Description

The ZURN 6 inch ZW215FP Fire Pump Suction Control Valve is a globe-style control valve specifically designed for fire suppression systems. It utilizes 6 inch IPS grooved connections and ductile iron construction with a stainless steel seat. This FM® Approved valve prevents fire pumps from over-drawing water, maintaining a minimum inlet pressure to avoid cavitation and potential backflow conditions. Its red epoxy coating provides internal and external corrosion resistance, ensuring long-term reliability. The valve operates within a water temperature range of 33°F to 140°F, providing critical suction pressure regulation for fire protection pumps. Item number 6-ZW215FPG.

Connections

  • The 6 inch IPS Grooved connections are designed to integrate directly into existing IPS grooved piping within fire suppression systems.
  • The valve connects to the suction side of a fire pump to regulate incoming water pressure.
  • A 3/8 inch flare sensing line connects externally from the pump's suction side to the pilot control chamber to monitor and control pressure accurately.

Additional Details

The 6 inch ZURN Model ZW215FP Fire Pump Suction Control Valve is designed to regulate suction pressure in fire suppression systems.

It prevents fire pumps from over-drawing water, which can lead to damage from low or negative pressures, and maintains a minimum inlet pressure to prevent cavitation and backflow.

Key Features

  • Corrosion Resistance: Internal and external surfaces are coated with a high-quality red epoxy, FDA approved.
  • Precise Control: Modulates to keep suction pressure at a set point, reacting quickly to pressure changes.
  • Easy Maintenance: Includes a test cock on the sensing port for quick bleeding of the sensing line.
  • Reliable Operation: Single seated, line pressure operated, diaphragm actuated, pilot controlled globe valve.

Construction Details

  • Main Valve Body: Made from Ductile Iron ASTM A536 for durability.
  • Seat: Stainless Steel ensures long-term performance.
  • Disc: Features a Buna-N Rubber disc for effective sealing.
  • Diaphragm: Constructed from Nylon Reinforced Buna-N for resilience.
  • Pilot Assembly: Includes a "Wye" Type Strainer, Visual Position Indicator, and Copper Tubing and Brass Fittings.

Caution: For 6 inch and larger valves, horizontal installation with the valve cover up is required to ensure proper air bleeding and maintenance.

FAQs

What is the primary function of the ZURN ZW215FP Fire Pump Suction Control Valve?

The primary function is to prevent fire pumps from over-drawing water from the supply, which can cause damage to the pump and the supply network due to low or negative suction pressures. It maintains a minimum inlet pressure to prevent cavitation and backflow.

What type of connections does this 6 inch ZW215FP valve use?

This ZW215FP valve features 6 inch IPS Grooved connections, designed for direct integration into compatible grooved piping systems.

What materials are used in the construction of the ZW215FP valve?

The main valve body and bonnet are made of Ductile Iron ASTM A536. It features a Stainless Steel seat and disc guide, with a Buna-N Rubber disc and Nylon Reinforced Buna-N diaphragm. The valve is internally and externally red epoxy coated.

What is the recommended installation orientation for the 6 inch ZW215FP valve?

For 6 inch and larger valves, horizontal installation with the valve cover facing upwards is required. This ensures proper air bleeding from the cover and facilitates maintenance.

What is the maximum operating temperature for this valve?

The ZURN ZW215FP valve is designed to operate with water temperatures ranging from 33°F to 140°F.
