General Description
Series C18DB 2/2 way seat valves with cartridge
design according to ISO 7368 are preferably used
where opening and closing should be controlled by
pilot pressure only, independent of the pressure in the
main ports.
Series C18DB is offered as hydraulically controlled
valve (C18DB107), with additional stroke limiter
(C18DBN112) and with the mounting pattern for a pilot
valve (C18DB121).
Features
ā€¢
Cavity and mounting pattern acc. to DIN ISO 7368.
ā€¢
Active design with separate control areas.
ā€¢
Sealing between control surfaces and connection B.
ā€¢
Up to 5 sizes:
- C18DB107 - 5 sizes NG25 up to NG63
- C18DBN112 - 3 sizes NG25 up to NG40
- C18DB121 - 2 sizes NG32 up to NG40
