Features
The butterfly valve has the ideal sealing track since following three-eccentric principle, without friction and interference between sealing seats, and also adopts the proper material, which make the butterfly valve have the reliable sealing ability, corrosion resistant, temperature resistant and wearing resistant. The main features as bellow:
1.Small open torque, flexible and convenient, laboursaving and energy economised.
2.Three-eccentric structure to make the disc more and more tighter, with reliable sealing ability and no leakage.
3.High Pressure resistant, corrosion resistant, wearing resistant, long lifetime.

- Q: How can one - way sealed butterfly valves and two-way sealed butterfly valves be distinguished?
- The difference between one way butterfly valve and two way butterfly valve:One way hard sealing butterfly valve:The butterfly's body usually has an arrow to indicate the direction of media flow, the butterfly valve plate in front of the closed, must face the flow of media, so we should pay attention to the medium flow direction when installing a one-way valve.
- Q: What is the meaning of the D341*5-10 / 16ZB1 turbine butterfly valve flange said?
- Liu1964tg, this guy is right, don't know, don't mislead everybody
- Q: What's the material of the butterfly valve seat?
- The seating material shall meet the following criteria:1) fluid compatibility, including expansion, hardness loss, permeability, and degradation;2) hardness;3) permanent deformation;4) the degree of recovery after load removal;5) pull in and compressive strength;6) deformation before fracture;7) modulus of elasticity.
- Q: I have 1993 Seville 4.9. I got a new EGR valve but it didn't help. I tested it with vacuum pump, it won't hold pressure at all, same with old one. Is that new EGR valve bad or just different type of EGR that vacuum pump won't work? Thanks!
- HI i have question is all EGR valve work the same ? I Have an 86 Rx7 and when I test the EGR valve is doesn t hold pressure. So I m curios are they different from other vehicle due to is a rotary engine or due they all work the same. Thank You.
- Q: What's the difference between turbine butterfly valve and manual butterfly valve?
- The turbine can light and close the valve here. It is more labor-saving and reliable. It is closed and open. Manual operation is relatively difficult, but the manual action is very fast. Fast switching. General large bore turbine.
- Q: What does the butterfly valve model d344h, d345h, d346h, d347h mean?
- According to the international standard of the letters and numbers apart to explain D344H D is a unit of butterfly valve, two unit 3 is driving mode: turbine, three unit 4 connection: flange connection, four unit 4 Structure: seal type linkage, five unit H sealing material: Cr13 stainless steelD345H compare yourself to the above. Unit 5 four is a sealed, single eccentric structureD346H four unit 6 is an unsealed center vertical plateD347H four unit 7 is unsealed double eccentricIn general, there is only one difference between them: the structural form is different!
- Q: valve adjustment 2001 chev prism 1.8L
- valve adjustment . you need to know the fire order. the gage between the stem. rotators the cranshaft. it could be cold start. cylinder need to be bottomed center.
- Q: Which is expensive, butterfly valve?
- Butterfly valve is more common, less material and simple structure. Butterfly valve cheaper
- Q: I HAVE A 2003 FORD EXPEDTION THAT IS IDLE ROUGH,AND WILL EVENTUALLY STALL. TODAY I FOLLOWED THE PCV VALVE HOSE TO THE BACK OF THE THROTTLE BODY AND NOTICED THERE IS A BIG HOLE ON THE ELBOW OF THE HOSE. HOW CAN I CHANGE IT? CAN I JUST FORCE THE HOSE OUT AND SIMPLY PUT A NEW ONE? BEEN HAVING THIS ROUGH IDLE /STALL PROBLEM FOR A WHILE I CLEANED IAC VALVE, THROTTLE BODY CHANGED THE AIR FILTER AND ALSO CLEANED THE MASS AIR FLOW SENSOR, I HAVE A P0171 system to lean(bank 1) code
- So, the rubber elbow hose has a hole in it. Your best bet is to get the replacement from the Ford dealer. Yes, you can buy just the elbow part from the parts counter at the dealer. If they start acting all dumb (and won't help you or sell you the part) then, go to a different dealer for the part. Another thing you could try is a used one from the junk yard BUT, it's been my experience that the rubber gets too hard and the PCV valve needs a lot of encouragement to be removed. Sometimes you'll damage the used elbow by trying to get it off of the engine or removing the old PCV valve to put in your replacement valve. That's why I recommend getting a new one straight from the source. They are pretty simple to change with ordinary hand tools and some mechanical know-how. You just pull the elbow off of the port that it's attached to on the engine. The valve will probably have a steel clip that goes around the hose at one end of the valve inside of the hose. You simply squeeze the clip with a pair of pliers and tug at the valve until it comes out of the elbow.
- Q: What is the difference between wafer (flangeless) type and LUG type of butterfly valves?
- WAFER butterfly valve is the valve is divided into LUG (ears) with and without LUG, ordinary LUG without clip on 12 points in the direction of valve is generally two to four bolt holes was not, whereas the LUG of butterfly valve cross dispersed in a circle. Bolt hole. With LUG all bolted through the LUG, so that the butterfly valve and the clamp on the two flange connection is more solid, you check the valve picture, it is easy to understand
