    Product Features

  • 100% Bidirectional factory tested valve product
  • Extended neck design for applications that require insulation
  • One piece uni-body construction of cast iron designed to accommodate both ANSI and DINF flanges
  • Integral mounting flange will accept all styles of hand levers, manual gear operators
    and pneumatic or electric actuators
  • 2 piece stainless steel plate functions not only as a bushing but as a retention plate for
    possible blow-out
  • The liner is constructed by bonding an elastomer seal to a split, rigid phenolic backup

    ring which forms the outside periphery of the seat

  • This cartridge design helps prevent the possibility of blowouts and provides for easy

    replacement. The ribs on the outside elastomer provide an interface seal with flanges
    for no-gasket installation

  • Two piece shaft design eliminates the need for bolts or pins to attach shaft to disc,

    thereby removing potential leak path of media. Two piece shaft design allows for a
    reduction in disc thickness, creating less obstruction in waterway which results in
    larger Cv values

  • Field replaceable seats are a standard design feature
