- Q: What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?
- Depending on the size of the valve and the opening and closing torque, the transmission mode is different (handle or turbine).
- Q: How warm is the PTFE butterfly valve?
- The normal temperature can be kept at 120 degrees and the instant temperature is 150
- Q: Do you use the straight stem butterfly valve in the fire fighting engineering?
- Bar valve bar, did not hear the bar with butterfly valve, ah, there are pairs of folder and hand wheel type bar
- Q: What are single eccentric and double eccentric in butterfly valves? What's the difference, please explain in detail?
- Eccentric butterfly valve is divided into single eccentric butterfly valve, double eccentric butterfly valve, three eccentric butterfly valve, variable eccentric butterfly valve.Single eccentric butterfly valve: extrusion problems, address concentric butterfly valve and valve seat of the resulting in a single eccentric butterfly valve, the structural characteristics of the stem axis deviated from the disc center, so that the butterfly is no longer a rotary bottom plate, axial dispersion, reduce the excessive squeezing and the lower end of the seat of the butterfly board.
- Q: Butterfly valve switch direction respectively?
- If there is no arrow on the handwheel, the indicator on the turbine has been damaged, you can put your ear on the wall of the pipe, turn the handwheel, and through the sound of the pipe medium to determine the direction of the switch.
- Q: Specifically an engine valve retainer.
- Valve Spring Retainer
- Q: Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
- Three eccentric hard seal butterfly valve quality standards, up to zero leakage, but you mean the end of the direct discharge?If so, that's OK. First you have to calculate how much the pipe fluid pressure is.For example, the pipe fluid pressure is highest and the pressure is 1.6MPa (16 kg)Should choose three eccentric hard seal butterfly valve should be pressure 1.6MPa (16 kg)If you worry, optional 2.5MPa (25 kg) will not leak!Answer: three eccentric hard sealing butterfly valve can be installed at the end of the pipe
- Q: Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
- D stands for butterfly valve. 71 represents the clamp type, X represents the sealing surface material, and 16 represents the valve to bear the pressure 1.6MPA, C position is the valve body material code, omitted to represent gray cast iron valve; C represents the valve body material is carbon steel.
- Q: Which is more expensive, gate valve or butterfly valve?
- Gate valve.Under normal circumstances, if you need to adjust the good point, to use the gate valve, and if better, you can choose the cut-off valve.But the price is also butterfly valve, gate valve, globe valve increasing.
- Q: Buried extension butterfly valve is buried or need to repair the valve well, can build the valve well, the extension rod butterfly valve installed in the valve well, the extension rod to avoid covers, the top of the valve well out, so that the hand wheel in the ground operation.Atlas S143 is less than the inner diameter of DN150 valve wells only 1200mm, DN200-DN250D diameter of only 1400mm, 700mm valve covers, valve rod and a handwheel to lengthen through the valve cover, valve wells is built to cover the embedded pipe or tube? Is there a standard atlas?
- The establishment of a repair valve well, easy to repair, usually hydrogen long rod butterfly valve installed in the well. But if the quality of buying long stem butterfly valve, it can also be buried directly, not easy to bad
