Pressure-assisted seating achieves bi-directional shut-off and low breakout torque.
The OpDX™ butterfly control valve is a high performance rotary valve with an eccentric cammed disc that ensures accurate throttling. Its same flangless body (wafer) serves ANSI classes 150, 300, and 600 in 2″, 3″, 4″, 6″ and 8″ sizes. With our piston and cylinder actuator, this butterfly valve has greater flow capacity than any globe, plug, and cammed control valve.
