Modular check valves type HR, KR, JPR
direct or pilot operated, ISO 4401 sizes 06, 10, 16 and 25
Table D180-8/E
HR, KR are check valves available as
direct or pilot operated models.
JPR are pilot operated check valves.
Optional versions with decompression
are available on request for some
models of KR.
HR-0 = ISO 4401 size 06 interface: flow
up to 60 l/min, pressure up to 350 bar.
KR-0= ISO 4401 size 10 interface: flow
up to 120 l/min, pressure up to 315 bar.
JPR-2 = ISO 4401 size 16 interface: flow
up to 200 l/min, pressure up to 350 bar.
JPR-3 = ISO 4401 size 25 interface: flow
up to 300 l/min, pressure up to 350 bar.
Valves are designed to operate in
hydraulic systems with hydraulic mine-
ral oil or synthetic fluid having similar
lubricating characteristics.
HR-0
Modular check valve, size:
HR-0 = 06
KR-0 = 10
JPR-2 = 16
JPR-3 = 25
Spring cracking pressure
for HR and KR for JPR
– = 0,5 bar (std.) /4 = 4 bar – = 0,5 bar
/2 = 2 bar /8 = 8 bar
Options (only for KR-012, -013, -014):
/D = with decompression (only with cracking pressure
standard = 1 bar)

The pilote pressure applied through ports A or B opens the valve acting on ports B and A, respectively.
The minimum pilot pressure is a function of the area ratio, see the following table.
