- Q: 16 inches below the choice of electromagnetic valve can be the same, it turned out to be DN200 election 1/4, and now there are DN350 can also use this? With it, limiter, pressure relief valve, locator model will change?
- The valve (including the valve, butterfly valve, etc.) are equipped with pneumatic actuators are standard (including restrictor valve positioner of the electromagnetic valve is connected with the installation.) is the international standard NAMUR standards, in the standard of inside electromagnetic valve is G1/4, of course, this is the solenoid valve installation in the NAMUR interface of the driver on the situation, if the solenoid valve is not installed on the drive, but through the trachea installed in a few meters away, it would have to choose a larger size, how to choose? Depends on the switching speed of the valve requirements, such as drive gas consumption is 2L, need to open in 1S, the electromagnetic the valve requires the flow of 120L/min, plus the line loss and acceleration, 500L/min is enough.
- Q: What does the model D373H-16C of butterfly valve mean?
- D373H-16C said: D type butterfly valve butterfly valve 3 said, said 7 of the turbine, said clip, 3 said the three eccentric (swash plate), 16 C nominal pressure, said carbon steel. In fact, if you want to understand this, to understand the valve 3.07ghz, later met have to be attached to the valve. 3.07ghzModel for valves, valve number indicates valve type valve should normally be that type, drive type, connection type, structural features, nominal pressure, sealing surface material, body material and other factors. Standardization of the valve type of valve design, selection, distribution, provide more convenient. The type of valve types and materials are more and more more models of the preparation of the valve will become more and more complicated. Although the preparation of our valve type unified standard, but gradually can not meet the needs of the valve industry. At present, the valve manufacturer usually adopt a unified numbering; not uniform numbering, the manufacturer can make out no.methods according to their own situation. Unit two unit three unit four unit five unit six unit seven unit
- Q: The difference between the electric control valve and the electric butterfly valve, respectively, the application situation
- Electric butterfly valve is a kind of electric control valve.There are many types of valve body, usually through the single seat, straight through two seat, angle, diaphragm, small flow, three pass, eccentric rotation, butterfly, sleeve type, spherical and so on 10. In the selection of control valve valve prior to the media, process conditions and parameters to control the process of careful analysis, to collect sufficient data to understand the system requirements on the control valve, according to the data collected to determine the type of valve to be used.
- Q: I have a 1993 Oldsmobile Cutlass Supreme and I think I have the case of the blow-by. The engine had high mileage, but was rebuilt b/c it stalled while driving. 3.1L V6 gasoline engine. The fuel filter and the fuel pump are brand new. Now we have the same problem a few months later. It stalls while driving. Its been sitting a while and won't start by itself, so I pulled off the air intake hose off of the air filter to spray starting fluid into it. I noticed oil puddled in the air intake hose, so I looked for the PCV valve on the rocker cover. There is a tube going from the air-intake hose to the rocker cover. I popped out the tube from the rocker cover and there is no PCV valve. Just tube. Is that where the PCV valve is supposed to go? If not, where can I find it on the engine? And could that possibly fix the blow-by and the stalling engine? I'd appreciate any help. Thanks in advance.

- Q: What does the triplex of pneumatic butterfly valve mean?
- Generally referred to as "triple parts" as if: filter pressure reducing valve, solenoid valve, with the valve position feedback switch..
- Q: Butterfly valve model D373F-16C, ask God answers
- D butterfly valve, 3 turbo rotating, 7 pairs clip type, 3 eccentric F PTFE seal, 16 nominal pressure 1.6MPA, C valve body material, carbon steel
- Q: What is the butterfly valve
- Double valve technology is the use of large sets of small valve valve technology, place a small butterfly in the large butterfly valve, when feeding in a large number of double valves open at the same time, the material quickly added, when the material is in accordance with the set to a certain number, the valve automatically shut down, by a small valve to feed, until it reaches the requirements of the control system the number of closed, so as to ensure high precision batching material, thereby saving expensive raw materials.
- Q: Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
- The C indicates that the material is carbon steel and does not indicate cast iron (generally omitted)
- Q: Butterfly valve, two-way pressure and one-way pressure what is the difference?
- The positive pressure and the reverse pressure, the pressure when the medium returns
- Q: Butterfly valve is generally used in what position?
- Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, environmental protection, chemical smelting and power building water supply and drainage engineering system in conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow. It can also be used for switch control of low pressure pipeline medium.
