actuated by fluid ( ; fluid-actuated check valves F16K15/00; fluid-actuated safety valves F16K17/00)

Introduced: September 1968

Title

Titles differ between systems:

IPC: actuated by fluid

CPC: actuated by fluid ( ; fluid-actuated check valves F16K15/00; fluid-actuated safety valves F16K17/00)

Full titles differ between systems:

IPC:

Operating means; Releasing devices > actuated by fluid

CPC:

Operating means; Releasing devices > actuated by fluid ( ; fluid-actuated check valves F16K15/00; fluid-actuated safety valves F16K17/00)

IPC and CPC are identically structured here. All 7 subcodes exist in both systems.

6 shared codes have differing titles between IPC and CPC.
