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. Installation of valves of this series is possible in systems transporting liquid and gaseous media (water, oil, oils, steam, air, alcohols, glycol, etc.) not aggressive to 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 220V 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 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 housing of the unit there is a 3D visual indicator RED-CLOSED and YELLOW-OPEN.
Air treatment unit AFC2000 is designed to clean compressed air from moisture droplets and solid particles, remove condensate, automatically maintain the pressure at a preset level, supply lubricant from the tank in the compressed air flow to the elements of the pneumatic system with a wide range of throughput 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.
