Basic knowledge about Throttle Valve

Under high temperature conditions, the Valve Stem does not come into contact with the medium, ensuring zero leakage from the valve stem. At the same time, it ensures sufficient strength and toughness and can be opened and closed tens of thousands of times. Longer service life and easy and convenient operation. The opening and closing part of the steam Throttle Valve is a plug-shaped Universal Valve. The sealing surface is flat or conical. The Universal Valve moves linearly along the center line of the fluid. It is also called a cut-off valve. It is a frequently used valve. Due to its opening and closing During the process, the friction between the sealing surfaces is small, relatively durable, the opening height is not large, easy to manufacture, and convenient to maintain. It is not only suitable for medium and low pressure, but also for high pressure.

As a pressure pipeline component, valves control the connection and cutoff of pipeline fluids. They are like brake pads on a car. Once damaged, the consequences will be disastrous. Therefore, the performance and service life of the valve directly affect the normal operation of the pipeline system. Once the valve is damaged, the system must be shut down for maintenance, and the loss incurred is not the cost of several valves.
The Throttle Valve is particularly outstanding in these two aspects. It has double seals to ensure zero leakage, and it meets the zero leakage standard of helium mass spectrometry detection, making it very safe and reliable. The number of cycles of the bellows can reach more than 10,000 cycles without damage, which is several times longer than the switching life of the ordinary Throttle Valve packing seal. In addition, the bellows valve can prevent external dust from entering the valve body and ensure the cleanliness of the medium. For example, under working conditions such as high-purity silicon powder, pure oxygen, food, and vacuum, the performance of the Throttle Valve is very outstanding.
1. The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance;
2. The sealing surface is overlayed with Co-based carbide, which is wear-resistant, corrosion-resistant, anti-friction and has a long service life;
3. The valve stem is quenched and tempered and its surface is nitrided, which has good anti-corrosion and anti-friction properties;
4. Double sealing, more reliable performance and zero leakage;
5. Valve stem lifting position indication is more intuitive;
6. Part materials, flange and butt weld number sizes can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
