2. Technical data
Matters needing attention when choosing working fluid
Working pressure range-inlet side
Absolute pressure of S port (inlet)
Pabs min 0.08Mpa
Pabs min 3Mpa
Working pressure range-outlet side
Pressure at port B
Rated pressure PN 28Mpa
Peak pressure Pmax 35Mpa
Intermittent work when the load time is 10%, the pressure can reach 31.5Mpa
Case drain pressure
The maximum allowable pressure of leaking oil (L, L1 port): the highest can be higher than the inlet pressure of S port by 0.05Mpa, but not higher than 0.2Mpa absolute pressure.
Flow direction: S to B
