Actuated Betterfly Valve
valve is entirely stainless steel (order type 304 or 316)
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.
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.
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
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.
In Line Flow Pressure
The actuator body and adaptor are made entirely of stainless steel.
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.
DESIGN: The manual handle assembly and the air-actuator, mount
on the identical valve body: conversion can be accomplished in
the field in seconds.
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®
Actuator For 6" Valve: A rack and pinion heavy duty actuator
housed in an aluminum body.

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.
