Description
Butterfly valves are designed for use as shut-off or regulating valves for flow control in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
DNOVA-DA pneumatic rotary actuators are designed for automation of industrial shut-off valves control process - gates, ball valves. DNOVA pneumatic actuators are designed for operation both indoors and outdoors. All internal and external parts are anticorrosive coated.
Pneumatic valves 4M310-08 24 V are used for control in pneumatic systems having NAMUR docking surface for installation of valves through through holes in the housing.
APL-410N EX limit switch unit is designed for visual and electrical signaling of end positions of the valve shut-off body. It is mounted from above on the surface of the pneumatic actuator and connected to the actuator shaft - DIN standard. The sealed box usually contains two sensors which monitor the position of the actuator shaft and signalize the end positions. Visual indication of the position can be observed on the body of the unit there is a 3D visual indicator RED-CLOSED and YELLOW-OPEN.
