Poppet valve cartridge M18

Wandfluh has revised the proven poppet valve cartridges and provided them with a more powerful magnetic system. The solenoid coil is now steel-jacketed and accordingly optimised for use in harsh environments. The valve can switch volumes up to 40 l/min at up to 350 bar. In the closed position, the metallically sealing seat closes the valve practically leakage-free. The universally applicable valve has the most common solenoid connections and voltages. It is optionally available with an integrated manual override. 
The solenoid coil, the armature tube, and the valve body are very well protected against corrosion by a zinc-nickel coating (1000h in salt spray test). The direct operated valve of nominal size M18 is available as a 2/2-way function, as normally open or normally closed, with the designation SDSPM22-SDSPM18-AB or SDSPM18-BA and as a 3/2-way function with the designation SDSPM18-FG. Applications are where tight closing of lines is essential, such as, for example, holding a load with a 2/2-way function. The operation of an actuator or the pilot control of the main valve is typical applications for this poppet valve in 3/2-way execution.
