DISKFLO High Performance Butterfly Valve

DISKFLO High Performance Butterfly Valve

The DISKFLO is available in either (1) double offset or (2) triple offset designs. DISKFLO controlvalves achieve bi-directional bubble-tight shutoff while maintaining low breakout torque at both high& low pressure drops. It is available in ANSI Classes 150 thru 4500 and in sizes 2 through 72-inch.Available is standard materials such as carbon steel, 316 stainless steel and other castable alloys.

Eccentric Disc seating assures low breakout torque by utilizing the pressure drop across the valveto aid the seating process. Since much of the seating force is supplied by the pressure drop, theneed for strong actuator seating force – and therefore breakout torque – is reduced. Combinedwith DISKFLO's high-thrust cylinder actuator and eccentric-cammed disc, it is possible to achievehigh-performance throttling – even in large pressure drops close to the seat.
