AAK Hydraulic Cartridge Relief Valve 0 Blockage 3 Advantages

Halian, from Sweden, has been engaged in the procurement of hydraulic
components for 5 years. She began to purchase hydraulic cartridge valves from
Ningbo last year, and was upset by the first purchase for a hydraulic cartridge
relief valve. At the beginning of last year, their hydraulic power unit failed
due to the blockage of the hydraulic cartridge relief valve she purchased from
Ningbo. The original hydraulic cartridge relief valve manufacturer reported
that the hydraulic oil was not clean, but after replacement, the old problem
occurred again in 5 months. Halian thought that the manufacturing quality of
the original hydraulic cartridge relief valve was not up to standard, so she
contacted a new hydraulic cartridge relief valve manufacturer.

Halian found AAK in B2B and left a message: Can AAK solve the problem of
hydraulic cartridge relief valve blockage? After communication, it was learned
that the hydraulic cartridge relief valve she purchased from the cartridge
valve manufacturer in Ningbo was easily blocked. According to the hydraulic
cartridge relief valve samples from the original factory, there are damping
holes, and there are elongated holes in the valve body, which are objectively
easy to block. Can we remove damping holes and elongated holes? According to
this idea, we fed back the plan to Halian. After 40 days, AAK sent 20 samples
of hydraulic cartridge relief valves.

Last week, Halian informed us via email that AAK hydraulic cartridge relief
valve was installed on the equipment, and it has been 8 months since then.
There is no blockage and no customer complaint. AAK hydraulic cartridge relief
valve removes the damping hole and slender hole in the original structure,
increases the flow area, improves the flow passage port, and uses conical
spring. Such hydraulic cartridge relief valve has 3 advantages: stable opening,
short unloading time and small power loss.

1. AAK hydraulic cartridge relief valve seat is a cylinder with one end open
and one end closed, and the open end has external thread, and the closed end of
the valve seat has external hexagonal head structure. Two springs and spring
covers are installed in the valve seat in sequence, and the first spring is a
conical spring with large end upward to ensure stable opening.

2. The upper end of the valve rod of the hydraulic cartridge relief valve is
fixedly connected to the spring cover and has screws. The middle of the spring
cover has a downward protruding rod-shaped body, and the second spring is
sleeved on the rod-shaped body. The lower end of the valve rod has an overflow
valve spool, and the lower end of the second spring is installed in the spring
seat.

3. The oil replenishing valve spool with overflow valve port is set under the
spring seat. There is an oil port between the oil replenishing valve spool and
the spring seat. The valve rod passes through the overflow valve port. The oil
replenishing valve spool and spring seat are in an integral structure. The oil
replenishing valve spool has a ball sealing surface, and the overflow valve
spool has a conical sealing surface.

AAK hydraulic cartridge relief valve is non-clogged and has 3 advantages. You
