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:Are ball valves and float valves a thing? If not, what valves belong to the valve, screw valve, threaded flange valve, welding flange valve or flange valve?.Online, etc.. Thank you: Ball valve and float valve is a kind of valve, the ball valve is a valve inside the ball, it is called the ball valve

Q:Domestic water pipe ball valve or cut-off valve?: Stop valve: switch process to rotate a lot of laps, adjust the flow size better than the ball valve.

Q:PE pipe size diameter 3/8, diameter 1/4, material: low density polyethylene, pressure 170psi;Valve material: copper, and PE pipe connection interface with lock nut.Is this connection reliable? Will the pipe break due to excessive compression? Are there any requirements for the size of the joint and the size of the nut?: First, 170psi pressure is not great, not excessive extrusion and rupture of polyethylene, but there will be stress relaxation phenomenon, is a long time there will be some loose, suggest you nut and pipe with tight mechanical connection is good, the data has not been studied, can only give you a suggestion: 24-48 hours after the installation is complete then a proper tight.

Q:What does the RTFE say in the ball valve?: RTFE reinforced PTFE is more wearable than PTFETeflon PTFEThe seat of tetrafluoroethylene specified for a temperature range of ~200 DEG C -32. High temperature resistance and chemical resistance. Because of its high density and good permeability, PTFE can also prevent the corrosion of most chemical media.Conductive PTFE is an improved PTFE product that allows the current to pass through the lining and thereby cancel the insulation properties of ptfe. Because of its conductivity, conductive PTFE can not be checked by edm.+ reinforced PTFE RTFERTFE is a modification of PTFE material. Pure PTFE although very low coefficient of friction (0.02~0.04) but the wear volume is great, but also because of its easy creep, poor mechanical properties, low bearing capacity, poor dimensional stability characteristics such as friction material has great localization. Only modified by compound method to meet the special requirements of all walks of life sealing material on the wear resistance, to improve the wear resistance of PTFE, can be incorporated into some wear-resistant materials such as glass fiber, carbon fiber, graphite, molybdenum disulfide, bronze powder and some organic compounds, making them reticular junction formed in the PTFE layered structure so as to improve the the stiffness, thermal conductivity, creep resistance, and greatly improve the wear resistance.PTFE is composed of tetrafluoroethylene monomer polymerization of the polymer, the wax is similar to a PE transparent or opaque, its density is 2.2g/cm3, the water absorption rate of less than 0.01%. Its chemical structure is similar to that of PE, except that all hydrogen atoms in polyethylene are replaced by fluorine atoms. Because the C-F bond is high and stable in performance, it has excellent chemical resistance

Q:Ball valve? I require the valve to control both sides of the liquid, one side with liquid flow, and the other side closed!: Three way reversing ball valve. Three way ball valves are T and L. The T type can cause three orthogonal pipes to connect with each other and cut off third channels, thus diverting and merging the channels. Two pipeline L three ball type valve can only be connected mutually orthogonal, communicating with each other while maintaining the third pipeline, only as a distribution function.

Q:How does ball valve indicate?: Start with Q, such as Q41F-16P DN50Q is a ball of the code, second bit 4 is connected, third bit 1 is the structure form, the F fourth is sealing surface material is PTFE, 16 represents the pressure is 16KG, P stainless steel,,Specific refer to valve selection manual,,

Q:Is the stainless steel ball valve forged steel ball? Which one is suitable for the gas pipeline? (FAQ: This does not mean cast steel can not be used. Cast steel is also acceptable because all the check valves and control valves of natural gas lines are cast. But the casting process has a high probability of defects.

Q:What is the maximum temperature resistance of the 304 stainless steel ball valve?: What seal do you have?.PTFE sealing maximum temperature: 120 degreesMetal seal maximum temperature: 325-400 degrees, look at the manufacturers.

Q:Ball valve use?: The utility model has the action of rotating 90 degrees, and the cock body is a sphere, and has a round through hole or a passage through its axis.
