Worm wheel butterfly valve which material is good

Worm wheel butterfly valve which material is good

Worm wheel butterfly valve is installed in the body of the butterfly valve worm gear, by turning the handwheel on the head of the worm wheel to achieve the opening and closing of the butterfly valve, the advantage of the worm wheel drive is very labor-saving, the larger the caliber of the butterfly valve, the more the advantages of the worm wheel drive can be reflected. Common worm gear butterfly valve materials are gray cast iron, ductile cast iron, stainless steel, cast steel, aluminum alloy and so on. So worm wheel butterfly valve these kinds of materials, which one is good?

Worm wheel butterfly valve using different materials, can adapt to different working conditions. So if you want to say which material is good, it is stainless steel, stainless steel material turbine butterfly valve adaptability is stronger, but the cost is also the highest. In some common working conditions, the use of stainless steel worm gear butterfly valve will increase the cost.

Generally speaking, in the water, steam, oil, such as room temperature, low pressure media, the use of gray cast iron, ductile iron material turbine butterfly valve is most suitable.

If the over medium is high temperature and high pressure, such as steam, high temperature liquid, etc., it is suitable to use cast steel material worm gear butterfly valve.

And stainless steel material worm wheel butterfly valve, in the corrosive liquid medium used in the best, such as hospital wastewater, chemical plants and so on. Also because stainless steel worm gear butterfly valve used in the food industry.

And the worm gear butterfly valve made of aluminum alloy can only be used in the air conditioning water system because of its anti-condensation function. And with the continuous optimization of ductile iron butterfly valve, it has begun to replace the aluminum alloy butterfly valve in the air conditioning water system.
