In ball valves the locking device is a perforated ball. Horizontal rotation of the ball opens and closes the pipe.
AWP ball valves are shut-off valves which are designed for installation in the refrigerant cycles of industrial refrigeration systems. The locking device is a perforated ball that opens and closes the pipe by horizontal rotation that is exerted via the shaft. The 90°-rotation is eiter done by a hand-operated lever or by electric or pneumatic actuators. By default the clearance of the perforation in the ball is reduced compared to the diameter of the pipe. Versions with full clearance are available upon request.
