COMMON VALVE TYPES AND THEIR APPLICATIONS
Valves feature a range of characteristics, standards, and groupings the help to give you an idea of their intended applications and expected performance. Valve designs are one of the most basic ways to sort the huge range of valves available and finding a good fit for a project or process.
Ball Valve
Predominantly equipped with quick-acting 90-degree turn handles, these valves use a ball to control flow to provide easy on-off control. Generally accepted by operators to be faster and easier to operate than gate valves.
Butterfly Valve
Using a compact design, the butterfly valve is a quick-acting rotary motion valve ideal for tight spaces thanks to its wafer type design. Butterfly valve bodies are offered in many different configurations.
Check Valve
Used to prevent backflow, these valves are typically self-activated allowing the valve automatically opens when media passes through the valve in the intended direction and close should flow reverse.
Gate Valve
As one of the most common valve types, gate valves use linear motion to start and stop the flow. These are typically not used for flow regulation. Instead, they used in the fully open or closed positions.
Needle Valve
Typically used in small diameter piping systems when fine, accurate flow control is needed, Needle valves get their name from the point on a conical disc used within.
Knife Gate Valve
Typically used for controlling flow of media containing solids, the knife gate valve features a thin gate controlled through linear action which can cut through materials and create a seal.
While not suited for high-pressure implementations, these valves are ideal for use with grease, oils, paper pulp, slurry, wastewater and other media which might obstruct the operation of other valve types.
Plug Valve
Using a quick-acting quarter-turn valve handle, these valves control flow using tapered or cylindrical plugs. They provide some of the best ratings when tight shutoff is essential and are reliable in high-pressure or high-temperature environments.
Pressure Relief Valve
Used to help improve safety, these valves are spring-automated and will help to return a system to the desired pressure during over-pressure events.
