Q:Stainless steel ball valve, Q11F-10P, 16P, 11F, what does that mean?

The first 1 that connect the second ball, 1 straight through valve, F PTFE sealing.

Q:What does "ball pq340h-10c-1200" mean?

This is the worm gear eccentric hard seal hemisphere valve, 10 kilograms of pressure, caliber is 1200.

Q:What is the principle of forced sealing ball valve? How to achieve mandatory sealing function? Is it suitable for high pressure conditions?

Structural characteristicsForced sealing ball valve combines the advantages of ball valve, gate valve and plug valve. It has the characteristics of good tightness, no wear and tear, erosion resistance, and on-line maintenance.(1) the bevel of the lower end of the forced seal lift stem provides a mechanical wedge tightening force to ensure continuous tight seal.(2) switch no wear, valve switching process, the ball deviates from the valve seat and then rotating, eliminating the friction of the valve seat, to solve the ordinary ball valve, gate valve and plug valve seat wear.(3) the anti erosion lifting stem realizes the rotation of the ball from the valve seat, and the ball and the valve seat perform the switching action without contact. When the valve is open and about to be closed, the fluid flows immediately along the sealing surface in the range of 360 degrees. When the fluid begins to flow, it can flush the impurities on the valve seat. To avoid the high speed fluid in common ball valve opening and closing the micro moments of local scour on the seat, even the harsh conditions of high pressure, can still ensure long-term zero leakage and tight sealing, improve the service life of the forced sealing ball valve.(4) no case single seat design avoids the valve cavity pressure increases and easy to jam problem.(5) good sealing performance, the ball and valve seat sealing surface after special hardening treatment, can not damage the integrity of the seal to meet the very harsh conditions of sealing requirements.(6) easy maintenance valve adopts top mounted structure. After decompression, it can be checked and maintained online, and the maintenance is simplified.

Q:Under what circumstances with the butterfly valve, under what circumstances with the ball valve?

The flow control accuracy requirements are not high, the fluid pressure is small place with butterfly valve, butterfly valve is the simplest kind of valve, mainly used in regulating the air flow and powder flow!According to the pressure of the liquid and gas fluid control, flow effect, rapid opening and can completely cut off for flow with the ball!

Q:Ball valve Q41f and Q11f difference, whether universal?

Yes, it works,The main valve interface shall be in line with the interface on the pipe,No, the valve is a thread, and the pipe joint is flanged, so it won't work.

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:For our valve beginners, how intuitive decision is floating ball valve or fixed ball valve?

Floating ball valves and fixed ball valves can be located in the lower stem position, if there is a lower stem is fixed ball valve

Q:What does telescopic ball valve mean? What does it mean?

Telescopic ball valve, simply said that the ball valve plus telescopic structure, as a compensation and shock absorption role.

Q:Flange ball valve Q41P3-150C2, DN50, RF, WCB/316 hardening, each letter number represents what?

P3, C2? Uncultured, I know P and C, P is the sealing surface material boroning steel is above C, WCB or A105But you Tidianyijian pressure 15MPa, RF surface is not well, the best is to use RJ flange

Q:Ball valve? I require the valve to control both sides of the liquid, one side with liquid flow, and the other side closed!

This is a manual ball valve three simple when meet your requirements is L ball valve
