Q: Is the stainless steel ball valve forged steel ball? Which one is suitable for the gas pipeline? (FAQ: For example, the relationship between CF8M and F316.Natural gas pipelines look at bore, pressure, temperature, and composition.Clean natural gas with ordinary carbon steel ball valve on the line.Material basically A105N, LF2 based.As for pipes, I don't need to forge steel. My suggestion is that they should be made of forged steel.

Q: Butterfly valve, globe valve, ball valve used what is different: Butterfly valve, globe valve, ball valve used in different occasions:1. valve (Butterfly Butterfly) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closure of a valve, the main cut off on the pipe and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve.Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe.

Q: 1 piece, 2 piece, 3 piece ball valve, which places are used in large quantities?: Structural features of two piece ball valve:1, opening and closing without friction. This function completely solve the traditional valve because of the friction between the sealing surface and affect the sealing problem.2, top structure. The valve installed on the pipeline can be directly checked and maintained, which can effectively reduce the device parking and reduce the cost.3, single seat design. The utility model eliminates the problem that the medium of the valve in the valve is influenced by the abnormal voltage increase.4 、 low torque design. Special structural design of the valve stem, with only a small hand, the valve can easily open and close.5 wedge sealing structure. Valve is provided by the mechanical force of the valve stem, the ball wedge to the seat and seal, so that the valve sealing is not affected by changes in pipe pressure, in a variety of conditions, sealing performance has a reliable guarantee.6. Self-cleaning structure of sealing surface. When the ball roll off the seat when the fluid in the pipeline along the sealing surface of the sphere into 360 degrees evenly through, not only eliminates the high speed fluid on the seat of local scour, also washed away the sediment on the sealing face, achieve the purpose of cleaning.

Q: What is the ball valve core?: Ball valve spool is the ball, valve opening and closing parts (sphere) driven by the stem, and around the stem axis rotation. More ball material, carbon steel, forged steel, ceramics and so on.

Q: What does the sealing surface of the ball valve stand for HF?: HF is the abbreviation of two English words: "Hard Face", which means surface hardening. Usually surfacing is made of Tailai alloy (Alloy 6). Other surface hardening methods include hard chromium plating. This method is used more in the ball valve. But hard chromium plating is prone to small cracks, which reduces its corrosion resistance.

Q: What are the structural shapes of the eccentric hemisphere valve, what are their respective characteristics?: I. structural form:The eccentric hemisphere valve is divided into two kinds in its appearance and structure:The coat 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.Side mounted: side mounted, compact structure, light quality valve, applicable to the valve installation space requirements.

Q: What is the difference between gas ball valve RQ11F-25P and ordinary stainless steel spike valve Q11F-25P?: The models are all the same. What's the difference? Q ball valve, 1 internal thread, 1 floating through type, F PTFE sealing, 25=2.5mpa, P stainless steel.

Q: Must I use the ball valve for the heater?: Valve main points and angle valve, ball valve in the water pressure is large enough to use, angle valve can increase the pressure of a little water.
