Precise quantity control and comprehensive functionalities
The proportional 3-way valve VPWI is based on VPPI and can be used for all applications that require flow control. It offers extremely short operating times, a stable valve position and extensive functionality, from setpoint adjustment to an MFC-like function This makes the VPWI extremely flexible in use.
Compact and versatile
The new design of the proportional 3-way valve VPWI has a small footprint, so it can be mounted directly on the system, while the integrated H-rail also enables it to be installed in a control cabinet. A very compact series installation of several valves with a compressed air supply on both sides is also possible thanks to the continues P1 duct. The two exhaust air and process connections at the front facilitate installation into the smallest of spaces.
Innovative and individual
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.
Wide range of applications
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.
