The white steel valve block is used in the electro-hydraulic servo control system and is a subsystem of one of the eight major systems in the TRT device.

The main manifestations of valve block failure include excessive clearance between the hole and the rod, dynamic seal wear, console shoulder wear, and cavitation. Dalian precision parts processing manufacturers have summarized the following three forms:

(1) Performance degradation: accounting for approximately 15% of failures;

(2) Performance degradation: accounting for about 70% of failures, it is divided into corrosion and mechanical wear, and mechanical wear can be further divided into wear, aging, and adhesive damage;

(3) Accidents: accounting for approximately 15% of failures.

The two main reasons for valve block failure are:

(1) The cleanliness of the oil is insufficient;

(2) The system enters the air.
