The industrial plants require plug valves for effective flow control in applications that range from the oil and gas industry to water treatment processes. The design simplicity makes it possible for them to operate effectively even under tough conditions.
What is a Plug Valve?
A plug valve consists of a cylindrical/tapered body, which has a hole or channel running from end to end of the cylinder. If the channel is in alignment with the pipe, the flow is permitted. Turning the valve by 90° restricts the path for flow of fluids.
The simplicity in design helps in reducing the number of movable parts, thereby ensuring reliable operation.
Types of Plug Valves
Lubricated Plug Valve
Lubricated plug valves utilize a sealing lubricant injected between the plug and body surfaces. This lubricant reduces friction and assists with sealing during operation.
Non-Lubricated Plug Valve
Non-lubricated plug valves use sleeves or liners instead of lubrication systems. These valves require less maintenance and are commonly used in general industrial services.
Eccentric Plug Valve
Eccentric plug valves feature an offset plug design that minimizes contact between sealing surfaces during operation. They are often selected for wastewater and slurry applications.
Multi Port Plug Valve
Multi port plug valves contain multiple flow passages within a single valve body. These valves simplify piping layouts and provide flow diversion capabilities.
Jacketed Plug Valve
Jacketed plug valves are designed with external jackets that allow heating or cooling media to circulate around the valve body. These valves are suitable for temperature-sensitive fluids.
