Active 2/2 way monitored seat valves with cartridge de-

sign according to ISO 7368 are preferably used for safety

circuits: mainly for safety guards, mould form tools and

locking mechanisms for presses and injection moulding

machines. Pilot pressure actively opens and closes the

main poppet - independently of the pressure in the main

ports.

Features

• German trade association certiﬁcate, No. 00 078

• Cavity and mounting pattern acc. to ISO 7368

• Monitored closed position

• Inductive switch CE conform

• Active design with separate control surfaces

• Sealing between control surfaces and connection B

• 5 sizes NG25 up to NG63
