What influences the butterfly valve price?-Belo Valve

The butterfly valve has a simple and compact structure and is easy and convenient to install and maintain, so even if there are many various kinds of industrial valves products, butterfly valve is still one of the most widely used valves products. Butterfly valves are in great demand in the market, one reason is due to the unique characteristics of butterfly valve. Butterfly valves can be not only used as shut-off valves, also can be used as regulating valves to regulate the medium flow rate; the other reason is that there are various different types of butterfly valves, which can meet the requirements of different mediums and different working conditions( different pressure and different temperature). so with different requirements, different butterfly valves are used, and also the price for various butterfly valves are different; in order to check whether we are buy the butterfly valves with reasonable prices, we should know first which items will influence the butterfly valve price; 

1. the different end connects will influence the butterfly valve price: 

There are three most common end connections: flange end connect butterfly valve, wafer end connect butterfly valve( wafer lug end connect butterfly valve), and welded end connect butterfly valve, when the parameters,size and diameter are the same, the price of flange end connect butterfly valve will be higher than that of wafer type end connect butterfly valve, the price of welded end connect butterfly valve will be higher than that of the flange end connect butterfly valve; 

2. The different driving forms will influence the price of butterfly valves:

there are commonly four types of driving forms manual lever butterfly valve, worm gear actuated butterfly valves, electric actuated butterfly valve, pneumatic actuated butterfly valves; according to the cost calculation, the price of the manual lever handle butterfly valve is the lowest, the price of worm gear actuated butterfly valve is a little higher than that of the manual lever handle butterfly valve, but the price of worm gear operated butterfly valve will not be as expensive as the electric actuated and pneumatic actuated butterfly valves. The price of electric actuated and pneumatic actuated butterfly valves is relatively the highest; 

3. The different body material for butterfly valve will influence the price of butterfly valves:

the commonly used materials for body of butterfly valves are gray cast iron, ductile cast iron, carbon steel, stainless steel, bronze,etc. Butterfly valves made of gray cast iron are the most traditional and relatively cheap. In general, the price of gray cast iron butterfly valve is cheaper than that of ductile iron butterfly valve, the price of ductile iron butterfly valve is cheaper than that of carbon steel butterfly valve, and the price of carbon steel butterfly valve is cheaper than that of stainless steel butterfly valve( including stainless steel 304 butterfly valve, stainless steel 316 butterfly valve, stainless steel 316L butterfly valve); 

4. The different sealing material used will also influence the prices of butterfly valves: 

The sealing surface of the butterfly valve can be made into resilient soft seal or metal hard seal. The manufacturing cost of the metal hard seal butterfly valve is usually higher than that of the resilient soft seal butterfly valve, so the price of hard seal butterfly valve is also higher than that of the soft seal butterfly valve. Usually concentric butterfly valves are using resilient soft sealing materials, and eccentric butterfly valves are using metal hard sealing materials, so most of the time, the price of eccentric butterfly valve is higher than that of the concentric butterfly valve. 

Of course , in addition to the above factors, the price of butterfly valve is also affected by other butterfly valve accessories( like valve shaft, valve disc), and the working temperature and pressure of the pipelines. And each factor does not stand alone. For a complete butterfly valve, its price is affected by many factors. So if the buyer want to get a specific proper price for the butterfly valve you are looking for, please offer the manufacturer the detailed requirements and parameters of the butterfly valves, so which can guarantee you can purchase the proper butterfly valves with reasonable prices.
