    Diaphragm: Nylon Reinforcement With EPDM Rubber: EPDM

     

     

     

    Nylon Reinforcement Diaphragm EPOXY Coated Stainless Steel 304 Pilot Operated Water Pressure Sustaining Relief Valve​

     

     

     

    Description:

     

    A500 is a hydraulically operated, diaphragm actuated control valve that can fulfill either of two separate functions. When installed in-line, it sustains minimum pre-set, upstream (back) pressure regardless of fluctuating flow or varying downstream pressure. When installed as a circulation valve, it relieves excessive line pressure when above maximum pre-set.

     

    Features:

     

    Line pressure driven, Independent operation by water itselfe

       In-line serviceable and Easy maintenance

       Diaphragm with Nylon Reinforcement provide better performance
