3 Varieties of Solenoid Valves Explained in Detail Solenoid valves finds application in fluid and air-powered tools, motors, and systems to control the rate of flow. Washing machines and gas boilers makes use of these valves, as well as air hammers and hydraulic pumps because they are equipped with some intrinsic features that are powerful enough to perform both simple and complicated tasks effortlessly. Electric stainless steel solenoid valves and other valve types can be personalized to cater to specific requirements and additionally, be utilized to take charge of a variety of mediums such as air, steam, water and oil. The most commonly used and the most popular solenoid valve has to be the two-way valve. That being said, solenoid valves, irrespective of the design, shape and working mechanism, are specifically one of two general types — a direct-acting valve or pilot operated valve. In this article, we’ll dive deeper into the various types of solenoid valves (namely 3) along with the above mentioned two-way valve, that will help you find the most appropriate one according to your business needs. We’ll start the list with direct acting valve.
In a direct-acting solenoid valve, a coil magnetically opens up the valve in a rapid, direct action. This action lifts the shaft and also the seat of the valve not having anything to do with the outside pressure. These type of electric stainless steel solenoid valves only utilize the full power when opening the valve, as they have the ability to hold their open position even when working on a low-power mode.
For pilot-operated valves, the solenoid triggers a much smaller pilot valve that in in the process opens up a large-sized valve that operates at a much higher pressure ( required in hydraulics or steam), or at a greater volume flow (used for releasing large amount of liquids, gases, or air). Even though piloted valves do not necessarily require much electrical energy to operate, they can be maintained in full power so as to remain in an open-state condition. Furthermore, they can also perform at a slower speed than direct-acting solenoids.
For a two-way valve each of the two ports is alternately used to allow flow and also to close it off. A two-way valve can be configured to be either ‘normally open’ or ‘normally closed’ in its operation. When the valve is opened normally, the valve remains open until some amount of current is applied to stop the valve. Suspension of any kind of electrical power makes the valve to reopen automatically to its default mode. A normally closed one is the most commonly used solenoid valve, which works in the opposite fashion, remaining closed until a power source comes to the rescue.
