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: My caravan is a bit sluggish on the pick up, I replaced the wires/plugs and the electronic distributor(I think thats what it is..). still a bit sluggish. Should i look at the valve gasket? Or fuel filter, or fuel pump next? 03 caravan sport 3.3L
the valve pan gasket won,t cause it but the fuel filter will if it,s starting to clog up and also the cat nverter !
Q: What does "10" in the butterfly valve "D71X-10" mean?
The pressure of 10 kg 1.0MPA is usually cast iron
Q: What is the electric butterfly valve? Please, great God!
ZSDF type fire signal butterfly valve uses: top of the ZSDF type fire signal butterfly valve with the valve opening and closing signal device, when the valve is closed by 25% (open degree 4/1), the signal device output signal was mistakenly closed to the fire control center.
Q: Fire, the signal butterfly valve flange connection or welding?
Grooved flange joint, welded flange connection! Wire bonding. Wire to flange connection! In addition, you can choose the groove type signal butterfly valve!
Q: What are the butterfly valves models?
Divided by way of drive(1) electric butterfly valve(2) pneumatic butterfly valve;(3) hydraulic butterfly valve;(4) manual butterfly valve;In the form of structure:(1) Central sealed butterfly valve(2) single eccentric sealed butterfly valve(3) double eccentric sealed butterfly valve(4) three eccentric sealed butterfly valve;
Q: I was wondering if someone could tell me the manufacturing date on this aircraft engine valve.
Wow Hannah! That's a cool find for sure! It appears to be possibly a valve for a radial aircraft engine as it looks very similar to ones i've seen used in Pratt+Whitney R3350's etc. It looks like it could probably date to the 1940's up thru the 1950's. Look for a Part Number stamped on the valve or on the box. After WW2 there were all kinds of manufacturers making parts for airplanes. Many were gobbled up by competitors, converted to manufacturing other products or went out of business altogether. However, a few did hang on....and I think this may be what has become of Thompson Aircraft today.... Thompson Aerospace, Inc 22431 Antonio Parkway B160-102 Rcho Sta Marg, CA 92688-2804
Q: Butterfly valve network and ordinary butterfly what is the difference?
Butterfly valve used in the network structure, closed with the more closed, the more tight function, reliable sealing performance, after opening and closing, make sure that the cover is completely out of touch, to ensure that the sealing surface is not damaged. The sealing surface is made of stainless steel, corrosion resistant, high temperature resistant, long service life. With two-way sealing function, medium flow is not affected by the installation restrictions (if only one-way control medium should be used to seal the installation direction) is not affected by the spatial units, can be installed in any direction.
Q: What are the uses and classifications of manually operated clip butterfly valves?
Manual to clip butterfly valve use: manual to clip butterfly valve butterfly plate installed in the pipe diameter direction.
Q: Buried extension butterfly valve is buried or need to repair the valve well, can build the valve well, the extension rod butterfly valve installed in the valve well, the extension rod to avoid covers, the top of the valve well out, so that the hand wheel in the ground operation.Atlas S143 is less than the inner diameter of DN150 valve wells only 1200mm, DN200-DN250D diameter of only 1400mm, 700mm valve covers, valve rod and a handwheel to lengthen through the valve cover, valve wells is built to cover the embedded pipe or tube? Is there a standard atlas?
Hand wheel operation in the ground, the original operation on the ground, our company's extension rod is in accordance with the length specified by the manufacturer.
Q: What's the meaning of butterfly valve d371po?
According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve3== transmission: worm gear7== connection mode: clip type1== structure: midlinePo== sealing surface material: lining PoPo== propylene oxide (PO)
