Solenoid valve for gases and solid-free liquids. The valve seat is sealed by a rubber diaphragm.
Benefit from the advantages of the 40 series with threaded connection if you ensure that there is a minimum pressure difference between the inlet and outlet. The specification of the min. pressure difference can be found in the data sheets and precedes the max. possible pressure difference.
Valve is sensor-ready, configurable with end position detection as option -6H or for retrofitting.
