Typical Installation:

The Zurn 3-ZW209BP is commonly used in commercial buildings where low flows between 1-15 GPM are typical during off-peak usage. Applications include multi-story buildings, institutional facilities, and industrial water distribution systems requiring constant downstream pressure control with integrated low-flow handling capability. Installation includes inlet and outlet shut-off valves, wye strainer upstream, and pressure gauges for monitoring.

Standards Compliance:

ANSI/AWWA C530; NSF/ANSI/CAN 61 (0.25% MAX. WEIGHTED AVERAGE LEAD CONTENT)

Features & Benefits:

• Integrated Low-Flow Bypass: Handles flows up to 10 GPM during off-peak demand without opening main valve, providing seamless pressure control.
• Durable Epoxy Coating: FDA-approved blue epoxy coating on all internal and external surfaces provides superior corrosion protection and extends valve lifespan.
• Complete Installation Package: Includes wye strainer, isolation valves, inlet/outlet pressure gauges, and pilot assembly for simplified installation and maintenance.
• Adjustable Pressure Control: Field-adjustable pilot spring range from 15-120 psi allows precise downstream pressure settings for various applications.

FAQ

Q: What is the minimum inlet pressure required for the Wilkins 3-ZW209BP?

A: The minimum inlet pressure is 10 psi higher than the set point or the additional body friction loss at the intended flow rate, whichever is higher.

Q: Can the Zurn 3-ZW209BP be installed vertically?

A: The recommended installation orientation is horizontal with the valve cover up. Valves 6 inches and larger should only be installed horizontally due to air bleeding and maintenance requirements.

Q: How does the low-flow bypass function on this valve?

A: The integrated PRXL bypass is preset to a slightly higher pressure than the main pilot control. When the main valve closes at set point, the bypass remains open to handle flows up to 10 GPM until downstream pressure reaches the bypass set point.
