Product Description

China Hydraulic Balance Valve Counterbalance Valve for Crane

Introduction

Without a balance valve, the hydraulic system may experience issues such as excessive pressure, uneven load distribution, and unstable movement. This can lead to reduced efficiency, increased wear and tear on components, and potential safety hazards.The balance valve works by maintaining a consistent pressure in the hydraulic system by adjusting the flow rate of oil returning to the reservoir. It does this by creating a pressure drop across an orifice or restrictor. When the load on the system increases, more oil flows through the restrictor, increasing back pressure and preventing excessive loads on individual components.

In construction machinery and other gravity-lowered systems where loads vary frequently, such as cranes or excavators, having a balance valve is crucial. These machines often operate at different angles or have varying loads depending on their position or activity. The balance valve ensures that regardless of these factors, there is always enough back pressure to prevent overloading while maintaining smooth operation.

Additionally, using a balance valve helps reduce energy consumption in hydraulic systems. By regulating the return oil flow according to load demands instead of constantly circulating it at maximum pressure levels, unnecessary power wastage can be avoided.

Overall, balance valves are essential for maintaining proper functioning in hydraulic systems used in construction machinery and other gravity-lowered mechanical systems. They provide stability and reliability while ensuring safe operations by regulating back pressure based on changing load requirements.
