Q:Why anti condensation of aluminum alloy anti condensation butterfly valve?
Anti condensation butterfly valve multi-level unique progressive contact seat design, the valve plate in close contact in the process of gradually seat, ensure good sealing performance while reducing unnecessary torque, and the butterfly plate of stainless steel and the inner parts, thereby prolonging the service life of the valve seat, has strong rust and corrosion function. Torque reduction enables the drive to be lightweight and miniaturized. Unique stem seal prevents fluid leakage.
Q:What do you mean, handle, butterfly valve, hard back and soft back?
The butterfly valve of the handle butterfly valve is installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is between 0 degrees -90 degrees, when rotates to 90 degrees, the valve is fully open. This valve is mounted horizontally.Butterfly valve has an elastic seal and metal seal two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.The hard back is the metal seal, and the soft back is the elastic seal.
Q:How to control the single acting pneumatic butterfly valve?
There are single acting pneumatic head, we must pay attention to often open or normally closed, we must pay attention to.
Q:Butterfly valve sealing material has several?
Nine: X1 (natural food gum), X2 (Heipalen), X3 (ethylene propylene rubber), X4 (neoprene), X5 (Ding Qing X6 (rubber), wear-resistant rubber (FPM), X7), X8 (silicon rubber), X9 (heat resistant ethylene propylene rubber)
Q:Is a valve adjustment necessary on my vulcan 500 motorcycle?
In reality, lots of bikes go their entire lives without a valve adjustment. In my opinion that is a great way to ruin a bike though. They have a maintence schedule for a reason. If a valve isn't seating, it can hurt performance and the valve will not be able to transfer heat to the head. That can burn a valve and cause detonation. You have to check valves to adjust them, and the labor for just checking will be nearly the same or identical to doing the adjustments. I do all my own wrenching, so money isn't really an issue, but if I were you, I would just bite the bullet and take it in.
Q:What does the butterfly valve D361H - 25C DN350 mean?
Corrigendum: correct type: D361H-25 DN350Should not have C, nominal pressure above 1.6MP carbon steel valve material code name should be omittedValve: central vertical plate welded turbine butterfly valve, nominal pressure 25kg, caliber 350mm, body material, carbon steel, sealing surface material: Cr13 stainless steel

Q:Old Thompson Aircraft Engine Valve, help dating?
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
