Q: About the characters on the ball valve (what do s and O mean?): That's almost what it means. To be exact, S is SHUT and O is OPEN

Q: O ball as general regulation of opening extent: According to the actual demand, turn 90 degrees from the closed state to the maximum opening.

Q: What is the difference between ball valve and butterfly valve?: The two kinds of valves can be distinguished from their names. Ball valve cut-off is a ball in the valve to achieve, the ball blocked the pipeline will not flow, move away on the circulation. The closing effect of the butterfly valve is two or one butterfly wing, just like butterfly wings, or, like a blade, the shop is expanded and sealed, and the pipe is out of circulation. Plainly, one is blocking with the ball, and the other is blocking with the blade.

Q: Would you please tell me why the spring is placed in the valve seat? What's the function?: Valve seat on both sides should be added spring, the seal pushed to the valve core to seal up, so put the spring.

Q: What is the nominal pressure 1.6p of a ball valve?: Nominal pressure PN is a digital indication of pressure related signs, which is a convenient round integer for reference. All pipe attachments of the same nominal diameter indicated by the same nominal pressure PN have the same connection dimension as the end connection type.

Q: What are the structural shapes of the eccentric hemisphere valve, what are their respective characteristics?: Structure and characteristics of eccentric hemisphere valve1, a type: mainly for erosion is very serious in the medium, upper structure replaced maintenance loss of the opening and closing member is very convenient, without the whole valve removed from the pipeline, greatly saves the maintenance time and cost.2, side mounted: side mounted compact structure, valve quality light, applicable to the valve installation space requirements, the light valve of the leading product seems to be eccentric hemisphere valve!

Q: What are the CF8 and CF3M marks on the stainless steel ball valves?: Hello, CF8 stands for 304 material, and CF3M stands for 316L material. It's stainless steel

Q: Under what circumstances with the butterfly valve, under what circumstances with the ball valve?: Butterfly valve for occasions:Butterfly valve is suitable for flow regulation. Due to the pressure loss of the butterfly valve in the pipe is relatively large, is about three times the gate, so the choice of valve, the piping system should fully consider the influence of the pressure loss should also be considered robust when closing the butterfly plate to withstand the pressure medium pipeline. In addition, the operating temperature limit of resilient seat materials must be taken into account at elevated temperatures.Butterfly valve structure length and overall height is small, open and close speed is fast, and has good fluid control characteristics, butterfly valve structure principle is most suitable for making big mouth valve. When the butterfly valve is used as a control flow, the most important thing is to choose the size and type of butterfly valve so that it can work properly and effectively.Usually, in throttling, adjusting control and slurry medium, the structure length is short and the opening and closing speed is fast (1/4 rpm). Low pressure cut-off (small pressure), butterfly valve is recommended.Butterfly valves can be used in double adjustment, necking channels, low noise, cavitation and gasification, with little leakage to the atmosphere and corrosive media.

Q: What's the meaning of the ball valve bore 14 "x 12"?: Should refer to imports 14 inches, export 12 inches, this kind needs to make to order, at present domestic possibly not yet.

Q: Ball valve, PTFE pad inappropriate choice, is not easy to bad ah?: PTFE gasket is mainly resistant to high temperature, easy aging, but the use of such soft sealing gasket, ball valve sealing performance.
