803278453 Counterbalance Valve XCMG XDE130 Electric driving dump truck spare parts

The 803278453 counterbalance valve can solve problems such as load slippage, inconsistent lifting speed, pressure holding and release, valve core jamming, valve port oil leakage, pressure regulation failure, abnormal opening and closing noise, load slump, reversing vibration, and balance failure. It is suitable for replacing old balance valves, crane hydraulic maintenance, original equipment manufacturer (OEM) parts, lifting hydraulic circuit renovation, and repairing load-bearing anti-fall faults. Featuring a forged alloy valve body, pressure regulating and sealing valve core, and damping pressure stabilization structure, it provides smooth speed limiting, self-locking anti-fall, high-pressure anti-leakage, oil resistance, and wear resistance, making it suitable for hydraulic conditions in engineering machinery lifting, jacking, load suspension, and uniform speed lifting.

Core technical parameters:

– Product Model: 803278453
– Product Name: Counterbalance Valve
– Material specifications: High-pressure thickened alloy valve body, valve seat hardened by quenching, high-frequency negative start-up and closing, not easy to wear and leak.
– Processing technology: Precision boring of original oil circuit holes, matching and grinding of valve cores, and direct installation and adaptation of original vehicle hydraulic oil circuit ports without damage.
– Performance and working condition adaptability: Rated load and pressure bearing capacity meets standards, damping speed limiting and pressure holding, and is compatible with the whole machine’s lifting load balance hydraulic control system.
– Structural features: Integrated damping balance structure with built-in load-bearing anti-fall lock to prevent slippage due to self-weight and loss of control during lifting.

This product has undergone load testing, speed limiting adjustment, high-pressure leak detection, and original vehicle port compatibility with original factory quality inspection, meeting original factory installation standards and ready to use immediately after installation. It balances oil pressure in the hydraulic circuit, limits descent speed, and locks the load, ensuring smooth lifting and lowering of equipment under load, and providing safe and controllable operation.
