About Hydraulic Valves

Hydraulic valves are important as they help control the movement of any liquid particularly, oil, in the system. Selecting the most suitable valve(s) is essential to any hydraulic system. It arrives in different sizes and types based on the pressure of the system as nicely as the flow rate.

3 Main Classifications of Hydraulic Valves

There are 3 main classifications of hydraulic - directional, stress and movement control. Directional are used to manage the fluid's direction from the begin to the end. Stress valves however are used when a specific stress degree is required. The flow manage are used to manage the movement price of the fluid in the method.

Other Types

Aside from the primary classifications, there are unique hydraulic valves that are utilized dependent on the requirement. Some illustrations would be multi-block directional, modular, cartridge, electro-hydraulic servo, electro-hydraulic proportional/digital, micro-hydraulic and drinking water pressure control.

Multi-block directional types are composed of a primary valve with a number of valves including a directional, a pressure and a check valve that is used to centralize control of the machine. The most secure and most environmental friendly valve on the other hand is the drinking water pressure valve which is utilized to control water in many water hydraulic methods.

4 Ways of Valve Set up Connection

Hydraulic valves are essential to a complete method. That being said, there are four various ways that valves are installed and connected - threaded, modular, sandwich plate and cartridge.

​cartridge valve

Threaded. These valves are generally used for little flow systems as they are light-weight. This valve is very popular and can be mounted along pipelines.

Modular. Modular valves are frequently used with modeling and pressing machines as nicely as with hydraulic power models. The valve makes use of valve sub-plate to link with pipelines.

Sandwich. These valves are versatile as 1 can use it as a single unit or as part of the hydraulic oil link. Frequently, the valve is sandwiched between a direction control and a sub-plate to link with the pipe system.

Cartridge. Cartridges are divided into two different designs - cover plate or a two-way cartridge valve/threaded which can be two or more cartridges. The valves are produced with sleeves, seat, spring, spools and sealing rings. Once all the components are assembled, the valve is then inserted into a valve cavity. The cavity assists shield the components inside making it suitable for hefty machine use.
