Pressure relief valve Type DV700
The BIERI series WVM-6I consists of direct solenoid operated leakage free seated valves, applicable for high duty cycles. The modular principle of the main components allows for a huge variety of circuit symbols: 2/2-, 3/2-, 3/3-, 4/2-, 4/3- and 4/4-way functions with positive and also negative overlap. Consequently these valves are superior and space-saving alternatives to spool valves which can require additional leackage free shutoff valves.
FeaturesAdvantagesPatented inline arrangement of cone / seat elementsLeakage free (double tight)Pressure compensated design of valve cones, high magnetic force and strong return springSafe and fast switching, bidirectional flow on open shift position and double tight with leakage free tightness in closed positionHardened seat elements (cone and seat)Long operating lifetime and reliabilityZinc nickel coated coils, valve body made of corrosion resistant heat-treatment steelArbitrary position of solenoid coil, replacement of coils without opening of the pressure tight spacesCheck valves and orifices can be integratedHigh corrosion resistancePlate mounted valve with pattern according ISO 4401-03360° turnable and exchangeable plug-in coil
