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.

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:

Local codes shall govern installation requirements. Unless otherwise specified, the assembly shall be mounted in accordance with the manufacturer's instructions and the latest edition of the Uniform Plumbing Code. The assembly shall be installed with sufficient side clearance for testing and maintenance. The Model 70XL may be installed in any position. If installed in a pit, vault or indoors, specify the "SC" sealed cage option. Multiple installations are recommended for wide demand variations or where the desired pressure reduction is more than 4 to 1 (i.e.: 200 psi inlet reduced to 50 psi outlet). CAUTION: Anytime a reducing valve is adjusted, a pressure gauge must be used downstream to verify correct pressure setting. Do not bottom adjustment bolt on bell housing.

 

Standards Compliance:

ASSE 1003 Listed; IAPMO Listed; CSA Certified; City of Los Angeles Approved; NSF/ANSI/CAN 61 & 372

 

Features & Benefits:

  • Balanced Piston Design: Enables smooth and responsive reaction to changes in system flow demand while providing protection from inlet pressure variations.
  • Unitized Replaceable Cartridge: Reduces time involved with cleaning and maintenance, all internal corrosion-resistant parts included in a single replaceable cartridge.
  • Integral Bypass Design: Direct acting integral bypass prevents buildup of excessive system pressure caused by thermal expansion in both flow and no-flow conditions.
  • Lead-Free Compliance: Meets NSF/ANSI/CAN 61 & 372 requirements with less than 0.25% weighted average lead content, ideal for potable water applications.
