The high temperature butterfly valve is a new generation of high temperature butterfly valve developed by introducing foreign advanced technology and combining with domestic manufacturing technology. High temperature butterfly valve is widely used in high temperature gas pipeline in metallurgy, building materials, chemical industry, power plant, glass and other industries. As a high temperature gas medium flow regulating or cutting device, high temperature butterfly valve can be used with various actuators to form different performance equipment.

At present, the high temperature butterfly valve is used as a kind of components used to realize the pipe breaking and flow control. With its own characteristics and advantages, the butterfly valve has been widely used in many fields, such as oil, chemical, metallurgy, hydropower and so on. Let's learn about the characteristics and advantages of high temperature butterfly valves.

Characteristics of high temperature butterfly valve:

1, the high temperature butterfly valve has the characteristics of simple structure, small size, light weight, material consumption, small installation size, fast switch, 90 degree reciprocating and rotary, small driving torque, etc., for cutting, connecting and adjusting the medium in the pipeline. It has good fluid control characteristics and close sealing performance.

2. Mud can be transported and liquid stored at the pipe mouth minimum. A good seal can be achieved under low pressure. The regulation performance is good.

3. The streamline design of the high temperature butterfly plate makes the fluid resistance loss small, so it can be regarded as an energy saving product.

4, the stem is a bar structure, after quenching and tempering treatment, has good comprehensive mechanical properties and corrosion resistance, scratch resistance.  When the butterfly valve is opened and closed, the stem only rotates without lifting and running. The packing of the stem is not easy to damage, and the sealing is reliable. It is fixed with the butterfly plate cone pin, and the overhanging end is designed to prevent the blow out, so that the stem will collapse when the valve stem and butterfly plate joint break accidentally.
5, the connection way is flange connection, clip pair connection, butt welding connection and lug clip connection. The driving form is manual, worm wheel drive, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.

Advantages of high temperature butterfly valve:

1. opening and closing is convenient, fast, labor-saving, low fluid resistance, and can be operated regularly.

2. it is simple in structure, small in size, short in structure, small in size and light in weight. It is suitable for large caliber valves.

3. mud can be transported and liquid stored at the pipe mouth minimum.

4. low pressure, good seal can be achieved

5. good regulation performance

6. when the valve is opened, the effective flow area of the valve seat is larger, and the fluid resistance is smaller.

7. the opening and closing torque is small, because the butterfly plates on both sides of the rotating shaft are basically equal in the medium action, and the torque direction is opposite, so opening and closing is called labor saving.

8. sealing surface materials generally use rubber, plastic, so low pressure sealing performance is good.

9. easy to install

10. the operation is flexible and labor-saving. Manual, electric, pneumatic and hydraulic methods can be selected.
