three-way brass plug valve
I. Product Overview:
The X16W three-way brass plug valve is a rotary valve with a closing element or plug. By rotating 90 degrees, the port on the plug aligns with or separates from the port on the valve body, enabling the valve to open or close. The plug of a plug valve can be cylindrical or conical. In a cylindrical plug, the passage is generally rectangular; while in a conical plug, the passage is trapezoidal. These shapes make the plug valve structure lightweight, but they also result in certain losses. Plug valves are most suitable for cutting off and connecting media as well as for diverting, but depending on the nature of the application and the erosion resistance of the sealing surface, they can sometimes be used for throttling. Since the movement between the sealing surfaces of a plug valve has a wiping effect, and it can completely prevent contact with the flowing medium when fully open, it is usually also suitable for media containing suspended particles. Another important feature of plug valves is that they are easily adaptable to multi-channel structures, so a single valve can have two, three, or even four different flow passages. This can simplify the design of the piping system, reduce the number of valves, and eliminate some connecting fittings required in equipment.
II. Product Features:
(1) Suitable for frequent operation, with quick opening and closing and light operation.
(2) Low fluid resistance.
(3) Simple structure, relatively small volume, light weight, and easy to maintain.
(4) Good sealing performance.
(5) Not restricted by installation direction, the medium flow direction can be arbitrary.
(6) No vibration, low noise.
