Product Description
Butterfly valve is opened and closed by disc type Reciprocating gyrati Open close and adjust at about 90 degrees A valve for regulating fluid passages.
Butterfly valves are not only simple in structure, small in volume, light in weight, low in material consumption, small in installation size, small in driving moment, simple in operation and fast in operation, but also have good flow regulation function and sealing characteristics.
They are one of the fastest growing valve varieties in recent decades. Especially in developed countries such as America, Japan, Germany, France and Italy, butterfly valves are widely used. The varieties and quantities of butterfly valves are still expanding, and they are developing toward high temperature, high pressure, large caliber, high sealing, long life, excellent regulation characteristics and multi-function of valves.
Their reliability and other performance indexes are all equal. Up to a higher level, and has partially replaced globe valves, gate valves and ball valves. With the advancement of butterfly valve technology, butterfly valve will become the dominant valve form in a predictable short time, especially in the field of large and medium caliber, medium and low pressure.
In order to meet the requirements of industrial applications such as high and low temperature, strong erosion and long service
Butterfly valves are easy and fast to open.
Butterfly valves are relatively inexpensive to build.
Butterfly valves have less space requirements.
Butterfly Valves are generally associated with reduced maintenance.
