Pneumatic three-way asphalt valve SMBX644W-10

Overview of Semir Products

Pneumatic three-way asphalt valve is a rotary valve with a closing element or plunger shape, which can be opened or closed by rotating 90 degrees to make the channel port on the asphalt valve the same or separate from the channel port on the valve body. The shape of the valve plug of the asphalt valve can be cylindrical or conical. In a cylindrical valve plug, the channel is rectangular in shape; In the conical valve plug, the channel is trapezoidal. These shapes make the structure of the asphalt valve lighter, but at the same time, they also result in certain losses. Pneumatic asphalt valves are suitable for cutting off and connecting media as well as diversion applications, but depending on the nature of the application and the erosion resistance of the sealing surface, they can sometimes also be used for throttling A valve with a plug body with a through-hole as the opening and closing component. The plug body rotates with the valve stem to achieve opening and closing actions. Small unfilled plug valves are also known as Cork. The plug body of pneumatic asphalt valves is mostly conical (or cylindrical), which cooperates with the conical hole surface of the valve body to form a sealing pair. Asphalt valve is an early type of valve with a simple structure, quick opening and closing, and low fluid resistance. Ordinary asphalt valves rely on direct contact between precision machined metal plugs and valve bodies for sealing, resulting in poor sealing performance, high opening and closing force, and easy wear. They are usually only suitable for low (not higher than 1 megapascal) and small-diameter (less than 100 millimeters) applications. When installing asphalt valves, in order to prevent damage to the valves and ensure their full performance, the following four points should be noted:

Precautions for installation of Semir products

1. Ensure that the valve is in the open position. Heat the pipeline first. Transfer as much heat as possible from the pipeline to the pneumatic asphalt valve. Avoid prolonging the heating time of the pneumatic asphalt valve itself.

2. Use gauze or wire brush to clean the pipes and cutting areas, making the metal surface shine brightly. It is recommended not to use steel wool.

3. Cut the pipeline vertically first, trim and remove burrs, and measure the pipe diameter. Apply solder flux on the outside of the pipeline and inside the welding cover, and the solder flux must cover the welding surface. Please use solder flux in moderation.
