The VPWI proportional 3-way valve based on the VPPI can be used for all applications where flow control is required. It offers extremely short operating times, a stable valve position and extensive functionality, from setpoint adjustment to an MFC-like function, making the VPWI extremely flexible in use.
The new design of the proportional 3-way valve VPWI with its small footprint allows it to be mounted directly on the system, while the integrated DIN mounting rail also enables installation into a control cabinet. Thanks to the continuous P1 duct, several valves with a compressed air supply on both sides can be installed in series very compactly. The two front-mounted exhaust air and process connections permit installation into the smallest of spaces.
The fully graphic TFT display makes the intuitive menu easy and very flexible to operate. Setpoint adjustment, stroke adaptation, a progressive rising edge or back pressure compensation are only some of the extensive functionalities of the VPWI. The valve stroke can optionally be returned as an actual value in percent or the pressure in port P2 in bar.
The VPWI incorporates two poppet valves and therefore does not have any internal air consumption. The material selection and very low leakage of the valve also make it very suitable for use with inert gases. The VPWI perfectly masters all application areas, whether for single-acting drives or in solutions for blowing air, cooling air and hot air generation or for inert gas applications.
