1.Aegulator before and after the pressure is small, requires a small amount of leakage, the general choice of single-seat valve.
    2.When adjustabled low pressure, high flow gas can be used butterfly valve.
    3.Adjustment of highly corrosive media, the choice of diaphragm valve, single seat valve 4.Not only require adjustment, but also requires        cutting, the choice of eccentric rotary valve. There are other features of this ball valve, butterfly valve, diaphragm valve.
    5.The larger the noise, the choice of sleeve valve.
    6.Control high viscosity, with fiber, fine particle media can choose eccentric rotary valve or V-type ball valve.
    7.It particularly applicable to the slurry material regulating valve with ball valve, diaphragm valves, butterfly valves and so on
