Lug Style Butterfly Valves (Series BV-H)

Lug Style Butterfly Valves with Gear Operator (Series BV-H) are manufactured for high-capacity flow and low operating torque, with effective sealing up to 200 psi. Epoxy coated cast iron body and nickel plated ductile iron disc are standard, but additional options are available upon request.

FEATURES

  • Operator flange conforms designed to work with manual, pneumatic or electric actuators.
  • The rubber seat is non-collapsible, stretch resistant, and blowout proof.
  • The precision machined disc ensures low operating torque and effective sealing up to 200 psi. The hydrodynamically designed disc allows for high capacity flow.
  • One piece shaft design ensures dependability and positive disc positioning.
  • Valves are epoxy coated and incorporate “zerk” style grease fittings for easy lubrication on neck & gearbox (if applicable).
