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 a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?
- Just drive differently,Handle butterfly valve is generally small caliber, because generally small caliber torque smaller, can be directly opened and closed by handTurbine butterfly gear box drive stem rotation.The selection principle for when the stem torque is greater than 300N.M when used in gear box drive gear box, and use the handwheel control hand wheel force is not greater than 300 nm.
- 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:The difference between gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?
- The gate valve is one of the simplest valves. Generally manual, most of the electric valve failure, as a manual. Butterfly valve is more, I saw the pneumatic butterfly valve, that is, with gas control closed, general and solenoid valve matching.
- Q:How to calculate the size of the manual butterfly valve?
- [1] type code, transmission mode, connection form, structure form, sealing surface material or lining material, nominal pressure, valve body material, this is the most basic arrangement way now D341X-16C. [2]: butterfly valve also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the air water, steam, and all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. On the pipeline, mainly from cutting and throttling. 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.
- Q:When i waa replacing the valves in the las 4 valves , they dropped and i dont know how to make them go back up, and i dont want to take the engine out of the car, is there any tool to make the valve go back up or there is any way to do it?? People told me that i can crank it by and , but i dont know how to do it where do i have to do it, i need help please im begging for help!
- You could use a socket and breaker bar on the bolt on the end of the crankshaft to slowly and carefully rotate the engine by hand. But if the valve is all the way down into the cylinder, the only fix is to remove the cylinder head. If you have been asking for days, maybe, just maybe, you are in over your head. Bring the car to a reputable mechanic and pay to have it repaired. Repeating the same question obviously isn't helping at all. All you are accomplishing is to irritate the people here on Yahoo Answers.
- 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: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:1st where is my zone valve? I have an old Burnham gas baseboard heater2nd What do I do?My last resort is calling a proffesional.
- do mean you have an area in house that the heat isnt working in? if so try by passing the thermostat zone valve is that same as circulator pump its valve in the line to radiator usually near boiler has wires onit that go to thermostat should be a circulator pump for each thermostat
