What is a gate valve?

A gate valve is a control valve that either allows media to flow through unobstructed or stops the fluid flow. The main advantage of a gate valve is the straight-through unobstructed passageway, which induces minimal pressure loss over the valve. The unobstructed bore of valve also allows for a pig’s passage in cleaning pipe procedures, unlike butterfly valves. However, gate valves are slower than quarter-turn valves and should only be used in the fully open or closed position, not to regulate the flow. Automated gate valves exist with either an electric or pneumatic actuator, but manual gate valves are cost-effective since gate valves are typically used infrequently. Gate valves are also commonly referred to as sluice gate valves.

Applications of Gate Valve

Gate valves have numerous industrial and residential applications. •Slurries: Gate valves are often used in applications that contain slurries as their media. This is because a gate valve has an unobstructed passageway for the fluid, so the slurry can easily pass through the valve. In addition, knife gate valves can easily cut right through the slurry to close •Viscous media: Gate valves are commonly used for viscous media like light grease and oils. The unobstructed passageway allows these medias to flow easily. The valve can be pigged, a common cleaning method for these applications. In addition, valves for these applications are typically on or off for long periods of time. •Water gate valves: For water applications, water gate valves are commonly used since flow control is typically not done for these applications. The valve can be fully open or fully closed, allowing for proper water control. Check out our range of non-IBR valves here!
