Parameter:
The aluminum alloy butterfly valve is made of high-performance material, which can effectively prevent the temperature difference of the valve body, isolate the transfer of medium in the pipeline and not condense on the surface of the actuator and flange. The high performance material has many outstanding advantages: such as low water absorption, corrosion resistance, heat insulation, cold resistance, etc., which is four times more than ordinary materials. Anti-condensation butterfly valve is suitable for HVAC, central air conditioning, and water supply equipment, widely used in water, gas, petroleum, chemical, smelting, energy, shipbuilding, electric power, oil, water treatment, construction, and other industries.
Anti-condensation butterfly valves are generally made of aluminum alloy body and light weight driving device. The aluminum alloy valve body has strong corrosion resistance and is light in weight, making it easy to install; the butterfly plate is surrounded by a spherical structure, which is conducive to reducing the friction torque with the valve seat; the butterfly plate and valve shaft are made of stainless steel, which increases the ability to prevent rust and corrosion and at the same time plays a role in reducing heat transfer and preventing the temperature of the drive unit from being too low; the housing of the drive unit is made of aluminum alloy, which is light in weight and dissipates heat quickly, which is conducive to the distribution of moisture; the vulcanized rubber valve seat and The use of vulcanized rubber seats and long steel necks further reduce heat transfer.

Advantages of aluminum butterfly valve:
1. High sealing performance
Wide disc seating contact for high sealing performance;
Stem seal bearings are assembled on the top and bottom stems for stable sealing
Reinforced ribbing minimizes valve operating problems such as distortion, skidding, and exfoliation of rubber liners caused by line pressure load and friction with metal discs;
2. Aluminum die-cast valve body to prevent corrosion
Light aluminum alloy valve body, small torque, easy to use and install;
3. Longer valve seat service life
Some multi-level progressive contact valve seat design allows the valve plate to gradually contact the valve seat during the closing process, which reduces unnecessary torque while ensuring good sealing performance, thereby prolonging the service life of the valve seat;
4. Good anti-corrosion and sealing performance
Some valve stem sealing rings prevent fluid leakage;Valve seats of different materials adapt to different working conditions and have good anti-corrosion and sealing performance;
5. Multi-stage progressive contact valve seat design
The unique multi-level progressive contact seat design of the anti-condensation butterfly valve makes the valve plate gradually contact the seat during the closing process.
6. Valve body is made of light aluminum alloy body
The valve body is made of light aluminum alloy body, with low torque, preventing rust, and preventing long-term circulation of chilled water in the air conditioner.
7. Stronger anti-condensation function
The low temperature of the fluid in the pipeline follows the conduction of the butterfly valve metal material and exchanges with the ambient air temperature to produce condensation.
8. The valve plate is processed as a complete spherical shape
Each part of the sealing surface is a part of the spherical surface, even the axial sealing surface at the upper and lower parts of the valve plate.
