When a check valve is oversized for the expected flow, it creates low flow (low velocity) conditions. In no event will we be liable for any loss or damage including without limitation, indirect or consequential loss Field Adjustable and/or Supplied Factory Preset.
Changing the spring to a lower cracking pressure can be one way to reduce chattering while improving the stability of the valve. Cracking pressure can have a significant impact on the compatibility of a check valve with its intended application. Youll need to select the most appropriate valve with the right internal component design to achieve the required cracking pressure and overall pressure differential.
