وصف
Butterfly valves DNOVA al-316l-epdm are designed for use as shut-off or regulating valves for flow control in heat and water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries. Butterfly valves should be installed only between collar flanges.
Pneumatic double-acting 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. Visual indication of the position can be observed on the body of the unit there is a 3D visual indicator RED-CLOSED and GREEN-OPEN.
Manual doubler with disengaging clutch DNOVA APL-210N MON allows to manually set the required positioning of valves, dampers and other quarter-turn devices when replacing pneumatic, electric or hydraulic quarter-turn actuators. Suitable for both indoor and outdoor installation. The modular design of the manual doubler is designed to provide the most efficient and effective solution to the full range of manual override applications.
