The most common solenoid valve is the twoway valve. A twoway valve only has two ports, whereas more advanced designs may have three or more, depending on what it will be used for. All solenoid valves, no matter the design, are specified to be one of two general types: either a direct acting valve or a pilot operated valve.
Type. Description. Advantages. Disadvantages. Gate valves. Image Credit: Cameron. Linear motion valves used to start and stop flow. The valve is completely opened when the disk is removed from the flow stream. Classification of gate valves is made by the type of disk used: solid wedge, flexible wedge, split wedge, or parallel disk. No resistance to flow when open

A valve is simply a device that directs or regulates flow by opening, closing or partially obstructing passageways. Valves are instrumental in everything from pumping soap out of a dispenser to starting a jet.
Pilotoperated relief valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency use option would be a rupture disk . Safety valves were first developed for use on steam boilers during the Industrial Revolution .
Also called a dual plate check valve or a folding disc check valve, this type of check valve is good for lowpressure liquid systems as well as gas piping systems. Stop Check Valves. Stop check valves allow you to start and stop the flow in your piping system. They are different .
BASIC VALVE TYPES Valves are available with a wide variety of valve bodies in various styles, materials, connections and sizes. Selection is primarily dependent on the service conditions, the task, and the load characteristics of the application. The most common types are ball valves, butterfly valves, globe valves, and gate valves. Ball Valves:
Likewise, there are other types of these valves that are available today, and that would be the lug style and the wafer style. The most popular would be the wafer style valve. This type would be under the plastic valve. In contrast, lug designed valves contain in them inserts made of metal, which are situated in the valve's bolt holes.
