Q: Why anti condensation of aluminum alloy anti condensation butterfly valve?: Anti condensation butterfly valve principle: the use of the high performance plate material, can effectively prevent the temperature of body parts, isolating the transfer medium in the pipeline, to the actuator and the connecting flange surface without dew.

Q: How do you explain A in butterfly valve D37A1?: Represents a seal or lining material symbol.Said sealing ring or lining material with the Chinese phonetic alphabet: B Babbitts D nitrided steel, acid resistant stainless steel H, J L Aluminum Alloy, hard rubber, nylon NL, P leather, SA PTFE, SC PVC, SD bakelite, T copper, TC enamel, X rubber, Y hard alloy

Q: Gate valve and butterfly valve which is installed when there is a direction?: Do not require frequent opening and closing, and keep gate fully open or fully closed. Not suitable for use as a regulator or throttling.

Q: Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?: Our factory butterfly valve has two-way sealing, can be installed, and will not leak. If there is an arrow above the butterfly valve is one-way seal, that is, can not be installed. One way sealing will cause leakage. If you have any other questions, you can bring them up. Let me help you with that

Q: How is the lug butterfly valve connected to the flange?: When installing, pay attention to the butterfly plate. The sealing ring between the flange face and the butterfly valve is tightened. After clamping, it can be tightened.

Q: What are single eccentric and double eccentric in butterfly valves? What's the difference, please explain in detail?: Double eccentric butterfly valve: in the single eccentric butterfly valve on the basis of further improvement of forming, is the most widely used double eccentric butterfly valve. The structure features that the center of the stem deviates from the center of the disc as well as the center of the body. The effect of the double eccentric valve can be opened immediately after the disc from the valve seat, substantially eliminating the unnecessary disc and valve seat over squeezing, scratching phenomenon, reduce the resistance from the open, reducing the wear and improve seat life.

Q: Should I connect the butterfly valve before and after the pump? Or gate valve?: Personally believe that import and export butterfly valve or gate valve can be, or other valves. One principle, easy installation and easy maintenance.As for how much pressure can be selected according to the size of the pump flange to set the general small caliber pump are 1 and 1.6 pressure general, unless you are a super high pressure multi-stage pump, generally 1 flanges fully meet the requirements of pump working pressure is generally not too high, living above the water temperature will not exceed 40 C, so you choose the space is still very large.

Q: What do you mean by manual butterfly valve DN100 D341X-10?: DN100 refers to the inside diameter of the butterfly valveD stands for butterfly valves3 represents the turbine drive4 represents the flange connectionThe 1 represents straight throughX is the representative of the Dengqen rubber seal10 represents the pressure of 1.0Mpa (10 kg)Manual butterfly valve, also known as turn over plate valve, is a simple structure of the control valve, but also can be used for low pressure pipe medium switch control. Butterfly valve refers to the closure of parts (valve or butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.

Q: What are the functions and uses of butterfly valves?: Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear.Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve.

Q: I have a good set of #142 Pontiac heads with small diameter valves. I want to have the heads enlarged to accept the larger Pontiac valves, and I have the larger exhaust valves out of #13 heads and the larger intakes from 6X8 heads. The valves appear ok and shiny on the stems: If the valve is burnt there is no longer something you're able to do with it yet replace it. in the event that they simply desire cleansing up you could lap them in with a lapping compound the threat with this is which you would be able to desire to visual exhibit unit which you don't get close to to the sting of the valve, this is once you will finally end up with a burnt valve. The valve should not be flush with the valve seat this is plenty to close and the warmth of combustion could have an more advantageous effect on the textile.
