AJ-H10B Check Valve
Introduction
A one-way valve, or a check valve, used in hydraulic systems to ensure that oil can only flow in one direction and cut off in the other direction.
There are two types of opening pressures: 0.04MPa and 0.4MPa. The former is generally used in pressure pipelines to prevent reverse oil flow; The latter can generally be used as a back pressure valve.
The inlet and outlet of the plate type one-way valve are on the same bottom plane, and the valve plate is connected to the system pipeline.
Usage conditions:
Medium: mineral oil; Aqueous working fluid
Medium temperature range: mineral oil: -20 ℃~70 ℃; Aqueous working fluid:+10 ℃~54 ℃
Medium viscosity range: 10~350mm2/s
Oil filtration accuracy: ≤ 30 µ m
Rated operating pressure: 31.5MPa
