Product Description

China Hydraulic Control Valve Vbcd-G38-De Hydraulic Counterbalance Valve

Introduction

The balance valve is a crucial component in hydraulic systems, particularly in construction machinery and similar mechanical applications where loads are controlled by gravity. Its primary function is to maintain hydraulic balance within the system by adjusting the return oil back pressure in response to changes in the load. This balance ensures that the load can come to a halt reliably at a specific position and allows for controlled movement during descent.

In summary, the balance valve plays a vital role in hydraulic systems by facilitating precise control over load movement, preventing damage due to excessive drop, and enhancing the overall safety and efficiency of construction machinery and mechanical equipment.

Working Principle

How They Work:

Pressure Regulation: These valves regulate hydraulic pressure within a defined range. They allow fluid to flow in one direction with minimal resistance while providing controlled resistance in the opposite direction, based on preset pressure settings.

Check Valve Mechanism: The check valve allows fluid to flow freely when the system is pressurized in one direction, ensuring that actuators can move freely. When the pressure is reversed, the check valve blocks the flow, maintaining the position of the load.

Pilot Pressure Control: Overcenter valves typically use a pilot-operated system. When pilot pressure is applied, the valve opens to release the load, allowing controlled movement. This design ensures smooth transitions and prevents sudden movements.
