Typical Installation:

The Zurn 2-ZW209BP is commonly used in buildings where 1-15 GPM low flows are common during off-peak usage. Applications include commercial buildings, residential high-rise systems, and any installation requiring reduction of high inlet pressures to safe and stable outlet pressure with low-flow bypass capability.

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 requiring main valve operation, extending valve life.
• Complete Control System: Includes wye strainer, isolation valves, inlet/outlet pressure gauges, and pilot assembly for simplified installation and maintenance.
• Durable Construction: Blue epoxy-coated ductile iron body with stainless steel trim provides corrosion protection and long service life.
• Adjustable Pressure Control: Pilot adjustable range of 15-120 psi allows precise downstream pressure regulation for various applications.

FAQ

Q: What is the minimum inlet pressure required for the Wilkins 2-ZW209BP?

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

Q: Does the Zurn 2-ZW209BP eliminate the need for additional low-flow bypass valves?

A: Not in all cases. While the integrated bypass handles 1-10 GPM, an additional bypass valve may be needed to bridge the gap between the bypass maximum flow and the main valve minimum continuous flow (15 GPM for 2 inch size).

Q: What is the recommended installation orientation for this valve?

A: The recommended installation orientation is horizontal with the valve cover up for proper operation and maintenance access.
