Description
Ball valve DNOVA is used as a shut-off valve in heat and water supply systems, in steam, fuel and pneumatic systems with compressed air and neutral gases. The valves of this series can be installed in systems transporting liquid and gaseous media (water, oil, oils, steam, air, alcohols, glycol, etc.) that are not aggressive to the valve materials.
Pneumatic rotary actuators are designed for automation of control process of industrial shut-off valves - gates, ball valves. Pneumatic actuators DNOVA are designed for operation both indoors and outdoors. All internal and external parts are anticorrosive coated.
Pneumatic valves 4M310-08 220 V are used for control in pneumatic systems with NAMUR docking surface, to install the valves through holes in the housing.
Limit switch unit APL-410N EX 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 YELLOW-OPEN.
