Butterfly Control Valve
The high-performance DiskFlo Butterfly Valve is used to achieve bi-directional bubble-tight shutoff while maintaining low breakout torque at high and low pressure drops. The high-performance DiskFlo Butterfly Valve uses pressure assisted Jam-lever toggle seating concepts. By utilizing the pressure drop across the valve to aid the seating process, Jam-lever toggle seating assures low breakout torque.
The need for strong actuator seating force is reduced since much of the force is supplied by the fluid pressure. To achieve especially high-performance throttling, even in large pressure drops close to the seat, it is combined with a MASCOT high thrust cylinder actuator and a double eccentric cammed disc.
