1. Manual Wafer Butterfly Valve Description：
A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.
2.Main Features of the Manual Wafer Butterfly Valve
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.
6. Long service life, standing the test of tens of thousands opening/closing operations

5.FAQ
1. What is manual wafer butterfly valve?
A: Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.
2. How about the Installation of the Wafer Style Butterfly Valve?
A: Butterfly valves are installed by inserting the valve between two flanges using bolts or studs and nuts to hold it all together. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug style valve.
3. What is the working principle of manual wafer butterfly valve?
A: A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.
- Q: is it possible to check valve to piston clearance with out taking the heads off? I want to buy a bigger camshaft for my 351 windsor stock pistons with 1970 heads. cam is 230 duration (280) and 512 lift
- 289 bored to 351? Maybe possible to STROKE it to 351, but I've never heard of it. I have heard of people running that much lift with stock springs, but I wouldn't recommend it. It's easier to change the springs with the heads off, so you might as well pull them and check clearances with clay.
- Q: will adding a bypass valve onto an air filter effect gas milage or horsepower?
- bypass valves are for cars with forced induction IEturbocharger,supercharger it allows the air that would normally be expelled into the atmosphere blow off valve and instead putting it back into the intake which helps with less lag in building boost again. If your car is not turboed or supercharged then forget it.
- Q: I would like to know about the signal pneumatic valves are drivesn (PWM,PCM?) and about their bandwidth and bit rate. Where can i find info?Thanx!!
- Norgren okorder . You will be able to use the valve island configurator, view and download 2D and 3D CAD drawings and receive a list price for complete valve islands. The VM10 is suitable for packaging and textile machinery, electronics manufacturing and many additional applications.
- Q: I drive a 08 lancer and I want to add a SRI. Can I produce the blow off valve sound like a turbo?
- lololol (not at question just at other responses). NO u can't dude, a blow off valve is a pressure release system for turbos, Its purpose is to prevent compressor surge, its is a vacuum-actuated valve designed to release pressure in the intake system of a turbocharged car when the throttle is lifted or closed, any built up pressure from the impeller once the throttle is lifted the blow off valve releases the air to the atmosphere, you can buy different trumpets for a different sounds effect, engines that are have a turbo but no blow off valve have what is called a diverter valve that recycles the air pressure back into the air intake... If you mean a Fujita SRI exhaust system then it will just have a nicer deep tone, not a harsh high-pitched sound like the other rice burner exhaust systems..
- Q: I see a valve that says FNW on it with ( on, off ) but I'm not sure it's the main valve to the water supply. It does go to the water heater so I'm guessing that it's it. Does anyone know anything about the main water supply valve and how to find it?
- My water hose has a valve at the base of it close to the wall, if you need to shut off the main supply to the house it is usually located in the front yard close to the street. Mine have always been enclosed in a Cement type box that is in-ground with a lid that is flush with the ground.
- Q: 1995 Yukon need valve lash adj- how and hat tools?
- remove valve covers, watch front left two lifters and turn engine, by bolt that holds harmonic dampener to front of crankshaft, so mark on dampener lines up with mark on front cover. If rocker arms do not move as marks line up engine should be on top dead center number 1 cylinder. Now you can adjust exhaust valves 1, 3, 4, 8 and intake valves 1, 2, 5, 7 [ odd numbers are on the left bank from the front 1,3,5,7 even on the right bank from the front 2,4,6,8]. Adjust by turning nut in rocker arm out until movement is felt than tighten until all movement is gone and tighten one turn more. After done with the first eight valves turn engine over one full turn till marks line up again. Then adjust exhaust valves 2,5,6,7 and intake valves 3,4,6,8 the same way.
- Q: Do most V6's have 24 valves? What are they for? (brief description would be fine)
- V6 Dohc 24 Valve
- Q: How do you take out a valve stem?
- NO, The valve cap is only used to keep dirt and debree from going inside the valve stem. If dirt or other particles of debree go inside where the valve core is when you air up the tire the dirt could lodge between the core and then it will leak air causing the tire to go flat. To remove a tire valve core, there is a special tool that you put inside of the valve stem and then you unscrew it out. To remove a valve stem you have to brake the tire bead push down on the side where the stem is and with the special tool screw it on to the stem and pulling it out. Reason why you have to brake the bead is that you have to replace it with a new one from inside of the wheel.
- Q: Does the heater control valve anything to do with the A/C ?My heater control valve needs replacing, as it leaks when I put my truck's heat on. No heat, no leak. I have to periodically re-add Prestone every once in awhile after using the heat . I've checked the valve and it only leaks when I have my heat on, if I don't use my heat, I don't lose fluid. But now I'm wondering if I use my truck's A/C, does the heater control valve have anything to do with the radiator fluid, or just the freon? Thanks in advanceCar Mechanic in training
- What you may really want to check is if the heater core is leaking. I have never heard of a valve actually leaking. And no the AC and Heater are 2 different systems on a car. The fan that circulates the air is the same except air flows across the heater core or the air conditioning coil. AC air is usually just recirculated in the car air where heated air is usually outdoor air combined with in the car air.
- Q: So outside we have a gas grill. There is a valve to turn when you want to use it. U can only hear the gas going when u turn the burner knobs but say u left the valve open and no knobs turned at all for 5 hours is gas escaping or does it only escape when the grills knobs are turned? Thanks
- To answer your question directly, as long as the valve is open gas will continue to flow until its turned to the off position.
