This International Standard gives complete general
and dimensional specifications for four-screw, one-
piece square-flange connections for use at pressures
of 25 MPa and 40 MPa (250 bar) and 400 bar).
For flange connections, a design factor of 2,5 is valid,
not including weld joints, for which special in-
structions exist.
This International Standard also specifies the dimen-
sions of the seals to be used, as well as the grooves
to house the seals.
These connections are intended for application in hy-
draulic systems, on industrial and commercial prod-
ucts, where it is desired to avoid the use of threaded
connections.
Surges of pressure higher than the nominal ratings
will reduce the ability of the flange connections to re-
tain the hydraulic fluid and this should be taken into
account in the design of the hydraulic system.
