Proportional screw-in cartridges with slip-on coil
Wandfluh is offering the proportional screw-in valves with slip-on coil. Due to the exchangeable coil, the logistics can be significantly simplified, because the solenoid coil can also be retrofitted. With the different variants, the proportional screw-in cartridges have become a very flexible system. Different plug - and voltage variants are available ex stock and are complemented with respect to individual adaptations with the customary Wandfluh flexibility. In addition, the performance of the valves has been enhanced by the improved solenoid coil. Therefore also ambient temperatures of up to 70 °C can be accepted without any loss of performance. With the improvement of the corrosion protection of the solenoid coil, the valves - depending on the version - achieve a salt-spray resistance of over 500h.
