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.
Double-acting pneumatic rotary actuators and pneumatic rotary actuators with return springs are designed for automation of control process of industrial shut-off valves - gates, ball valves. DNOVA pneumatic actuators are designed for operation both indoors and outdoors. All internal and external parts are anticorrosive coated.
Limit switch unit is designed for visual and electrical signaling of valve end positions. It is mounted on top of the pneumatic actuator surface 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. The 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.
The HDM worm gear manual doubleturn actuator with reduction gearbox allows the manual setting of the required positioning of the shut-off valve by a quarter turn, acting as an alternative to pneumatic, electric or hydraulic quarter-turn actuators. Suitable for both indoor and outdoor installation. The modular design of the manual override is intended to provide the most efficient and effective solution to the full range of manual override applications.
