Q:Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?

Hard seal butterfly valve in any case, the reverse loading will cause tight seal.

Q:DN80 flange butterfly valve, DN80 flange butterfly valve DN80, flange butterfly valve DN80 what is the difference?

No, what's the difference?. It's not all the same.Flange connectionDN80 caliber butterfly valve. What's the difference?. Model and pressure. Materials are not ~!

Q:Which is more expensive, gate valve or butterfly valve?

Same diameter, the same material, with the pressure level, the weight of the gate valve is much heavier than the butterfly valve, about 2 times of the butterfly valve!

Q:How can the flange butterfly valve be installed on the pipe?

It is better to install it vertically or horizontally, and leave some space for maintenance

Q:How much is the Honeywell butterfly DN300?

Find the agent or find a reliable valve plant a lot of foreign brands are in Chinese OEM so find a reliable factory is relatively good service to keep up

Q:That industry uses most of the butterfly valve, and only use the butterfly valve, a large number of use of butterfly valve, seek expert advice!

See what kind of butterfly valve: 1., the use of all metal, mainly in the chemical industry.2. large diameter butterfly valve, mainly in low pressure water pipes and wind pipes3 environmental protection water treatment factory with more butterfly valve.

Q:I got my timing belt done on a 1999 Civic Si on September 26 @ 113,699 miles. at 116,9xx miles I bent a valve on my third cylinder. How likely is it that the timing belt is the reason why this happened? I heard that if the timing belt is a tooth or so off, it could bend a valve. So is it likely that this could have happened? Anyway to check?

A TDI has no valve to piston clearance as a results of the indisputable fact that's a diesel and has a extreme compression ratio. i'm a mechanic myself and hate to slam different techs yet it truly is clearly a screw-up on his section. There are some issues that would have exceeded off even if the shop he works at is to blame for the damages. If the tensioner did bend (which I surprisingly doubt exceeded off) then he has recourse by the business business enterprise that man made the tensioner yet to be quite truthful, it truly is only no longer real. similar is going for the snatch problem. that only isn't plausible. good success.

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:Transformer butterfly valve and pressure relief valve difference

The oil immersed transformer pressure release valve is a safety device installed in the transformer, when the internal pressure is less than the limit value of the transformer such as 35kPa, which is in closed state, when the transformer internal fault occurs, a large number of transformer oil by pyrolysis, produce large amounts of gas, the internal pressure of the oil tank increased dramatically when the opening pressure exceeds the pressure release valve when the pressure relief valve opens, the internal oil and gas overflow, to release the pressure, avoid the pressure on the inside of the lead tank cracking or permanent deformation, when the fault of transformer internal end, internal pressure tank to reduce pressure release valve closing pressure, it will automatically shut down to prevent outside air enter the inside of the tank or water.

Q:What is the effect of nylon coating on butterfly valve plate? Thank you

Mainly media will not be contaminated by rust on the body, you should say that the central soft sealing butterfly valve, the central valve is generally cast steel or cast iron material, so useNylon coatingLining up. There are soft seals, sealing performance is relatively high
