Product Description

High Quality Hydraulic Overcenter Valve Hydraulic Balance Valve for Crane

Introduction

The hydraulic single over-center valve, often referred to as an over-center or counterbalance valve, stands as a crucial element in hydraulic systems. It adeptly governs the motion of actuators such as cylinders or motors, especially in applications where accurate load management or load retention is vital.

To summarize, the single hydraulic overcentre valve is a cornerstone in hydraulic systems, providing controlled motion and reliable load holding. This ensures safety, stability, and peak efficiency across diverse industrial and mobile equipment applications.

A single overcentre valve's primary role is to deliver precise control of loads influenced by gravitational or inertial forces. These valves guarantee that actuators, including cylinders, operate seamlessly and safely in both directions, preventing unintended drift or runaway movements under load.

Operational Overview at a Glance:

Controlled Movement	As the actuator (such as a cylinder) extends or retracts, the over-center 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 over-center valve increases safety and stability in various hydraulic applications such as lifting, lowering, and holding.
