The Wandfluh poppet valve cartridges have been extended with a very small actuation power. The valve can switch flow rates up to 10 l/min at up to 350 bar with an electrical power of 6 Watt. With the option of integrated electronics, a 4 Watt holding power can be achieved. The valve is controlled by a solenoid certified for use in explosion hazard areas. The valve body, the solenoid coil and the armature tube are very well protected against corrosion by their zinc-nickel coating.
The direct operated valve with the cavity thread diameter M22 according to ISO 7789 is available as a 3/2-way function with the designation SLYPM22-FG_L6. It is used wherever electrical power is limited. This may be due to the maximum available current or limited capacity, e.g. of a battery in self-sufficient systems. The application is where loads have to be held seat tight in explosion-hazard areas or where actuator controls have to function leakage-free.
