In several common connection ways of butterfly valves, the price of wafer type is the cheapest, followed by lug type butterfly valve, flange type butterfly valve is the most expensive, the price is proportional to the overall weight. In the relevant standard, it is not clear whether the pressure hole of the lug type is a through hole or a threaded hole, so both on the market can be seen.
Application:
1. These products are mainly used for pipeline flow, pressure and temperature control of various industrial automation productiong, for example: Electricity, petrifaction, metallurgy, environmental protection, energy management, fir-fighting systems.
2. Simultaneously they have good fluid control properties, and can operate simply.
3. They are not only widely used in general industries as petroleum, coal gas, chemical engineering, water treatment, but also used in the cooling water system of thermal power plant.
