Description

The Zurn Wilkins Model ZW215FP is a 10-inch fire pump suction control valve with ANSI Class 300 flanged connections, crucial for fire suppression systems. It prevents fire pumps from over-drawing water, which protects the pump and supply network from damage due to low suction pressures. This valve automatically closes if suction pressure drops below a set point and modulates to maintain optimal pressure as needed. Constructed with a ductile iron body, stainless steel components, and red epoxy coating for corrosion resistance, it is FM Approved and designed for durability. It operates within a water temperature range of 33°F to 140°F with a pilot spring range of 10-30 psi. Item number 10-ZW215FPY.

Additional Details

The Zurn Wilkins Model ZW215FP Fire Pump Suction Control Valve is a 10 inch, Class 300 flanged valve designed for fire suppression systems. It prevents fire pumps from over-drawing the water supply, protecting both the pump and the supply network from damage due to very low or negative suction pressures.

The valve modulates to maintain suction pressure at a set point, closing if pressure drops below the set point and reopening as pressure rises.

Operation and Control

  • Reacts quickly to changes in suction pressure to modulate flow
  • Automatically closes if suction pressure drops below set point
  • Automatically opens and modulates as suction pressure rises to the set point

Construction & Features

  • Ductile Iron body and bonnet, Stainless Steel disc guide, seat, stem, and spring
  • Buna-N Rubber disc and Nylon Reinforced Buna-N diaphragm for reliable sealing
  • All internal and external ferrous surfaces are coated with a red epoxy coating for corrosion protection
  • Includes a pilot assembly with a "Wye" Type Strainer, Sensing Line Test Cock, Visual Position Indicator, and 3/8" Flare Sensing Line Connection
  • Equipped with ANSI Class 300 Flanges for robust connections

Installation Note: For 6 inch and larger valves, the recommended installation orientation is horizontal with the valve cover up to ensure proper air bleeding and ease of maintenance.
