150101090029A050 One-way valve A4 assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 150101090029A050 check valve A4 assembly is independently developed by SANY and is designed to meet the high-load and complex working conditions of construction machinery. It solves industry pain points such as sealing leakage, valve core jamming, and insensitive opening and closing of traditional check valves. As a “safety guardian” of hydraulic systems, it can effectively prevent oil backflow from damaging core components such as pumps and pipelines. It is a key control component for stable pressure and safe operation of hydraulic systems, with outstanding adaptability and stability, which helps to achieve efficient operation and maintenance of equipment.

Core technical parameters:

– Model: 150101090029A050 Check Valve A4 Assembly
