AAK hydraulic relief valve with 5 steps sand cleaning method is not blocked

AAK unique 5 steps sand cleaning method replaces the traditional method
commonly used by peers, and completely solves the problem of valve stuck or
filter blockage of hydraulic relief valves caused by hidden danger in sand
cleaning. The American customer placed an order for the hydraulic relief valves
to AAK 3 days after the test run.

Most of the bodies of the hydraulic relief valves are made of nodular iron,
vermicular iron and gray iron and cast by sand turning with resin sand as the
modeling medium. Therefore, there is sticky sand in the casting, which is easy
to cause valve jamming and filter blockage. Most of the common sand cleaning
methods of hydraulic relief valves in the same industry are shot blasting and
electrochemical sand cleaning. These methods have limitations and are not
conducive to the stability of hydraulic relief valves.

Gabriel is a purchaser of a hydraulic company in the United States. In previous
years, he purchased the hydraulic relief valves in the United States. Recently,
there is an order for hydraulic relief valves. The production of the original
domestic manufacturer is full schedule, while the other hydraulic relief valve
manufacturers dislike the small quantity and are unwilling to accept the order.
The company asked him to check with Chinese hydraulic relief valve
manufacturers. Among several hydraulic relief valve manufacturers recommended
by his colleagues, Gabriel chose 3 of them to send samples after a round of
comparison. After 20 days, the samples of these 3 hydraulic relief valve
manufacturers were generally stable and prone to valve jamming or filter
blockage. The root cause was the incomplete sand cleaning process of the
hydraulic relief valves.

When browsing B2B websites, Gabriel saw that AAK website www.aakindustry.com
introduced the 5 steps sand cleaning method of hydraulic relief valves. He left
a message on our website: Can AAK make the hydraulic relief valves not stuck or
the filter not blocked? We replied him directly: AAK hydraulic relief valves
with 5 steps sand cleaning method have been recognized by German customers. You
are welcome to try the order. Gabriel subconsciously approved AAK hydraulic
relief valves but was still some concerned because of no cooperation before, so
he asked for samples to test first. According to the draft of hydraulic relief
valves sent by him, we sent samples in 2 weeks. Gabriel issued official PO on
the 3rd day after receiving the hydraulic relief valve samples for
commissioning, and requested that the bulk goods to be 100% sand cleaned
thoroughly.

AAK adopts more efficient sand cleaning method and has its own unique 5 steps
sand cleaning method for small and complex castings, namely: Artificial aging -
Pickling - Rinsing - Rust prevention - Ultrasonic cleaning. Artificial aging is
used to reduce the binding force between the casting and sand, acid pickling is
used to remove the oxide skin at the joint between the sand and the casting, so
as to peel the sand off the casting, and then the explosion of compressed air
during ultrasonic cleaning is used to make the sand fall off, so as to achieve
the purpose of 100% sand cleaning. Gabriel issued the PO in 3 days after
receiving AAK hydraulic relief valves for testing. This is a witness of AAK
unique sand cleaning methods.

AAK hydraulic relief valves do not block the valve or filter, which is due to
AAK unique 5 steps sand cleaning method. You can also have a small try.
