For the 450bar pressure resistant and abrasion free hydraulic relief valve, only HAWE and AAK have b

Gonzalo comes from Spain and has been purchasing hydraulic valves from Chinese manufacturers for 3 years. At the beginning of last year, they developed hydraulic gantry shears and needed to purchase hydraulic cartridge relief valves. 6 months after the equipment was sold, the customer complained that the hydraulic gantry shear was weak. During after sales service, the valve spool of the hydraulic relief valve was found to be worn and could only be replaced. The original manufacturer fed back that the service life of the hydraulic relief valve under 450bar high-pressure working condition was normal for 6 months.

In the subdivision field of high pressure resistance, AAK hydraulic valve manufacturing quality benchmark is HAWE, because HAWE is the No 1 of this field. We mainly focus on 3 points. It may be difficult to find the second one, from more than 200 hydraulic valve manufacturers in Ningbo.
