High Performance Butterfly Control Valves - DISKFLO

The DISKFLO is available in either (1) double offset or (2) triple offset designs. DISKFLO control valves 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 utilising the pressure drop across the valve to aid the seating process. Since much of the seating force is supplied by the pressure drop, the need for strong actuator seating force – and therefore breakout torque – is reduced. Combined with DISKFLO's high-thrust cylinder actuator and eccentric-cammed disc, it is possible to achieve high-performance throttling – even in large pressure drops close to the seat.
