Section Hydraulic Directional Valves: An Introduction

Section hydraulic directional valves, also known as stack valves, are essential components in hydraulic systems, particularly for mobile and industrial applications. These valves are designed to control the flow and direction of hydraulic fluid, enabling precise movement and operation of machinery. Here’s an overview of their performance features, application range, flow and pressure ranges, and control methods:

Performance Features

Modular Design: Sectional valves offer a high degree of flexibility and customization. They can be stacked to create multiple sections, allowing for complex hydraulic circuits to be built according to specific application requirements.

High Flow and Pressure Ratings: These valves are capable of handling high flow rates and pressures, making them suitable for heavy-duty applications. For example, the DCV40 series sectional directional control valve has a rated flow of 40 L/min and a rated pressure of 31.5 MPa.

Versatile Control Options: Sectional valves can be controlled manually, electrically, hydraulically, or through a combination of these methods, providing versatile operation options.

Application Range

Construction Equipment: Used in excavators, loaders, and cranes to control the movement of hydraulic cylinders and motors.

Agricultural Machinery: Applied in tractors and harvesters for hydraulic functions such as lifting and steering.

Industrial Machinery: Utilized in various industrial equipment where precise control of hydraulic fluid flow is required.

Flow and Pressure Ranges

Flow Range: Sectional valves typically handle flow rates ranging from 35 to 700 liters per minute, depending on the specific model and manufacturer.

Pressure Range: The working pressure for these valves can range up to 350 bar, making them suitable for high-pressure hydraulic systems.

Control Methods

Manual Control: Operated directly by a lever or handle, manual control valves are simple and reliable.

Electric Control: Using solenoids to actuate the valve, electric control valves offer precise and responsive operation.

Hydraulic Control: Controlled by hydraulic pressure, these valves are suitable for applications requiring high power and precision.

Electro-hydraulic Control: Combining both electric and hydraulic elements, electro-hydraulic control valves provide precise control and are ideal for complex hydraulic systems.
