Q:What does copper ball valve mean by "1/2"?

1/2 is inch inch, which is what is usually called "valve", and the caliber is "DN15". You can see the contrast chart of the valve diameter and inch.

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's the difference between a copper ball valve and a stainless steel ball valve?

The difference between copper ball valve and stainless steel ball valve:1, they use the material is completely different, steel ball valve adopts copper, stainless steel ball valve is stainless steel.2, copper ball valve corrosion resistance is excellent, switch operation is smooth, labor-saving, durable without leakage. Stainless steel will not cause corrosion, pitting corrosion, corrosion or wear, and high temperature resistance. The average stainless steel is more expensive.3, according to the same pressure environment, the price is stainless steel cheaper, and copper ball valve medium temperature is much higher than the stainless steel ball valve, if the medium temperature is too high. Copper ball valve must be used! If the medium temperature is not more than 80 degrees. With stainless steel ball valve on it

Q:Is the two piece ball valve in the direction of the pressure pipe?

Compression capacity is not as good as two, but better than the three chip. A ball valve has the advantages of low cost, low price; the two valve is the three products in the most excellent in resistance and flow, the valve inside is preferred; features three ball valve design structure is easy to install, because the three ball valve can be installed by dismantling during installation, so in different pipeline even some other connections are completely no problem, fast loading, thread, flange, welding and so on, so the market is the most complete connection number of ball valve, especially when welding, a chip ball valve and the two valve can not be opened due to installation, want to welding in the pipeline it would be easy to the inside of the PTFE (similar to plastic) in a burnt out, the best choice at this time is three piece ball valve. But the disadvantage of three piece ball valve is the poor compression ability.

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:Can the check valve replace the ball valve?

Can not be replaced, because the ball valve to play a maintenance, cut off the role of water sources

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:Maintenance of PPR pipe ball valve is live or hot melt?

In our country, ball valves are widely used in petroleum refining, long-distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electricity, municipal, steel and other industries, and occupy a pivotal position in the national economy. 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.Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of media flow, it only need to rotate 90 degrees of operation and a small rotating torque can be closed tight. Ball valve is the most suitable switch, shut-off valve used, V ball valve. Electric valve should pay attention to the pipe parameters, but should pay special attention to its use of environmental conditions, because the electric valve in the electric device is a mechanical and electrical equipment, the use of its state by its use of environmental impact. Under normal conditions, electric ball valves, butterfly valves in the following environmental use should pay special attention to.

Q:DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?

Supplement: the above mentioned is just a pure design, such as the novice to do the design, checking and calculating of the general will, in fact in the reality of the design, the valve products have been very mature, as you say these are size, can refer to the same type with the specifications of the product parameters so, the more accurate calculation, experience is more important than calculation.

Q:What is retractable hemispherical valve? What's the area with the manual hemisphere valve?

Telescopic hemisphere valve is a telescopic hemisphere valve, ordinary hand hemisphere valve, of course, without expansion joints.Telescopic ball valve is a combination of expansion joint and ball valve. It has the telescopic deformation caused by heating and absorbing the axial, transverse and angle of the absorption pipeline. Absorb the vibration of equipment and reduce the influence of equipment vibration on pipeline.
