A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and wafer type butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc that is droved by actuators.
1.Simple and compact construction. Small in size and light in weight. Easy transportation, installation and maintenance.
2. Quick 90 degrees on-off operation. Minimized operating torque ,energy saving.
3. Excellent sealing performance with no leakage. Long service life.
4. Wide selection of materials ,applicable for various media..
5. Flow curve tending to straight line. Excellent regulation performance.
- Q: What's the difference between the three eccentric butterfly valve and the two 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. 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.
- Q: Ok, so I took my car in for maintenance (Mustang GT convertible 2002) and the mechanic told me the valve gaskets needed to be replaced and when he gave me the estimate, they were two seperate charges for valve gaskets and valve covers, total of about $250.00 not including labor. Is he trying to rip me off cause I'm a girl by the way? Anyways, I didn't get it done cause it needed something else too and I didn't have enough money so I said I would be back in two weeks. So I called the dealership to inquire about the price and I asked the parts guy for a price on valve gaskets and he was like, I don't know what you mean, we have valve cover gaskets but nothing says just valve gaskets? I told him to give me the price anyways, thinking I would ask my brother (who hasn't tried to help me anyways) and it was $60.00 for both (I need two). How can this be if the other guy was charging me $250.00 for different parts? Help!!! Frustrated and confused, I don't know anything about cars :(
- Your car has 2 valve covers hence,2 valve cover gaskets. Not valve gaskets. Maybe one of the valve covers needs replacing? If the valve covers or gaskets need replacing your car will be leaking oil from under the hood.
- Q: The difference between butterfly valve and gate valve
- Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.
- Q: Butterfly valve flow direction is single or two-way?
- To see your butterfly type low voltage soft sealing clamp / flange butterfly valve is a two-way flow; and high pressure valve seal to choose clip / flanged butterfly valve, these are single direction flow, the valve body is provided with a flow indicator! There are so many factors that you have to say, such as working conditions, pressure, temperature, design concept and so on.
- Q: What is the electric butterfly valve? Please, great God!
- Therefore, this butterfly valve is the best matching product of automatic fire sprinkler system. The structure characteristics and working principle: the top design electrical device the butterfly valve of the worm and the worm gear driving device, and with the stem straight connecting transmission. In the closed precision electromechanical device, opening mechanical instructions and imported electrical components and parts with rust proof valve.
- Q: What does butterfly valve nps12cl150d373f4-150lb stand for?
- NPS (Nominal, Pipe, Size) abbreviation. Refers to the connection (including flanged and welding end) of the nominal diameter, followed by a digital unit is American Standard inches, 12 inches.NPS12 labeling system.CL is the abbreviation for class, and LB150 means the pressure is 150 poundsD stands for butterfly valves3 is expressed in the form of a turbine drive7 means of connection: to clip3 means sealing: 3 eccentricF4: the sealing material is PTFE
- 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: I have put a new pressure valve and replaced both thermostat
- If it is not overheating due to a stuck thermostat or bad heating element and you changed the TP valve then it is possible you have a problem with thermal expansion. When water is heated it expands and the more it is heated the more volume it will need to expand. Since the water heater and the piping are not designed to expand the water only has one place to go (well two if count the faucet) and that is out the TP valve. This problem is not uncommon and the solution is to have an expansion tank installed on the hot water heater in the piping near the tank.
- Q: What are the butterfly valves models?
- Sealing surface material score:(1) soft sealing butterfly valve.1) the sealing pairs are made of non-metallic soft materials, which are made of non-metallic soft materials.2) the sealing pair is made of metal hard material and is made of non-metallic soft material.(2) metal hard sealing butterfly valve. The sealing pair is made of metal hard material and is made of metal hard material.According to the form of sealing:(1) forced sealing butterfly valve.1) elastic sealing butterfly valve. The pressure of the valve seat, seat, or plate is produced when the seal is closed by the pressure from the valve.2) additional torque seal butterfly valve. The seal is produced by a torque that is applied to the valve shaft.(2) pressure sealed butterfly valve. The pressure is greater than the pressure on the seat or plate.(3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium.
- Q: For example, the arrow above is from left to right, and the direction of my current is from right to left. Is that ok? I have a diameter of 700 of the hard seal butterfly valve is so installed, but it will leak water, it will not leak, very serious
- The direction of the arrow on the valve body is cast, refers to the flow of media, users see the arrow, the arrow direction according to the logical and installation, this installation has become a habit, it is easy to accept the installation instructions, according to the national standard is not what error. But in the eccentric butterfly valve is installed so that sometimes there will be some problems, said the following example: according to the flow of eccentric butterfly valve with the medium flow consistent installation, tube medium is liquid, after the valve is closed, if the original direction of medium inlet pressure, reduced or zero, the export of medium reflux reflux, if senior supply, resulting in the high pressure medium, the pressure is greater than the inlet pressure, the valve will be subjected to reverse pressure, because the hard seal butterfly valve as a one-way valve so that the use is not conducive to sealing butterfly valve, and there will be leakage.
