Hydraulic Overcenter Valve Hudraulic Fittings Balance Valve
A hydraulic balance valve is a type of control valve that automatically adjusts the flow rate or pressure in a hydraulic system. It helps ensure consistent fluid flow and pressure across varying loads and operational conditions. The valve can compensate for changes in pressure, maintaining a balanced flow, and preventing imbalances that could cause equipment failure or safety risks.
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.

How They Work:
1. 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.
2. 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.
3. 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.
There are many kinds of balance valves, including manual balance valves, electric balance valves, self-balancevalves, counterweight balance valves and so on. Each balance valve has its unique functions and advantages, so it needs to be selected according to different use scenarios. For the balance valve on mechanical equipment, it is usually necessary to consider its mechanical size and connection mode, and determine the required flow adjustment range and control accuracy.
