Q: What are the uses and characteristics of copper ball valves?: 4, good sealing performance5, the direction of installation is not limited, the flow of media can be arbitrary

Q: What does "F" and "C" mean in the Q11F-16C of the ball valve?: This model is not international standard number, but still can see, of which, F refers to the sealing material: fluorine plastic, C refers to the body material: carbon steel.

Q: What does W represent in copper ball valve Q11W-16T?: According to the provisions of the JB/T 308-2004 valve type programming method:Q== ball valve1== connection: internal thread1== ball valve structure: straight through flowW== sealing surface material: body. That is, the sealing material is the same as the body material-16== pressure rating: 1.6MPaT== body material: copper or copper alloy

Q: What does "DN PN" mean? DN25 PN18 stands for what is the thickness? With the usual said 4 in charge of what's the relationship?: *DN25 nominal diameter 25MM*PN18 nominal pressure 18 kg / cm2

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: Please professional help guide: accidental discovery of connection pipe and valve (mark position diagram) can rotate, but there is no problem with the 10 Water Leakage.Please professional help guide: accidental discovery of connection pipe and valve (mark position diagram) can rotate, but there is no Water Leakage problem, while the valve under the same position is fixed and can not rotate, will this situation is normal? Is it possible to leak water in the future?: This situation is not normal, the reason is not between the upper PVC pipe and tighten the valve, now has been unable to tighten, in order to avoid the emergence Water Leakage situation, you can use a silicone rubber sealing between the valve and the pipe to be dry silica gel between the pipe and valve after no loosening of the situation.

Q: What is the diameter of the 2 inch ball valve?: It depends on whether your ball valve is full diameter or necking

Q: 3/4 on the elbow of the water pipe. How about that ball valve?: 3/4 inches converted approximately equal to 20mm, that is, DN20, can be equipped with DN20 caliber ball valve, commonly used for brass material

Q: What is a high handle ball valve? What's the difference between it and ordinary ball valve?: the valve handle can extend out of the insulation material, convenient operation.

Q: What are the CF8 and CF3M marks on the stainless steel ball valves?: The valve body material. With the material composition American Standard... See the relevant information
