4 inch victaulic butterfly valve
China 4 inch victaulic butterfly valve manufacturer recommends that in throttling, regulating control, and mud media, the structural length should be short and the opening and closing speed should be fast (1/4 turn). Low pressure cutoff (low pressure difference), butterfly valve is recommended.
Butterfly valves can be used for dual position regulation, necked channels, low noise, cavitation and gasification phenomena, small leakage into the atmosphere, and abrasive media.
When using butterfly valves under special operating conditions such as throttling adjustment, strict sealing requirements, severe wear, low temperature (deep cold), etc., special designed metal sealing belt adjustment devices with three or two eccentric special butterfly valves are required.
