For the function ..normally closed" with deener-gised pull-type solenoid, and .normally open" with energised push-type solenoid, the differ­ential area poppet piston is held in closed po­sition by a spring and seals leak free from port 2 to 1. If pull-type solenoid is energised respec­tively push-type solenoid deenergised, the poppet piston will open flow passage from 2 to 1 after having reached the opening pressure. In the .normally closed" valve with deenergised solenoid respectively the „nor-mally open" valve with energised solenoid flow passage from 1 to 2 is open when the opening pressure has been reached.

Wandfluh solenoid operated poppet valves are applied where an absolutly leak free closing of the valve is essential like in load holding-, clamping- or gripping functions. These valves are suitable for hazardeous areas in off-shore and shipbuilding applications as well as in the chemical-, oil- and gas industry. The screw-in cartridges are mainly used in mobile or station­ary integrated blocks and in size NG10 flange and sandwich bodies. Cavity tools are availa­ble for machining cartridge cavities (hire or pur­chase). Please refer to the data sheets in reg­ister 2.13.

* Deviating pressure medium - or ambient temperatures are possible for special arrangements after checking and authorisation by a responsible inspector. Measures for the prevention of the exceeding of the admissible solenoid surface - and internal temperatures can be: a good ventilation, low ambient temperatures (for higher pressure medium temperatures), limitation of the maximum possible power supply voltage, a short switching-on duration, installation on large heat dissipating blocks, etc. The responsibility in all cases lies with the operator, resp. with his inspector.
