Plug Valves

Daume Valve Division offer a range of plug valves to suit a broad a variety of applications, reliably addressing the vast majority of requirements.

Plug valves offer one of the most economical control options for manufacturing lines; the correct valve can deliver improved production time and reduced risk of failure. You can find more information on their application, functionality as well as supporting documentation below.

Plug Valves: Purpose & Functionality

A Plug Valve is a flow control device designed to regulate the flow of a liquid or gas within a high-pressure system. As well as controlling flow via basic moderate throttling, plug valves can be used in on/off position or to divert flow or combine flow.

Plug valves are a mechanically simple valve that utilises cylindrical or conically tapered "plugs" which rotate inside the valve body to control flow through the valve. The plugs within the valve contain one or more hollow channel that cuts sideways through the plug, this allows fluid or gas to flow through the plug when the valve is open. This simple mechanism and ease of operation mean that plug valves are often economical.

Applications

Plug valves are effective tight shut-off and on valves, suitable for use systems as well as with corrosive & hazardous liquids and gas. They are often used in the following applications:

Chemical service
Corrosive substances
Vacuum to high-pressure
Oil piping systems
Extreme temperature flow applications (-196°C to +800°C)
High-pressure flow applications

Different Types of Plug Valves

Two-Port Valves

A two-port valve features two ports allowing fluid to enter or leave, it has two positions, open to allow flow and closed to stop the flow. A two-port valve has one passageway, for flow to pass through it.

The ports are usually at parallel ends of the valve body; therefore, the plug is rotated a fourth of a full turn to change from open to shut positions.
