- Q: Butterfly valve use
- Butterfly valve (English: butterfly valve) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role.

- Q: How can I get the fire signal butterfly valve?
- After the switch is closed, the alarm is output through the output module.
- Q: Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?
- Hard seal butterfly valve in any case, the reverse loading will cause tight seal.
- Q: Function of signal butterfly valve in fire sprinkler system
- The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance; two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.Wet alarm valve at the front of the signal butterfly valve with the main floor of the main role of the butterfly valve, first, maintenance, and two is the prompt sprinkler system, there is a signal butterfly valve closed, should be repaired as soon as possible.
- Q: How is the lug butterfly valve connected to the flange?
- It is clip type butterfly valve.Connection way is to use butterfly flange flange.The sealing surfaces at the ends of the two rubber sealing rings are respectively butted with the welded flanges welded on the pipe; the two headed screws and the nuts are used for fastening.
- Q: valve adjustment 2001 chev prism 1.8L
- valve adjustment . you need to know the fire order. the gage between the stem. rotators the cranshaft. it could be cold start. cylinder need to be bottomed center.
- 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: My quot;check engine soonquot; light came on yesterday and soon after that I took it to the nearest Midas to have the diagnostic test run on it - they stated I needed an ERG valve. I have no clue what it is and was told that it could run $160. - $300. for my 1900 Astro van. what is an ERG valve? I have noticed that my van has a low humming sound when I'm driving it.
- If initially the codes confirmed that the EGR valve grew to become into defective and grew to become into no longer replaced this might smash the o2 sensor. whilst the EGR is caught open simply by fact of carbon strengthen the engine is taking in extra air it is coming from the blistered gases out of the exhaust and re burning them interior the process the EGR. The O2 sensor will examine this gases passing interior the process the exhaust and point out a lean mix of gasoline and could sign the ECM to strengthen the gasoline to the engine nsequently after a time of employing with mistaken mixtures the o2 sensor will fail. My suggestion is to change the EGR and the O2 sensor then highway try the vehicle.then have the codes rechecked. additionally if the engine isn't working mushy this might reason the transmission to act up.verify that the vacuum hose is linked to the modulator valve on the decrease back of the transmission. some transmissions have a working laptop or computer on a separate circuit interior the device and if the engine isn't working solid computer will p.c.. up the incorrect sign and transmission won't shift properly.. solid good fortune oh and the vehicle ECM or computer isn't your difficulty.
