The ball valve is used as a shut-off valve in heat supply systems, water supply systems, in steam, fuel and pneumatic systems with compressed air and neutral gases. Installation of valves of this series is possible in systems transporting liquid and gaseous media (water, oil, oils, steam, air, alcohols, glycol, etc.), non-aggressive to the valve materials. The use of ball valves as control valves is not allowed.
Double-acting pneumatic actuators PA-DA-x use two ports to supply the control medium and create movement in both directions, both for opening and closing the valve. One port is used to move the piston in one direction, and the other - to move in the opposite direction.
Electromagnetic control is carried out using voltage coils 12-AC, 12-DC, 24-AC, 24-DC, 110-AC, 220-AC. Depending on the model, the distributors have one-way or two-way control.
Magnetic switch Elephant ALS200D is designed to convert the final values of the shaft position of pneumatic drives or shut-off valves into electrical signals. The operation of the magnetic switch is based on the operation of two independent, completely sealed, magnetic sensors located inside the U-shaped housing.
