The ball valve is used as a shut-off valve in heat supply systems, 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.), non-aggressive to the materials of the valve.
Pneumatic actuators PA-DA are designed to automate the process of controlling industrial shut-off valves - valves, ball valves. Pneumatic actuators DNOVA are designed for use both indoors and outdoors. All internal and external parts have an anti-corrosion coating.
The DNOVA APL-510N-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.
