All You Want to Know About Hydraulic Control Valves
Hydraulic Control System 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. If hydraulic nozzlea are not used, then most of the processes would have become ineffective and unsafe. The hydraulic valves have been in existence for many long years but we started using it only lately. In the early days these nozzle were only used in the science labs for conducting various experiments but now hydraulic valves are used for a variety of purposes. There have been many innovations on this product which is the reason why they are found important for several applications.
The purpose for which a hydraulic nozzle is used depends on its shape. One such kind of hydraulic valves are control valves which are used to modify and transfer the pressure and flow of hydraulic fluid in the hydraulic systems. The hydraulic control nozzle comes in different sizes and pressure ratings. The different types of Hydraulic control valves are classified by a relationship between the nozzle stem-position and flow rate through the nozzle. The hydraulic control nozzles consist of a main valve and attachments such as pilot valve, pipeline, ball nozzle, needle valve and manometer. You can find different designs of control valves including check, relief, cartridge, shut off, safety, and solenoid valves.
While in an open position, these valves permit the flow of fluid and they prevent the flow when the valve is in a closed position. The hydraulic valves are mostly used to prevent the improper levels of pressure in Hydraulic Control System. There are some nozzles which stop the flow when the rates get too high, while there are valves which transmit signals to other valves in order to maintain the systematic balance of flow.
