Description

Butterfly valve Elephant is designed for use as shut-off or regulating valves for flow control in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
DA pneumatic actuators are designed to automate the process of controlling industrial shut-off valves - gates, ball valves. Elephant pneumatic actuators are designed for operation both indoors and outdoors. All internal and external parts are anticorrosive coated.
Elephant 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 valve body. In a sealed box, as a rule, there are two mechanical switches designed for voltage up to 250 V, which monitor the position of the actuator stem and signalize 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 visual indicator hemisphere. If the connected pipe fitting is closed, only the red part of the hemisphere labeled CLOSED is visible; if it is open, only the yellow part labeled OPEN is visible. This visual indicator is clearly visible from a distance, which simplifies the inspection of the equipment, and the color difference between the open and closed position reduces the probability of misinterpretation of information.
