ON/OFF Solenoids type F HM G + F HT S


The actuators for ON/OFF valves type F HM G + F HT S (previous designation G HP Y) are designed according to the modular principle and consist of a magnet body type F HM G, and a tube type F HT S. The data sheet shows the construction method and exemplary technical data on the basis of exemplary designs. The grading of the sizes is matched to the actuation of valves of nominal sizes NG4, NG6 and NG10.  

The solenoid body is fixed with a fastening nut on the tube and can be removed or replaced without opening the hydraulic circuit.

The modular design makes it possible to combine the tube also with a solenoid body type F MM E, which has approvals according to ATEX and IECEx for operation in potentially explosive atmospheres. Please refer to the data sheet of the devices F MM E + F HT S.
