Butterfly valves made of UPVC (unplasticized polyvinyl chloride) is designed to reliably shut off and regulate the flow of aggressive and neutral liquids at moderate pressures and temperatures. Due to its high chemical resistance and corrosion resistance, it is widely used in the chemical industry, water treatment systems and municipal infrastructure.
PA-DA-x double-acting pneumatic actuators use two ports to supply the control medium and create movement in both directions, both to open and close the valve. One port is used to move the piston in one direction and the other port is used to move the piston in the opposite direction.
The limit switch box is designed for visual and electrical signaling of the final positions of the shut-off valve body: ball-check-valve, ball valve or wafer butterfly valve. Mounted on top of the surface of the pneumatic actuator and connected to the drive shaft DIN standard. In a sealed box, as a rule, there are two sensors that monitor the position of the drive shaft and signal in extreme positions. OMRON microswitches, inductive sensors or reed switches are used as sensors.
Pneumatic valves are used for control in pneumatic systems with NAMUR docking surface, for installation of valves through holes in the housing.
