Q: What does "C" in D971F-16C DN450 RF mean for electric butterfly valves?
C represents the valve body and the material is cast steel;D stands for butterfly valve; 9 stands for electric; 7 stands for clip type; 1 represents middle line butterfly valve; 16 stands for nominal pressure 1.6Mpa; RF stands for flange joint; in the form of protruding surface.
Q: Butterfly valve flow direction is single or two-way?
The arrow on the butterfly valve is the medium direction of circulation, generally double eccentric, and the three eccentric butterfly valve has the arrow in this direction.The butterfly valve, the valve direction and fluid flow direction should be consistent, we use the butterfly valve is in accordance with the arrow direction and flow direction of the installation.If the arrow is marked on the valve body, it must be installed in its direction. If it is marked on the handle, it means open. Depending on the internal structure, it is possible to have the installation direction required.
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
Both are powered by electric butterfly valves.The control valve must have the ability to accept external signal control. At the same time, control signals and valves through the medium flow must ensure a certain relationship.Electric control valve belongs to electric butterfly valve; electric butterfly valve butterfly valve including but not exclusively butterfly valve.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: How warm is the PTFE butterfly valve?
The normal temperature can be kept at 120 degrees and the instant temperature is 150
Q: I have put a new pressure valve and replaced both thermostat
so that should have fixed it I wonder if you needed to replace the stats
Q: Specifically an engine valve retainer.
TRhe retainer and locks works together to hold valve to spring and keep valve from falling into the cylinder and spring from coming off the top. The locks are tappered, small end at bottom, big end at top. You compress the spring down, drop retainer over valve, put locks in groove of valve stem and pull up on the retainer to lock the retainer and locks in place, the relese the pressure off your spring compressor and the valve spring now holds pressure up on retainer which forces up on the big end of locks and holds everything together
Q: Whenever sports cars are referred, people talk in terms of 'valves'. ex: v8, v12 etc. What does this all mean? Also they sometimes say that a v8 makes a great noise. why? How does the number of valves effects the performance? Many thanks.
the v is in reference to the motor its in a v formation v8 4 cyliders on each side v6 3 per side v12 6 pre side now the valves is how many are in each cylinder you usually have 3 or 4 valves per cylinder the more valves the more horsepower the more cylinders the bigger the engine
Q: What is the difference between wafer (flangeless) type and LUG type of butterfly valves?
WAFER butterfly valve is the valve is divided into LUG (ears) with and without LUG, ordinary LUG without clip on 12 points in the direction of valve is generally two to four bolt holes was not, whereas the LUG of butterfly valve cross dispersed in a circle. Bolt hole. With LUG all bolted through the LUG, so that the butterfly valve and the clamp on the two flange connection is more solid, you check the valve picture, it is easy to understand
