Leak-free closure in one direction
The check valves VJO1 are developed to be built
directly into the lines of the hydraulic circuits. Their
features designate them for all applications, where tight
closure in one direction and small dimensions are
required. The valve is provided with holes for a
mounting mandrel. The shut-off edge (3) of the valve is
engineered in the housing (1) and the shut-off function is
accomplished by the ball (2) which is pushed onto the
seat by spring (4). Sealing of the valve body (1) in the
mounting cavity is provided by the sealing ring (5).
During the assembly, the valve has to be secured
against loosening by means of a suitable glue or cement
(Loctite, etc.).
