Automatic Ball Valve

Ball valves with pneumatic drive are used in the building materials industry for the dosage of water and liquid additives. They are much more durable than other valves, performing well after many operation cycles or even after long periods of disuse. Ball valves are typically fast-acting and only used for on/off process, eliminating dosage errors. These qualities make them an excellent choice for shutoff and control applications in the ready-mix industry. They are available in stainless steel as well as plastic, threaded or flanged, suitable for water, air, chemicals, oil, acid, etc.

Accessories for pneumatic actuators

  • Our pneumatic actuators are usually provided with a 5/2 way single solenoid valve having G¼ air inlet/outlet. The air pressure for normal industrial applications should be between 6-8 bar. The coil voltage can be AC or DC with a various voltage from 12 to 220 V which should be specified when ordering.

sfairokrounoi 5a

  • To mark the position of the ball valve (open-closed) an optional limit switch box is available to be mounted on the top of the pneumatic actuator by a stainless steel bracket.
