- Standard: GBT12238The fluid resistance is small, and the ball valve is the one with the smallest fluid resistance among all valves. Even if it is a reduced diameter ball valve, its fluid resistance is quite small.
The thrust bearing reduces the frictional moment of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.
The sealing performance of the valve seat is good, and the sealing ring made of ammunition materials such as polytetrafluoroethylene is adopted, and the structure is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of the medium pressure.
4. The sealing of the valve stem is reliable. Since the valve stem only performs imitation rotation and does not perform lifting movement, the packing seal of the valve stem is not easy to be damaged, and the sealing ability increases with the pressure of the medium.
5. Due to the good self-lubricating properties of polytetrafluoroethylene and other materials, the friction loss with the ball is small, so the service life of the ball valve is long.
6. Bottom-mounted valve stem and the convex step on the head of the valve stem prevent the valve stem from blowing out. If the valve stem seal is damaged due to fire, metal contact can also be formed between the convex step and the valve body to ensure the sealing of the valve stem.
7. Anti-static function: a spring is set between the ball, the valve stem and the valve body, which can discharge the static electricity generated during the switching process
-
- During the use of the valve, the medium flows in the direction of the arrow in the diagram.
- When the medium flows in the specified direction, the valve flap is opened by the force of the medium;
- When the medium flows backwards, due to the self-weight of the valve disc and the action of the reverse force of the medium on the valve disc, the valve disc and the sealing surface of the valve seat are tightly closed to prevent the reverse flow of the medium.
- The sealing surface of the valve body and disc is made of stainless steel surfacing
-

Flanged Hard Seal Butterfly Valve Overview
- The nominal pressure range of THM343H-10/16/25/40C flange hard seal eccentric butterfly valve is PN10~PN40.
- The multi-layer metal hard seal butterfly valve adopts a precise J-shaped elastic sealing ring and a three-eccentric multi-layer metal hard seal structure.
- Widely used in metallurgy, electric power, petrochemical, water supply and drainage, and municipal construction industrial pipelines where the medium temperature is ≤ 425°C, for regulating flow and carrying and breaking fluid.
- Flange Hard Seal Butterfly Valve THM343H-10 Features
- 1. The metal hard seal butterfly valve adopts a triple eccentric sealing structure, the valve seat and the butterfly plate are almost free of wear, and have a tighter and tighter sealing function.
- 2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance, corrosion resistance and long service life no matter in the case of low temperature or high temperature.
- 3. The sealing surface of the butterfly plate is made of surfacing welding cobalt-based hard alloy, which is wear-resistant and has a long service life.
- 4. The large-size butterfly plate adopts quilted frame structure, which has high strength, large flow area and small flow resistance.
- 5. The metal hard seal butterfly valve has a two-way sealing function. It is not restricted by the flow direction of the medium or affected by the space position during installation, and can be installed in any direction.
- 6. The driving device can be installed in multiple positions (rotating 90° or 180°), which is convenient for users to use.
- Flange hard seal butterfly valve D343H-10 application scope:
- It has been widely used in petrochemical, power plants, steel mills, metallurgy, petroleum, food, chemical, beverage, medicine, industrial environmental protection water treatment, high-rise building water supply and drainage pipelines, etc. to adjust medium flow and open and close. use.
