API 6D Plug Valve

‌RockySea Petro: A Pioneer in API 6D Plug Valve Manufacturing in China

A plug valve is a rotary valve with a closing element or plunger shape, which opens or closes by rotating 90 degrees to connect or separate the channel port on the valve plug from the channel port on the valve body.

RockySea has obtained API Q1, API 6D and ISO standards. RockySea has rich experience in manufacturing plug valves and all products undergo 100% inspection before delivery.

Description

A plug valve is a quick opening and closing through valve. Due to the wiping effect between the rotating sealing surfaces, it can completely prevent contact with the flowing medium when fully open. Therefore, it is usually used for media with suspended particles. 

Another important feature of it is that it is easy to adapt to multi-channel structures, so that a valve can obtain two, three, or even four different flow channels. This can simplify the design of pipeline systems, reduce valve usage, and require some accessories in equipment.

Principle

The shape of the valve plug can be cylindrical or conical. In a cylindrical valve plug, the channel is generally rectangular; In the conical valve plug, the channel is trapezoidal. These shapes make the structure of the plug valve lightweight. It is most suitable as a medium for cutting off and connecting, as well as for diverting, but sometimes it can also be used for throttling depending on the properties of the application and the erosion resistance of the sealing surface.

Type

Divided by structural form, it includes four types: tight set plug valve, self sealing plug valve, plug valve, and oil injection plug valve.

Divided by channel form, it includes three types: straight through plug valve, three-way plug valve, and four-way plug valve.

Divided by purpose, including: soft seal plug valves, oil lubricated hard seal plug valves, and lift type plug valves. 

Advantage

1. Plug valves are used for frequent operation, with quick and lightweight opening and closing.
2. The plug valve has a simple structure, relatively small volume, light weight, and is easy to maintain.3. The plug valve has low fluid resistance.
4. Good sealing performance.
5. No vibration, low noise. 
6. The flow direction of the medium can be arbitrary without being limited by the installation direction.
