Description
Ball valves are used as shut-off valves in heat and 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 materials of the valve. Use of ball valves as regulating valves is not allowed.
Pneumatic rotary actuator is designed to automate the process of control of industrial valves, as well as to determine the position of the valve shut-off body.
Electropneumatic rotary positioner is used to control pneumatic rotary actuators by means of electric controller or control system with analog DC output signal range from 4 to 20 mA.
