Description

The Zurn Wilkins Model ZW209 is a 6-inch pilot-operated pressure reducing valve designed for fire protection and industrial applications. It reduces high inlet pressures to safe, stable outlet pressures, with pressure regulation independent of flow rate. Constructed with a durable ductile iron body, stainless steel seat, and Buna-N disc, it is internally and externally epoxy coated for corrosion resistance. Standard features include isolation valves, pressure gauges, and a wye-type strainer for easy maintenance. This model utilizes an IPS grooved connection for installation flexibility and is NSF/ANSI/CAN 61 certified. It includes a reverse side pilot and handles water temperatures from 33°F to 140°F, with a pilot spring range of 50-165 PSI.

Additional Details

The Zurn Wilkins Model ZW209 Pilot Operated Pressure Reducing Valve is designed to reduce high inlet pressures to safe and stable outlet pressure across a wide range of applications, including fire systems. This 6-inch valve features an IPS grooved connection and is configured with a reverse pilot, ensuring constant downstream set pressure regardless of flow rate.

Features

  • Main valve body and bonnet are epoxy coated internally and externally for enhanced corrosion protection.
  • The pilot assembly reacts to changes in downstream pressure, allowing the main valve to modulate between closed and open positions for consistent outlet pressure.
  • Pressure regulation is not dependent upon flow rate, ensuring minimal pressure loss through the valve.
  • Includes standard isolation valves and pressure gauges for quick and easy maintenance or repair.
  • Equipped with a "Wye" type strainer.

FAQs

What is the primary function of the Zurn Wilkins Model ZW209 valve?

It is a pilot-operated pressure reducing valve designed to lower high inlet pressures to a consistent, safe, and stable outlet pressure, independent of the flow rate. It prevents downstream damage by sealing shut once the pilot setting is reached.

What materials are used for the main valve body and internal components?

The main valve body and bonnet are made from Ductile Iron ASTM A536. Key internal components include a Stainless Steel disc guide, seat, and stem, with a Buna-N rubber disc and Nylon Reinforced Buna-N diaphragm.

What type of connections does this 6-inch ZW209 valve use?

This specific 6-inch ZW209 model features IPS Grooved end connections. These connections are ideal for joining pipes, fittings, and other components in a grooved piping system.

Is the ZW209 valve approved for potable water applications?

Yes, the valve meets the requirements of NSF/ANSI/CAN 61, indicating it is certified for applications involving potable water with a maximum weighted average lead content of 0.25%.

What is the maximum pressure rating for this grooved connection valve?

For grooved connections, the Zurn Wilkins ZW209 valve has a maximum pressure rating of 300 psi. It also has a minimum inlet pressure requirement of 10 psi.
