Butterfly valve WBV3232E-2W-Fb-H with pneumatic spring-return actuator

Butterfly valves DNOVA WBV3232E-2W-Fb-H are intended for use as shut-off or control valves for flow control in heat supply systems, water supply, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.

Pneumatic distributor DNOVA 4V320-10 220V is used to change the direction, start, stop the flow of compressed air in the pneumatic system depending on the external control action.

The DNOVA APL-410N EX limit switch unit is an electrical device designed to open and close the working circuit and to visualize the positions of the shut-off element of pipeline valves. As a rule, a sealed box contains two mechanical switches rated for up to 250 V, which monitor the position of the actuator rod and signal in extreme positions. They are mounted on top of the actuator surface. In the upper part of the limit switch unit there is a two-color hemisphere of the visual indicator. If the connected pipeline valve is closed, then only the red part of the hemisphere with the inscription CLOSED is visible; if open, only the yellow part with the inscription OPEN. This visual indicator is clearly visible from afar, which simplifies the inspection of the equipment, and the color difference between the open and closed positions reduces the likelihood of erroneous perception of information. Thanks to the use of the LSU, it becomes possible to transmit information about the position of pipeline valves (open/closed) to automated control systems, which increases the reliability of the system as a whole and simplifies diagnostics when faults are detected.

The AFC2000 air preparation unit is designed to clean compressed air from droplet moisture and solid particles, remove condensate, automatically maintain the pressure at a given level, supply lubricant from the tank to the compressed air flow to the pneumatic system elements with a large range of throughput from 500 liters/minute to 10,000 liters/minute. The lubricator (oil sprayer) adds oil with a viscosity of 32 mm²/s (=cSt) at 40°C to the pneumatic system for further lubrication of control components - pneumatic cylinders and pneumatic distributors.
