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 Intake Valve
BIV’s are the ideal alternative to master intake valves integrated into the apparatus pump system because they eliminate the need for apparatus to be taken out of service for repair or maintenance of an intake valve. Units are constructed of lightweight, hard anodized and powder coated aluminum alloy. In addition, hose couplings and truck connections are attached to the valve using polymer bearing rings which provide electrical isolation to help prevent galvanic corrosion.
Ball Valve/Swing out Valves
Predominantly equipped with quickacting 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.
Hydrant Valve
A hydrant valve is a lightweight valve with a full, unobstructed 2.5” waterway, A full-flow hydrant valve is the connection point where firefighters can tap into a water source.
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.
Pinch Valve
Often used for handling solid materials, slurries and liquids with suspended solids, pinch valves use a linear motion. Typically, Pinch Valves feature an internal sleeve to isolate the media.
Globe Valve
Globe valves are typically applied in modulating control operations. Typically, available in three body types, T-body (as shown above), Y-Pattern, and Angle body.
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.
