Product Description

High Quality Single Overcenter Valve Hydraulic Balance Valve for Crane 

Introduction

A hydraulic single over-centre valve, also known as an over-centre or counterbalance valve, is an essential component in hydraulic systems. It controls the movement of actuators such as cylinders or motors, particularly in applications where load control or load holding is critical.

In summary, a single hydraulic overcentre valve is essential in hydraulic systems to provide controlled movement and load holding. This ensures safety, stability and efficient operation in a wide range of industrial and mobile equipment applications.

The primary function of a single overcentre valve is to provide dynamic control of loads influenced by gravitational or inertial forces. These valves ensure that actuators, including cylinders, move smoothly and safely in both directions without drifting or running away under load.

Here's a typical operational overview:

Controlled Movement	As the actuator (such as a cylinder) extends or retracts, the overcentre valve allows fluid to flow in the direction of movement, providing unrestricted flow for fast operation.
Load Holding	When the actuator reaches the desired position, the valve moves to a closed or throttled position. This restricts the flow of hydraulic fluid from the actuator's rod end, creating a counterbalance to external forces (such as gravity or a load pushing down). This prevents the actuator from moving unintentionally and maintains the position even when the hydraulic system is not actively supplying pressure.
Safety and Stability	By preventing the actuator from running away under load, the overcentre valve increases safety and stability in various hydraulic applications such as lifting, lowering and holding.
