Hydraulic valves, (or nozzles) do have great importance in our daily life. The hydraulic valves are used for controlling the pressure and flow rate of fluids in a hydraulic system.
Hydraulic valves are very important because they help control the flow of special fluids, oils, in the system. Choosing the most suitable valve (s) is very important for any hydraulic system. Distributors of Valves Expansion comes in various sizes and types depending on the system pressure and flow rate.
There are three main classifications of hydraulic – directional, pressure and flow control. Directional used to control the direction of fluid from beginning to end. However, the pressure valve is used when a certain pressure level is required. Flow control is used to control the flow rate of fluid in the system.
The other type
Aside from the major classification, there are special hydraulic valves used depending on the needs. Some examples would be multi-directional block, modular, cartridge, servo electro-hydraulic, electro-hydraulic proportional / digital, micro-hydraulic and water pressure control.
Multi-directional block consists of a main valve with a valve including directional, pressure and valves used for centralized control of the machine. The safest and most environmentally friendly valve on the other hand is a water pressure valve is used to control the water in many water hydraulic system.
4 Ways Valve Installation Connection
A hydraulic valve is essential for a complete system. That being said, there are four different ways that the valve is installed and connected – threaded, modular, plate of bread and cartridge.
Threaded. These valves are typically used for small flow systems because of their light weight. These valves are very popular and can be installed along the pipeline.
Modular. A modular valve is often used with modeling and pressing machines as well as with a hydraulic power unit.
Sandwich. These valves are flexible as one can use it as a single unit or as part of hydraulic oil connections. Often, the valve is sandwiched between the control direction and the sub-plate to be connected to the pipeline system.
Bullet. Cartridges are divided into two different styles – the cover plate or two-way cartridge valve / screw that can be two or more cartridges. The valves are made with arms, seat, spring, rolls and sealing rings.
