Product Description:

1. Manual Wafer Butterfly Valve Description:
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.
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.

2.Main Features of the Manual Wafer Butterfly Valve
a)Cast hole. Flange connection meet ANSI 125/150#   DIN PN10/16   BS4504 PN10/16 in the meanwhile.
b)Soft seat. Replaceable. Increase of service life.
c)Double half shaft without pin.
d) Square and short neck. Easy to stick scutcheon and cost saving.
e).Simple and compact construction. Small in size and light in weight. Easy transportation, installation and maintenance.
f).Quick 90 degrees on-off operation. Minimized operating torque ,energy saving.
g). Excellent sealing performance with no leakage. Long service life.
h). Wide selection of materials ,applicable for various media..
i). Flow curve tending to straight line. Excellent regulation performance.

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 there a leak around my home's outside shutoff valve?
i don,t understand your Question.

Q:Valve adjustment on my 1994 Honda civic ex?
Don't bother if you really don't need it (or don't know what it does). As cars get old, parts wear out and need to be adjusted. The valves open and close to let fuel in and exhaust gas out. unless you are suffering from some problem you don't need it. ==== I have 1994 Civic EX also. The good news is that the valves are very easy to access so the labor is cheap (no new parts unless the valves are really worn. good Luck P.S. My 94 Civic still runs like new and get great MPG. So if you get good MPG and have decent power, you don't need valve adjustment.
Q:Wall Heater question? (Gas Valve)?
Depends on what kind of wall heater. FOR A 24 volt system : you will need a ohm/volt meter to do that. Make sure the thermostat is calling for heat, and the gas going to the unit is on. you should have 24 volts at the gas valve. if there is 24 volts there, and the burners are not on, then the gas valve is bad. If you don't have 24 volts there, then your thermostat could be bad, and not turning on the gas valve, or you might not have control voltage. You should be familiar with basic electricity to do this.
Q:Kitchen valve stem seems to be stripped?
pull off the handle and try and turn it with channel locks or pliers, and remove the aerator screen and clean it. its very common for them to get plugged up after you turn off the shutoff valves and reopen.
Q:Bicuspid Aortic Valve-- Anyone eles have one?
Yes okorder.com/
Q:Tire valve problem?
by the time you drive around find a valve stem tool and then find a new valve core which you need to replace because it is leaking and how many times in your life time will you ever need this tool again you would be better off going to walmart tire center and have them install a new valve stem it comes with the new core and cap in 1 unit assembly
Q:After a bout with bacterial endocarditis, scar tissue often stiffens the edges of the heart valves.?
If the heart valves are damaged, they may leak, causing regurgitation of blood. For example, if the mitral valve (between the left atrium and left ventricle) leaks, blood will leak back into the left atrium when the ventricle contracts. This reduces the efficiency of the heart contraction. Regurgitation is easily detected by echocardiography. On routine physical exam it may be detected *if* there is enough leakage/ flow abnormality to cause an audible sound, or murmur, that your physician can hear with his/her stethoscope.
Q:What air pressure valve do I use for vacuum chamber?
Any valve rated WOG (water, oil, gas) is OK for vacuum. Maximum vacuum pressure differential is atmospheric pressure (14.7psi, 101.3kPa, 1 bar). For convenience, you might use a barbed valve which is sized for tubing (See Yahoo! Images: barbed conical gas valve). Any plumbing and heating supply, or commercial cooking equipment supply will have a variety of miniature bronze gas valves to choose from.
Q:Will my Hunter SVC VALVE will work with my Lawn Genie Valve?
Something is incorrect. All valve solenoids and all timers are designed to work at 24 v DC It should make no difference which brand of clock or which brand of valve you are using. Now the actual solenoid which is the circular cylinder with the wires coming out of it that screws into the valve may not fit all brands of valves but you can buy the correct brand to fit your valve at any irrigation supplier. If your controller is working with at least one valve it should work with any valve you have installed. I would look at the wiring and see that they are correctly installed and connected especially at the valve. If one of the two wires is loose or connected wrong then you wont get the valve to operate. If you have a voltage meter I would test it with that. If not make sure at least one wire from each valve is connected to the white (or nuetral wire) out of the controller and the other valve wire is connected to one of the hot wires coming out of the controller. If one valve does not work try connecting a hot wire off a working valve to the non working valve and test it. If it works your problem is in the wire you disconnected. I constantly work on sprinkler systems and wiring is no. one problem. Incidently I cant find a SVC valve listed in the Hunter catalog did you get the letters mixed up?
