Q: Role of ball valve DN20-Q11F-16: Q11F ball valve is to control the circulation and cut-off of the pipeline medium.

Q: The difference between ball valve Q341F and Q347F: Ball valves Q341F and Q347F are turbine driven soft sealing flange ball valve, Q341F is a fixed ball valve, Q347F is a floating ball valve

Q: What domestic PPR ball valve can withstand acid and alkali?: Yue Yue PPR ball valve products are made of pure raw materials, mainly used in water supply and other plastic piping systems for industrial use. You can rest assured that the use of Hong Yue products

Q: What's the difference between a ball valve and a butterfly valve? Which one has better sealing performance?: (1) the butterfly valve from the valve body, valve seat, valve plate, valve rod, all parts are a significant drain on the outside, one eye can see; the ball valve is composed of a valve body, the valve core (a round ball), valve rod, valve position is in the valve body inside, the naked eye can see only a part, so the seal the performance of the valve than the butterfly valve well;

Q: What is the difference between ball valve and butterfly valve?: The butterfly valve consists of valve body, valve seat, valve plate, valve rod, all parts are a significant drain on the outside, one eye can see; and the ball valve is composed of a valve body, the valve core (a round ball), valve rod, valve position is in the valve body inside, the naked eye can see only a part, so the sealing performance of the ball valve than the butterfly valve; butterfly valve structure is relatively simple, generally with low pressure valve, high pressure valve can reach 64 kg. The ball valve structure is relatively complex, more resistant to high pressure, the ball valve up to 100 kg.Butterfly valves are divided into soft seal and seal, soft seal butterfly valve is generally perpendicular to the center of the plate, is the valve plate, valve seat, valve stem is the center position of the highest temperature soft sealing butterfly valve is 150 degrees below the pressure of 16 kg, hard seal butterfly valve can be divided into single eccentric, double eccentric, three eccentric, we generally use more than three eccentric, because the three eccentric according to its structure, better sealing performance, hard seal butterfly valve pressure is 64 kg; the valve can also be divided into soft seal and seal, soft seal valve maximum temperature is below 280 degrees, the pressure is on 64 kg, hard seal ball valve temperature can reach 425 degrees below the pressure below 100 kilograms. Shanghai Sino US valve for your answer, for reference.

Q: Valve and ball valve is the same thing? Don't know don't speak: Ball valves belong to a large class of valves, valves include gate valve, butterfly valve, check valve, globe valve, ball valve, trap valve, safety valve, etc. all valves

Q: What does "41H" mean in the ball valve Q41H-16?: Q- ball valve;4- flange connection;1- through flow channel; (structural form)H-Cr13 stainless steel; (material)16- nominal pressure; (1.6Mpa)Body material: WCB, A105This is manual, and the valve body is WCB.

Q: Ball valve, PTFE pad inappropriate choice, is not easy to bad ah?: 120 - 150. TemperatureChasing the answerYes, but not in a high temperature for a long time, like more than 180 degrees centigrade. Because the gasket can not be used after deformation, it will cause valve leakage.
