Betterfly Valve

Manual Air Actuated Betterfly Valve Microswitch Unit Multiposition Handle

CAD Drawings



  • SANITARY: The BETTERFLY valve is entirely stainless steel (order type 304 or 316)
  • COMPACT: Designed to fit where space is short, it is available with clamp, weld-on or bevel-seat ends. The BETTERFLY is a complete valve unit - ready to install in your pipeline.
  • LEAK-FREE PERFORMANCE: A heavy-duty, highly elastic seat is held firmly and compressed by the two halves of the valve body. It forms a tight seal around the shaft, preventing leakage along the stem.
  • RELIABLE ACTION: The disc rotates 90°. Open, it is parallel to the product flow. For positive shutoff, it seats into the heavy-duty gasket; the handle with spring-loaded button locks the valve open or closed.
  • INGENIOUS AND ADAPTABLE: The valve dismantles quickly into two symmetrical parts: you can reassemble a complete BETTERFLY, with matching or mixed ends, from any two halves.
Maximum In Line Flow Pressure
Valve Size 1" to 2" 150psi
Valve Size 2 1/2" & 3" 120psi
Valve Size 4" & 6" 100psi


  • AVOID CORROSION: The actuator body and adaptor are made entirely of stainless steel.
  • SMOOTH OPERATION: The brass double-acting rack and pinion gear insures trouble free performance. Choose from Air to open - Air to close, or Air to open - Spring return (fail-safe). If you need the spring to open the valve, the action is easily reversed.
  • VERSATILE DESIGN: The manual handle assembly and the air-actuator, mount on the identical valve body: conversion can be accomplished in the field in seconds.
  • EXTRA INSURANCE: The square-ended shaft of the pinion gear remains exposed. Should the air fail, one quarter turn of the shaft operates the valve manually.
  • SEAT MATERIAL: To be compatible with a wide variety of products, the valve is available with choice seats: Silicone (standard), EPDM (request), viton®(request, surcharge), and Teflon Coated viton® (request, surcharge).
  • Aluminum Actuator For 6" Valve: A rack and pinion heavy duty actuator housed in an aluminum body.
Viton® is a registered trademark of DuPont Dow Elastomers.


The unit can be installed on either actuator: Air-to-air or Air-to-spring. The cam is bolted into the gear shaft and rotates with the disc, triggering one switch when the valve is fully open, the other when fully closed. ALSO AVAILABLE WITH SOLENOID VALVE.



THE ACTION: Pull the spring-loaded handle away from the sleeve - the pin disengages.
Rotate the disc to desired position: Open - Intermediate positions 1, 2, 3, or Closed.
Release the handle -- the pin seats and the angle of the disc is locked in.
Note: the disc and the stem of the Multiposition BETTERFLY is not interchangeable with either manual or air actuated model.
