The mainly frequent types of hydraulic valves

Table of Contents

In the hydraulic market, you can find different types of hydraulic products from different manufacturers, designed for different tasks in different applications. All the best and proper workable products are available at the And the user can find the best valves on the metkoff. Some hydraulic systems require a separate valve, while more complex hydraulic systems may use a combination of valves to perform their function. Below we highlight some of the most commonly used valves to show how their roles differ.

Types of hydraulic valves

The Hydraulic valves are available in a wide variety of styles, including many common to other valve types such as ball, butterfly, bypass, check, needle, and changeover, and control, pilot operated, proportional and directional.

Directional Control Valves

Directional Spool Valves As the name suggests directional control valves are used to direct the flow of fluid through a system. These valves can control the start, stop, pause, and reversal of the flow of the working medium under pressure. For this reason, they also called changeover valves. The valve function is determined by the number of working ports and the number of spool positions. The directional control valve has at least two-spool positions and two working ports.

The most common directional control valve is a 4/3-way valve, which means the valve has four service ports and three spool positions. A 2-way control valve is the simplest directional manage valve that has two ports called inlet and outlet. The 3-way control valve has 3 working ports called inlet, outlet, and outlet. They used in single-acting cylinders, and the third working port can block the flow of all ports.

Hydraulic pressure control valves

Pressure control valves are the most common pressure control valves. These include relief, pressure reducing, sequential, and counterweight and relief valves. The hydraulic pressure regulating valve plays a vital role in preventing pipe or tubing leaks and bursts. Pressure control valves regulate the pressure of the fluid flowing through the pipe or tubing to relieve excess pressure. These valves maintain pressure manually entered by the operator.

Hydraulic flow control valves

The purpose of flow control in a hydraulic system is to control speed. Flow control valves control the speed of the actuator by adjusting the flow rate. The flow rate also determines the rate at which energy transferred at any given system pressure.

Flow control valves used to control and regulate the flow of a liquid or gas in a system. These valves can optimize the performance of your hydraulic system. Flow control valves will monitor and regulate pressure fluctuations in the system and prevent flow to system components.

Why valves are used in hydraulic systems

In a hydraulic system, they have specific roles that they are, control valves capable of controlling the operation of actuators. These valves will also regulate pressure by controlling oil flow. Some valves have multiple functions and are very useful, such as hydraulic proportional valves.
