Pneumatic Motorized Valves

Pneumatic motorized valves comprise a very wide range of devices. The most common valves are ball valves and butterfly valves with pneumatic actuators. Both types of valves work easily and economically with the pneumatic actuator. These motorized valves have remote function capabilities, cutting off conduits and fluid tanks with pneumatic control. The most common feature of these valves involve severing pipes, food machinery, bypass, distribution, venting, venting installations, mixing and fluid distribution. It is important to note that pneumatic motorized valves function with only open or closed positions and can instantly change between these two states. If you are looking for a control function, it is necessary to select a control valve specifically made for this purpose.

Application

Pneumatic motorized valves are used in all industrial sectors that have a compressed air system (water treatment, process networks, steam system, compressed air, coolant networks, hot water, cold water, water-glycol (heating, cooling, heat exchanger), fire systems, gas systems, fuel systems. They are found in energy sectors, mines, chemical industries, petrochemical plants, water treatment systems, stationery, laundry machines, agriculture, cosmetics, pharmaceuticals etc.

Operation

Dual control: a pneumatic actuator of the rack-and-pinion piston type works the valve shaft, which makes a ¼ turn. A distributor alternately sends a pneumatic signal to one of the two chambers of the cylinder to open and close the valve. Single control: in this case, the cylinder is equipped with piston compression springs. The pneumatic signal executes only two movements: open and close. The second movement occurs from the pressure of the springs. This type of operation provides a fail-safe mechanism by restricting flow.
