Product Description

Safety Valve Hydraulic Balance Control Valve for Crane with 320bar

Introduction

A hydraulic single over-center valve, also known as an over-center or counterbalance valve, is a vital component in hydraulic systems. It carefully regulates the movement of actuators, such as cylinders or motors, especially when precise load control and secure load holding are critical.

To summarize, a single hydraulic over-center valve is indispensable for hydraulic systems, ensuring controlled movement and secure load holding. This promotes safety, stability, and optimal efficiency across various industrial and mobile equipment applications.

The main function of a single over-center valve is to provide dynamic control over loads affected by gravitational or inertial forces. These valves ensure that actuators, such as cylinders, operate smoothly and safely in both directions, preventing unintended drifting or runaway movements 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.
