Product Description

Yikde Single Hydraulic Overcenter Control Valve Hydraulic Balance Valve

Introduction

In hydraulic systems, particularly those found in construction machinery and other mechanical systems affected by gravity, balance valves play a critical role. 

These valves are designed with a hydraulic circuit that ensures the return oil back pressure is balanced with the changing load. This balance is crucial for allowing the load to stop reliably at predetermined positions and controlling the movement's balance when the load drops. By doing so, they prevent structural and hydraulic pipeline damage caused by excessive drops in load.

In essence, balance valves contribute significantly to the safety and efficiency of hydraulic systems, especially in scenarios where machinery is lowered by gravity. They ensure smooth operation while protecting the equipment and surrounding infrastructure from potential harm.

Working Principle

How Does It Work?

A hydraulic balance valve operates by sensing pressure differentials in a hydraulic system and adjusting accordingly. Here is a simplified explanation of its working principle:

• Pressure Sensing: The valve contains internal mechanisms that detect changes in pressure across its inlet and outlet. These mechanisms can be pilot-operated or mechanically actuated, depending on the design.

• Flow Regulation: When pressure changes, the valve adjusts its internal components (like springs or pistons) to alter the flow path. This can involve changing the orifice size, adjusting a spool position, or opening/closing a flow path, depending on the design.

• Balancing Effect: By adjusting the flow based on pressure changes, the valve ensures that fluid is distributed evenly throughout the system. This balanced distribution reduces the risk of pressure spikes or fluid starvation, promoting smooth operation.
