Description / Abstract:
This International Standard specifies dimensional and
performance requirements for hydraulic screw-to-connect
quick-action couplings designed to be used at pressure of 72 MPa
(720 bar1)) in static conditions as an interface between
a hydraulic power unit and a tool. Typical applications for these
couplings are related to hydraulic jacks, rams, clamping devices,
hand tools, and cylinders.
This International Standard covers two types of such couplings:
the "P" type, which has a poppet valve, and the "S" type, which has
a spherical valve.
1) 1 bar = 100 kPa = 105 Pa = 0,1 MPa; 1Pa = 1
