Product FAQ

Does Zurn Wilkins manufacture a valve that will shut off the water supply in the event that a Pressure Reducing Valve fails?

  • ​Yes. The Zurn Wilkins ZW207 Excess Pressure Shutdown Valve is an Automatic Control Valve designed to shut off the water in the event of an over-pressure condition.  The valve's shutdown pressure is adjustable by the end user, typically set approximately 10 psi higher than the Pressure Reducing Valve.  In the event that the Pressure Reducing valve fails, The ZW207 will shut off the water supply, thus protecting downstream equipment from damage due to high pressure.  For more information, please visit our web site at http://www.zurn.com/Pages/ProductDetails.aspx?NodeKey=428565

When the ZW207 Excess Pressure Shutdown Valve shuts off the water supply, does the valve have to be reset when the pressure returns to normal?

  • ​The ZW207 Excess Pressure Shutdown Valve does not require any form of resetting.  Upon the pressure dropping down to its normal setting, the ZW207 will reopen and allow flow to occur.  For more product information, please visit our web site athttp://www.zurn.com/Pages/ProductDetails.aspx?NodeKey=428565
