Solenoid actuated valves

series K with rotatable coil

A new type of solenoid pilot actuated valve, which offers not only a large flow rate, high durability but also better availability. Valves can be used as standalone or they can be mounted on manifolds. They can replace L1 and L2 series valves because they have the same connection dimensions, unlike the L1&L2 series, the coil can be rotated in the desired direction. Connector and coil are included in delivery.

Valves series K contains spool and sleeve assembly, which guarantee long lifetime of valve.

We make the spool and sleeve assembly from hardened stainless steel. The technical interest is that thanks to the precise grinding and honing of both parts, such accuracy is achieved that the spool in the sleeve moves on the air cushion. This essentially eliminates possible wear and at the same time can be moved very easily and very quickly with the piston. The clearance is so small that there are no leaks even without a seal.
