Description
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.
Pneumatic valves are used for control in pneumatic systems with NAMUR docking surface, to install the valves through holes in the housing.
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.
AFC2000 DNOVA air treatment units are designed to clean compressed air from moisture droplets and solid particles, remove condensate, automatically maintain the pressure at the set level, supply lubricant from the tank in the compressed air flow to the elements of the pneumatic system with a large capacity range from 500 liters/minute to 10 000 liters/minute. The lubricator adds oil with a viscosity of 32 mm²/s (=cSt) at 40°C to the pneumatic system for further lubrication of control components such as pneumatic cylinders and pneumatic valves.
