Butterfly has a simple structure, small size, light weight, material consumption province, small installation size, switch quickly, 90 ° reciprocating rotary valve Tianjin Tanggu, driving torque characteristics of small, used to cut, turn, adjust the line of medium Wuxi Tanggu valve, having a good fluid seal off control characteristics and performance. Butterfly can carry mud accumulation of fluid in the pipe mouth least. Under low pressure, can achieve a good seal. Regulation performance. The streamlined design of the disc, so that the loss of fluid resistance small Chengdu Tanggu Valve, can be described as an energy-saving products. Suitable for flow adjustment valve. Butterfly pressure loss due to the relatively large tube, which is about three times the Tanggu gate valves, butterfly valves in the choice should fully consider the impact of the pipeline system by the pressure loss should be considered closed when the disc withstand medium pressure pipeline strength. You must also consider limiting the operating temperature at high temperatures endured elastic seat material. Typically, throttle control and regulate mud medium, requires shorter length of the structure, opening and closing speed, low-voltage cut-off (pressure difference), recommended use butterfly. In the double-digit adjusted necking channel, low noise, cavitation and vaporization, a small amount of leakage to the atmosphere, when the abrasive media has, the choice of butterfly. Throttle, or require sealing strict, severe abrasion, low temperature (cryogenic) under working conditions, such as in special working conditions. Wuxi Ming Tanggu Valve _ _ Tanggu Port Valve Valve Valve is provided by the Hong Kong Science and Technology Co., Ltd., Dongguan Ming. Port Valve Co., Ltd., Dongguan Ming (www.gdmgfm.com) is Dongguan, butterfly leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the next port of the valve leading the staff warmly welcome all inquiries negotiations to create the next port of the valve a better future.
