Butterfly valves are commonly used in piping systems to control and regulate flow and speed.
The use of butterfly valve is also relatively simple, easy to operate. And butterfly valve is widely used in all walks of life, is an important control fluid system equipment.
, for air conditioning system: A butterfly valve can control the flow of air conditioning pump and piping system to adjust the temperature of the air conditioning system, so that the air conditioning system can work more efficiently.
2, for water treatment: butterfly valve can be used for water treatment process, can effectively control and adjust the flow of water pipe, carefully adjust the appropriate quality of water.
3, used for power system: butterfly valve can also be used for power system, can effectively control and adjust the flow of water and pressure in the power system, to ensure the normal operation of the power system.
4, used for heating system: butterfly valve can also be used for heating system, can control the flow of hot water piping system and adjust the temperature of the heating system, in order to meet the temperature requirements of the house.
In general, the use of butterfly valves is very wide, from air conditioning systems to water treatment, from power systems to heating systems, a variety of industries can benefit from the use of butterfly valves. Moreover, butterfly valve structure is simple, easy to maintain, for enterprises is also an affordable choice.
