5000 Series Butterfly Valves

Our 5000 series Butterfly valves are manufactured in accordance with the specifications from MSS SP 67, Manufacturers Standardization Society and API-609, American Petroleum Institute, latest revisions.

Both Lug and Wafer style valves are designed for ANSI 125/ 150 lb. class flanges and are rated at 200 PSI WOG service. Omni Seal Butterfly Valves make an excellent choice by combining the balance of an economical valve with the performance you expect in a commercial, HVAC and an industrial butterfly valve.

  • 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
