Product Description

Yikde Single Overcenter Valve Hydraulic Balance Valve for Crane

Introduction

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

In summary, a hydraulic single over-center valve is critical 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 over-center 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	When the actuator (such as a cylinder) extends or retracts, the over-center valve allows fluid flow in the direction of movement, providing unrestricted flow to facilitate quick operation.
Load Holding	Once the actuator reaches the desired position, the valve shifts to a closed or restricted position. This restricts the flow of hydraulic fluid from the actuator's rod end, creating a counterbalance against external forces (like 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 over-center valve enhances safety and stability in various hydraulic applications, such as lifting, lowering, and holding operations.
