Advantages of Hydraulic Valves

 
 
01
 

Hydraulic Valves Have a Simple and Compact Structure

Hydraulic valves are small enough to fit into corners and places that are difficult to access. They can fit into your pipeline at almost any point and won't take up extra space once installed.

 
02
 

Smooth and Reliable Hydraulic Transmission

Hydraulic systems offer the silky-smooth fluidity of liquid power transmission, so you can depend on a tight-sealing hydraulic valve for years to come.

 
03
 

Large Output Torque

Hydraulic power means extra power. Having more torque in valve actuation means that hydraulic valves can service fast flow rates and overcome high pressures easily.

 
04
 

Adjustable Output Torque

The output torque can be precisely adjusted by the constant pressure relief valve, including the adjustment of opening and closing torque, which can even be directly reflected by the hydraulic meter.

 
05
 

Convenient Speed Regulation

Regulating the flow rate is another important advantage of hydraulic valves. If your application demands articulate actuation and precise flow regulation, you should consider using hydraulic valves.

Our Best-Selling Hydraulic Valve Types
 
 

Monoblock Control Valves

These are used to control the flow and direction of hydraulic fluid in a hydraulic system. Monoblock valves are available in a variety of configurations, including directional control valves, pressure control valves, flow control valves, and check valves.

 
 
 

Sectional Control Valves

Sectional valve offers multi-function control valve method to solve hydraulic circuit system requirement. The compact construction design is one of strong features for sectional directional control valves include other features, such as low pressure drop, high efficiency.

 
 
 

Solenoid Sectional Diverter Control Valve

A solenoid sectional diverter control valve is a type of hydraulic valve that uses a solenoid to control the flow of hydraulic fluid, directing it to different circuits or actuators within a system. It's a "sectional" valve, meaning it's built from multiple modules or sections, allowing for customization and flexibility in system design.

 

 

Basic Principles of Hydraulic Valve

 

 

Hydraulic valves use actuating mechanisms that open, close, or regulate the valve using hydraulic force. They consist of three main parts: control, power, and actuator. The control part is composed of a pressure control valve, a flow control valve, a directional control valve, and an electrical control system. The power part is composed of a motor or pneumatic motor, hydraulic pump, fuel tank, and other components. It converts the effective power on the rotating shaft of an electric or pneumatic motor into fluid pressure energy that is hydraulically transmitted. There are two kinds of actuators. One is the hydraulic cylinder actuator, which makes reciprocating linear motion. The other is the hydraulic motor actuator, which makes rotary motion.

Main Parts of Hydraulic Valve

Valve body: The main body of the valve, usually made of steel or cast iron, to provide a connection point for the hydraulic pipeline.

 

Control spool: Control valve body moving parts, by opening, closing part of the blocked path to guide the flow of hydraulic fluid.

 

Actuator: The mechanism used to move the spool or lift the spool. It can be

Manual: Lever or handwheel operation.

Mechanical: Operated by a cam or linkage.

Hydraulic: Actuated by another hydraulic fluid.

Pneumatic: Actuated by compressed air.

Electrical: Electromagnetically operated.

 

Seals and o-rings: Ensure that hydraulic fluid does not leak from the valve.

 

Spring: The spring is generally used to return the spool to its initial position after the actuator force has been removed.

 

Uses of Hydraulic Valve
 

Hydraulic valves regulate the flow of fluid through hydraulic systems.

It can be used to switch to required pressure.

It can regulate or restrict the direction of fluid flow.

FAQ

 

Q: What are the advantages of hydraulic valves?

A: 1) Hydraulic valves have a simple and compact structure.
2) Smooth and Reliable Hydraulic Transmission.
3) Large Output Torque.
4) Adjustable Output Torque.
5) Convenient Speed Regulation.
6) Performance in Power Failure Situations.

Q: What is a hydraulic valve used for?

A: Hydraulic valves are pivotal mechanical components designed to regulate the flow of hydraulic fluid in systems often exposed to high pressures, typically starting at 200 bar and possibly extending up to 700 bar or more. These valves need to be constructed from materials strong enough to withstand such pressures.

Q: What are the three types of hydraulic valves?

A: Hydraulic valves are available with many different mounting styles, such as mounting in pipelines, with threaded connection as cartridge valves, subplate mounting or flanged mounting. Hydraulic valves are subdivided into three main categories: directional control valves, pressure control valves and flow control valves.

Q: Are hydraulic valves safe?

A: At its core, a hydraulic valve is designed to do one or a combination of three primary tasks: allow fluid flow, prevent fluid flow, or partially allow fluid flow. This simple but vital operation is what makes hydraulic systems flexible, responsive, and safe.
