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. The 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.
Limit switch unit is designed for visual and electrical signaling of the end positions of the shut-off valve, valve or disc gate. It is mounted on top of the pneumatic actuator surface and connected to the actuator shaft in DIN standard. The sealed box usually contains two sensors that monitor the position of the actuator shaft and signalize in extreme positions. OMRON microswitches, inductive sensors or reed switches are used as sensors. Visual indication of the position can be observed on the housing of the unit there is a 3D visual indicator RED-CLOSED and GREEN-OPEN.
