeks to keep it closed, resulting in a modulating action to maintain pressure.
