Product description
Electromagnetically operated 2/2 directional water valves according to this standard are poppet valves with hydraulic positive stop damping, in which a diaphragm blocks the flow. The valves are actuated by a solenoid, the force of which is supported by the differential pressure between the valve inlet and the valve outlet (Δpmin = 0.1 bar).

Note on the EMC Directive:
A suitable electrical circuitry of the valves must ensure that the limit values of the harmonized standards EN 50081-1 and EN 50082-1 are adhered to and that Directive 89/336/EEC (electromagnetic compatibility) is complied with.
Notice regarding the acceptance classification:
Solenoid according to UL and CSA standard.

Mounting
Notes on the installation:
- Make sure that there is sufficient clearance around the valve. This simplifies checks during operation and maintenance work.
- The valve can heat up during operation. Never paint the solenoid coil and the housing of the solenoid. Never cover the valve with heat insulation material.
- Fluids may only be directed through the valve in the specified direction of flow. An arrow on the valve housing shows the direction of flow. A reversal of the direction of flow must be prevented by taking appropriate measures, e.g. installation of check valves.
Note!
The direction of flow indicated on the valve must be adhered to in order that the valve can perform its intended function.
Pipes must be connected to the valve stress-free and vibration-free.
After mounting, check the installation for leakage and function.
Maintenance, inspection and assembly work may only be carried out by authorized and qualified specialist personnel. Gener-ally, work on the solenoid valve may only be carried out when the system is depressurized and has cooled down. The solenoid must be disconnected from the power supply. Preventive maintenance is recommended in dependence on the operating con-ditions and in the case of perceivable changes in the switching times. The operator is responsible for determining reasonable testing and maintenance intervals depending on the operating conditions of the valve. Sediments, dirt, aged or worn out seals can lead to malfunction. The seals of solenoids must be included in the maintenance schedule to ensure that the specified type of protection is maintained.
Electrical connections:
- Work on electrical connections may only be carried out by specialists
- Before carrying out work on electrical parts, disconnect the power supply
- After having connected the circular plug-in connection M12 x 1 fasten it by means of screws
- Only plug the circular plug-in connection M12 x 1 when it is disconnected from the power supply
- Do not overload contacts (see technical data)
- In the case of inductive loads, provide suppressor circuit!
