Q:What is the difference between valve j941H-40 and j41H-40?
Valve design manual showsJ- stop valve9- electric4- connection means flange connection1- through typeH- sealing surface is alloy40- operating pressure is 4.0Mpa (or 40 kg)According to the comparison, we can see that the difference is that one drive mode is electric, one is transmission mode, and the other is manual. What do not understand, you can ask me directly. Two hundred and fourteen million two hundred and seventy-seven thousand eight hundred and fifty-one
Q:What valve is the DN 25?
That is, the inner diameter of the valve is 25 millimeters
Q:What does the "PN" mark on the valve mean?
The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)
Q:What kind of valves are best used for sand drain valves?
Looking at the domestic sand discharge conditions, the more commonly used plate valve and butterfly valve these two, but generally reflect the service life is not long, it will not be long before the sand leakage, the need for regular maintenance, low efficiency, affecting production. In recent years, the industry has also appeared in various kinds of new type of valve, take little effect, but also has a valve using the excellent response, talent shows itself, long service life, no maintenance, model for the special valve industry Yu powder FQD672 and FQD643,It is understood that the valve industry has been to focus on Yu powder (sand) on body condition, especially the delivery of viscous pneumatic conveying system, special valve type FQD672 and type FQD643 powder successfully developed specifically for the design of sand material conditions, erosion resistant, anti adhesive seal design, automatic compensation, to ensure zero leakage absolutely, efficient and longevity, is applied to the resin sand casting industry (coarse sand) sand core shape of the high-speed exhaust conditions, you can try to understand Baidu......
Q:Which brand of electric valve is good?
Taiwan mountain, South Korea I-TORK are good. The mountain is characteristic of the hand wheel device, the hand wheel device is without clutch design, when the current is interrupted, without using any auxiliary tools (brake wrench, etc.) under the condition of the manual operation valve handwheel will directly to the desired position, and when the normal power supply, not because of misuse the hand wheel caused personal injury or cause drive failure.
Q:High and low pressure valve is how to distinguish?
Vacuum valve - valve with operating pressure below standard atmospheric pressure.Low pressure valve - nominal pressure PN is less than 1.6MPa valve.Medium pressure valve - nominal pressure PN 2.5~6.4MPa valve.High pressure valve - nominal pressure PN10.0~80.0MPa valve.Ultra high pressure valve - nominal pressure PN greater than 100MPa valve.
Q:Is there any problem with connecting the geothermal valves with other geothermal pipes?
Yes, as long as it's all PPR's.Material is the same, the fuse will not cause shrinkage when you can use
Q:How much is the 150LB of the valve?
150Lb=2.0MPa=20 kg.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications.
Q:Heating pipes, in addition to the living room,
You just put the living room off the water inlet valve, open the drainage valve with backwater top a try
Q:What does the "XV" valve mean?
XV:X said V is plug valve, said valve body material is chrome molybdenum vanadium steel.
