Therefore, it is unsuitable for the liquid.
For the impurities in the liquid is easy to block the pilot valve holes. It can be installed randomly (need to be customized), but the requirement for differential pressure condition of the fluid should be satisfied. As for the fluid pressure scope, it has a high upper bound. It can be energized frequently or for a long time, without getting burnt. Instead, the directly operated solenoid valve has no such high requirement.įor the pilot operated solenoid valve, the electromagnetic head is small and the power consumption is low, usually 0.1-0.2W. It has a relatively higher requirement to the purity of the compressed air. In addition, the flow capability of the pilot-operated solenoid valve is bigger than that of the direct acting solenoid valve. So, the pilot pressure is required, otherwise it cannot be opened. As the valve is open, the minimum pressure of the solenoid valve is not allowed to be lower than 0.05MPa.
The pilot-operated solenoid valve is usually used in big diameter and high pressure occasions. Tips: What is a pilot-operated solenoid valve? Purchase Normally Closed 12 volt Solenoid Valve online at low price in India from DNA Technology. (body length unit = mm, port size unit = inch) With high reliability and durability, it is widely used in the industrial fields like chemical, petroleum, pharmaceutical, automotive, light industry, food, mineral processing, electroplating, metallurgy, textiles etc. Pneumatic solenoid valve, 3 way 2 position, normally open, is designed for air control with power supplied by 12V DC, 24V DC, 110V AC, or 220V AC. 12V DC 1/2 Electric Solenoid Water Air Valve Switch (Normally Closed) Controls the flow of fluid+air and act as a valve between high-pressure water or any.
