Orders that ship directly from a manufacturer normally have a firm shipping estimate but those dates are subject to change due to manufacturer production, inventory or shipping. We do our best to estimate ship dates but orders shipping directly from the manufacturer can have unexpected delays. We will confirm tracking information when orders ship directly from a manufacturer but may not have updates or estimates beyond the original estimate. Once your order is placed with the manufacturer, it may not be able to be cancelled even if it hasn't shipped yet.
Please contact support@bottlefillingstations.com to confirm delivery time for a specific product or quantity. Or to inquire about an existing order.
Special Case Shipping Rates
Please note that shipping rates are subject to change at any time. We reserve the right to charge an additional fee in addition to the regularly advertised shipping fee for shipping to remote areas not easily accessible by typical freight carrier means (i.e. islands only accessible by ferry). If your order falls into this category, you will be notified upon receipt of your order, and have the option to complete the purchase with additional fee or to cancel the order. Please note, these instances are very rare, as most locations are reachable by regular freight. If you have any questions, please contact us!

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.
NOTICE: Do not use with water that is unsafe or of unknown quality without adequate disinfection either before or after the system.
