Q:Hello, the valve material is 3Gr13, stem 3Gr12, I would like to ask, this valve against sulfur?
3Cr13 martensitic stainless steel, C content is relatively high, if the S is dry, corrosion resistance is relatively small, with 3Cr13 not what big problem, if the water is single, cannot use 3Cr13,
Q:Can aluminum alloy 6061 be used as stem?
Its main chemical components are:Cu0.15-0.4-, Si0.4-0.8, Fe0.7-, Mn0.15-, Mg0.8-1.2-, Zn0.25-, Cr0.04-0.35-, Ti0.15-,Our distribution: Alcoa "ALCOA" brand. The varieties of T6061-T6.T651, A5052-H32, T7075-T651110010506063508320112014201720243003508662627050 alloy aluminum rod / tube / wait, our commitment: the same product, cheaper,The same price, better quality,The same quality, better service.&nbs specific contact Mr. Ke answer for you
Q:What is the effect of the gap between the solenoid valve and the valve stem?
Basically does not affect, you can install it, you can look at the adoption
Q:What does the stem material VTA mean?
At the same time, it is subjected to the impact and corrosion of the medium, and it also causes friction with the packing. Therefore, in selecting the stem material, it must be guaranteed that it has sufficient strength at the prescribed temperature, good impact toughness, scratch resistance, corrosion resistance.
Q:How is the diameter of the valve stem determined?
In the valve manufacturing and production process standards, valve type, valve torque and valve stem diameter has a direct link.AskCan you say something about it, for example, the regulating valve?.Chasing the answerASME related standards, as well as GB GB standards relating to valve manufacturing.
Q:On the butterfly valve, the stem has single axis, no pin and double shaft without pin.
In the soft sealing butterfly valve, no pin valve shaft, there are two main ways of connection: 1, through the shaft without pin, 2, double shaft without pin, through the shaft without pin, in the design is the most basic method, design simple. When the shaft is machined, the double half shaft has a certain degree of difficulty in making it.
Q:What are the connecting ways of valve plate and valve stem of gate valve?
Valve advantages:1, small flow resistance. Inside the valve body, the medium passage is straight through, the medium flows in a straight line, and the flow resistance is small.2, when opening and closing more effort. In comparison with the cut-off valve, the gate movement direction is perpendicular to the direction of the flow of the medium whether it is open or closed.3, high height, long opening and closing time. The opening and closing stroke of the ram is larger, and the reduction is done by screw.4, the media can flow in any direction on both sides, easy to install. Gate valves are symmetrical on both sides of the channel.5. Compact structure, good rigidity of valve, smooth channel, small flow resistance, stainless steel and carbide alloy used in sealing surface, long service life, PTFE packing, reliable sealing, easy and flexible operation
Q:Chlorine valve, valve stem, valve spool are selected what material is better?
In fact, ordinary carbon steel, but chlorine special valve sealing better, specific you can ask about the production of chlorine valve manufacturers, chlorine, many things are national standard parts, very good buy
Q:Stem forging, this piece can be forged out of the whole, what equipment?
You see what material, similar in size, if the materials can be cold or cold extrusion, can be directly done, some alloy steel, not cold, hot forging can be processed, but the mold heat do more complex, precision is poor,
Q:Stem deformation of valve stem
The main stem has better compression, good thermal insulation, and is not easy to corrosion and rust, it has the sealing function of both sides, more resistant to abrasion and its long service life.
