Buy Solenoid Valve

The ASCO valve holds a magnetic solenoid tube, which is a cylindrical coil of insulated wires that produce magnetic fields when they are energized correctly. The solenoid valve, like other similar, standard valves, can either be single-threaded, 2-way threaded, 3-way threaded or 4-way threaded, referring to the number of inputs and outputs (entrances and exits) the valves have. The ASCO 3-way solenoid valves or the Control valves have two orifices and three pipe connections. They can be found in three states: normally closed, normally open and universal. ASCO 3-way valves contain many series products, similar to those found in the 2-way series. These include: ASCO General Service for use in air, gas, water and oil services at moderate temperatures, ASCO Steam for use in high pressure and high flow systems, ASCO Air Operated for use in valve shifting with the help of an auxiliary compressed air source. Solenoid valves and the butterfly valves are useful in remote areas, rugged environments, and hazardous locations as they can be operated automatically. For this reason, they are used in a wide range of applications through many industries. Control valves are most commonly used to transfer air and other gases, liquids, hot water and steam, and hydraulic fluids. Application ratings are often applied to these valves to denote specific services for which they may be used. The ratings for solenoid valves are as follows: general service (for working with common fluids), cryogenic fluids (for fluids such as liquid oxygen, liquid argon and liquid nitrogen), vacuum (for working in and maintaining vacuum conditions), and oxygen service (designed to provide contamination-free flow of oxygen).


One of the leading manufacturers of solenoid valves is ASCO Valve, Inc. Solenoid valves get their name from the magnetic tube, known as a solenoid tube, that makes them tick. A solenoid is essentially a tight cylindrical coil of wires that, when energized, produces a magnetic field. This setup allows solenoid valves to be controlled electronically. Like other valves, solenoid valves can have different numbers of inputs and outputs, or entrances and exits. They come in single-threaded, two-way threaded, three-way threaded, and four-way threaded varieties, each of which has its own unique set of uses.

For example, ASCO's three-way solenoid valves, or control valves, have three pipe connections and two orifices. They have three states: normally open, normally closed, and universal. Normally open valves allow fluids to flow under usual conditions, but will start to close under unusual pressure. Inversely, normally closed valves remain closed until unusual pressure starts to build, at which point they will open up. ASCO's three-way valve line, as well as its two-way valve line, has a wide variety of products. ASCO General Service Valves, for example, can be used for water, gas, oil, and air services, so long as they remain at a moderate temperature. ASCO Air Operated Valves are used when an auxiliary compressed air source is to be used in valve shifting. ASCO Steam Valves are used in systems that deal with high pressure or high flow.

Solenoid valves, as well as butterfly valves, can be operated automatically. This makes them extremely useful in dangerous environments, remote areas, and any other situation in which a remotely operated valve is needed. It's largely for this reason that solenoid valves are so widely used throughout many different industries. Because control valves are so common, and can be used for so many different applications, an application rating system was created to denote the specific services for which they can be used. General Service valves handle common fluids that don't put too much stress on the valve. For some of the more dangerous, low-temperature fluids such as liquid oxygen, liquid nitrogen, and liquid argon, a Cryogenic Fluids valve is needed. Vacuum valves are specially designed to regulate and maintain vacuum conditions, a highly demanding task. Finally, Oxygen Service valves are designed to provide a contaminant-free flow of oxygen.

Valves in each of these categories serve a specific and crucial purpose, making ASCO valves an important part of our everyday lives, whether we see them or not.
