152300000146A003 Check valve Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 152300000146A003 check valve is a core directional control component in the hydraulic system of Sany construction machinery. Specifically designed for Sany excavators and loaders, it is compatible with SY205, SY215, and SY385 series models and similar hydraulic systems, earning it the reputation of being the “one-way gatekeeper” of the hydraulic system. Its core function is to control the unidirectional flow of hydraulic media, preventing backflow and avoiding damage to core components such as the pump body and valve core caused by backflow. It also balances the pressure of the hydraulic system. Through precision manufacturing and stringent quality control, it effectively solves the pain points of traditional check valves, such as opening and closing difficulties, poor sealing, and insufficient high-pressure resistance, reducing failure and maintenance costs, making it a preferred maintenance accessory.
This product adopts a dedicated SANY adapter design with a dimensional error within ±0.2mm. The mounting hole positions conform to national standards and can be connected by thread or plate. It can be quickly assembled and replaced without special tools. The structure has been mechanically optimized, the valve disc is wear-resistant and can withstand a nominal pressure of 31.5MPa. It has excellent vibration and shock resistance, which can avoid valve disc wear and valve body cracking, suppress water hammer impact, reduce unplanned downtime losses, and is suitable for harsh working conditions.

Core technical parameters:

– Product Model: 152300000146A003
– Compatible brands: Sany and similar compatible construction machinery
– Compatible models: SANY SY205, SY215, SY385 series excavators and loaders
– Implementation standards: JB/T 10364-2014, GB/T 10869-2008 (Complies with national and industry standards, quality is guaranteed)
– Nominal pressure: 31.5MPa (High pressure resistant, suitable for the high pressure requirements of hydraulic systems in engineering machinery)
– Opening pressure: 0.03~0.05MPa (sensitive opening and closing, suitable for low-pressure start-up requirements)
– Rated flow rate: 50L/min (smooth flow, low flow resistance, does not affect the power output of the hydraulic system)
– Main body material: High-strength stainless steel (resistant to high pressure, corrosion, and vibration, suitable for complex working conditions)
– Sealing material: Fluororubber (FKM) (tight seal, oil and aging resistant, no media leakage)
– Operating temperature: -40℃~100℃ (wide temperature range, adaptable to various regions and working conditions)
– Dimensional tolerance: ±0.2mm (precise specifications, compatible with SANY hydraulic circuit installation)

– Suitable for: Hydraulic circuits of equipment such as Sany excavators and loaders, used to prevent backflow of media, protect system components, and for routine maintenance and fault replacement.
The 152300000146A003 check valve undergoes multiple tests for continuity, sealing, pressure resistance, and vibration resistance, meeting SANY’s parts standards. It is easy to install and can be directly replaced, significantly improving operation and maintenance efficiency, reducing media backflow, component wear and downtime losses, and lowering overall operation and maintenance costs.
