Working of a Pilot Valve in the Hydraulic System

A hydraulic system uses hydraulic fluid, which is pushed by different valves and tubes for the functioning of machinery. These valves direct the flow of a fluid through the hydraulic system. It is essential to choose the appropriate type of valve to serve the intended purpose of the application.

Hydraulic valves are available in different sizes depending upon the rate of flow and pressure in the hydraulic system. A hydraulic pilot valve is responsible to control the high pressure of the hydraulic fluid and regulate the operation of the other valves. You can get any type of hydraulic valve from the service provider having expertise in hydraulic component industry providing varied valves and other hydraulic solutions. Internet is a great platform to jot down the details of the companies offering quality and durable hydraulic products at cost-effective prices.

Generally, the valves in hydraulic equipment are known as pilot operated valves as they can be pressure regulator, solenoid or check valves. A pilot valve works as an open and close switch allowing the hydraulic fluid to transmit into the other valves. Once the liquid goes to the other valves, each valve performs the next part of the hydraulic process to ensure proper working. This type of valve has usually 2 or 3 port valves and a sliding or poppet design. A sliding or spool design uses a spring and metal shaft whereas a poppet design has a disc with an opening that gets open when the pressure is build up on the shaft and pushes the springs. Poppet designed pilot valves can be called as direct acting valves as no pressure is required to open the valve whereas spool or sliding valves are indirect acting valves that require a certain amount of pressure before the spool moves.

A hydraulic pilot valve has a predefined pressure setting indicating when the valve has to open and close. The pressure sensor determines the pressure around the pilot valve and gets open to release hydraulic fluid into the other valves until the pressure setting gets down. The working of the secondary valves are entirely dependent on the pilot valve. Hence, if there is any malfunction in the hydraulic pilot valve, then it will affect the complete hydraulic system and make it unusable. Regular inspection of this type of valve ensures negligible internal leakage and long service life. You can repair the valve or call an expert for the assistance. If there are minor damages, then just disassemble the parts to clean them properly. There are several features of pilot valve, which makes it unique including:

- It has small dimensions allowing uncomplicated and compact installation.
- It is robust and long-lasting, thereby, offering greater reliability and easy servicing.
- It has low hysteresis allowing consistent machine function response to valve actuation.
- Pilot valves offer application optimization and better flexibility in system design.

Hence, these are the features of a hydraulic pilot valve. For more information, choose the right source like internet. Start surfing the web to get the profound details about pilot valves.
