Proportional spool valve NG6 with enhanced corrosion protection

The proven flange spool valves for the modular valve construction have been extended with an execution for use in very corrosive environments. In the "K8" execution, all external metal parts of the valve are completely coated with zinc-nickel, resulting in significantly higher corrosion protection (800 h in the salt spray test according to ISO 9227). The valve can be used up to a pressure of 350...

Spool valve Ex-protection in stainless execution

Wandfluh has extended the proven spool valves for the modular valve construction with a version for use in highly corrosive environments. The valve can control volume flows up to 50 l/min with up to 350 bar and is available as a 2-way or 3-way function. All external parts such as valve body, cover, solenoid coil etc. are made of stainless and acid-resistant steel (AISI 316L). The armature tube...

Proportional pressure reducing valve with integrated DSV electronics

The pressure reducing valve with integrated electronics is now available with an optional 7-pole connector plug, which corresponds to the connection standard used in many places. The valve finely and precisely controls the output pressure in proportion to the specified target pressure and this in various pressure ranges up to a pressure of 350 bar with a max. flow of 40 l/min. The minimum...

PD3 control electronics for proportional valves

The newly developed PD3 electronics can be mounted directly on a solenoid coil (see picture) or connected to a standard solenoid coil with a cable. It offers a very simple and cost-effective way to directly control proportional valves and parameterising them via a standardised IO-Link interface, as well as transmitting command value and diagnostic data. Furthermore, thanks to the IO-Link...
