Pneumatic ball valves
FUNCTION: It is used as a shut-off part in plants with remote control. Valve motion is done via pneumatic drive with exiting spindle rotation from 0 - 90°. Instructions are done by electric impulse, via electromagnetic valves or slide valve. There is a signal device which provides confirmation about command that was carried out. Signaling device can be used for visual control with electronic or pneumatic signal. Air pressure for engine power: Pn= 6-8 bar.
