1. Long service life with reliable seal and without frequent main tenance
2. Pressure loss
Too much pressure loss will bring increased cost of correlative energy
Butterfly valve have flow characteristics three times better than globe valve,and about 75%
of a same size gate valve
Butterfly valve can be used for on/off service and throttling,They are superior in Multi-function
as compared to gate or globe valves.Butterfly valve can be widely used in chemical field due
to trim options and choice of elastomeric liner.
Butterfly valve have feature of light in weight and small in size,for example, weight and size of
a 10'' butterfly valve are 1/9 and 1/6 of a 10'' gate valve.So butterfly valve is easy to install and
save cost of piping system.
Butterfly valve with resilient seat design can be bubble tight as compared to metal seated gate
or globe valves.
6.Easy of operation
Butterfly valve offer 90-degree open to close.
7. Butterfly valves is approximate 35-40% cost of a same size gate valve. Also low
installed cost than gate valve.
Properly installed butterfly valves are self cleaning and are less susceptible to failure due to
trash material in pipe.
