Solenoid actuated valves

series K with rotatable coil for temperatures from -40 to +80°C

Indirectly operated valve of the K series, which has not only a large flow rate, a long service life but also better availability. The basic feature of this valve is the possibility of use at temperatures from -40 to +80°C. The valves can be used separately or mounted on a base plate as a group assembly. The connector is supplied only with a cable and must be ordered separately. The connector connection to the coil complies with the DIN 72585 standard, used in the automotive industry.

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.

Technical information

Manifold assembly

Manifolds for K series valves are supplied separately and it is necessary to use one pair of end plates, which are also used as manifolds for 2 valves, and requested number of middle plates (1 plate for 1 valve) to create the complete manifold assembly. It is possible to add other positions to the assembly at any time, just remove the end plate and add additional middle plates. If it is necessary to create a reserve during assembly, it is recommended to use a blank station plate, which can be easily replaced by valve. Max. number of valves in one maifold is 10. Any valve series K may be used for manifold assembly (it doesn‘t matter if valve is single or double solenoid actuated or air actuated). But it is necessary to use adaptor, which must be mounted between valve and manifold. Valves mounted on manifold could be unmounted separately by unscrew of 2 bolts, which are accessible from top side (side with ports 2 and 4 of valves).

Assembly procedure:

1)	On the middle plate, check that the sealing rings in the recesses are seated correctly. Place the middle plate on the end plate pins and secure with two countersunk screws.
2)	Repeat the procedure with the other middle plates.
3)	On the other end plate, check that the sealing rings are seated correctly in the recesses. Place the end plate on the pins of the middle plate and secure with two countersunk screws.
4)	Mount the adapter on the inlet and exhaust side (ports 1,3,5) on the valve using two M4x10 screws. Make sure that the sealing rings are fitted correctly in the recesses.
5)	Mount the valve with the adapter using two M3x12 screws in the required position on the manifold. Make sure that the sealing rings are fitted correctly in the recesses.
6)	Fasten the manifold with valves with all four holes øE.
