The DISKFLO Eccentric / Triple disc rotary control valve achieves bi-directional bubble-tight shutoff while maintaining low breakout torque at both high & low pressure drops. It is available in ANSI Classes 150 thru 1500 and in sizes 2 through 72-inch. This MASCOT rotary valve is available in carbon steel, 316 stainless steel and other alloys.
Eccentric Disc seating assures low breakout torque by utilizing 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 especially high-performance throttling – even in large pressure drops close to the seat.
Eccentric / Triple Cammed Disc
A double offset and triple offset have been designed into the disc to lift it out of the seat immediately upon actuation. This avoids wear on the seat and disc, reducing leakage and parts replacement. It also improves throttling by eliminating friction.
Capacity greater than globe, plug and cammed control valves
Increased flow capacity
Purged bonnet and lubricator options
Carbon steel, 316 stainless steel and other alloys.
Metal or Teflon® seats easily installed
