Q: Why anti condensation of aluminum alloy anti condensation butterfly valve?
Anti condensation butterfly valve principle: the use of the high performance plate material, can effectively prevent the temperature of body parts, isolating the transfer medium in the pipeline, to the actuator and the connecting flange surface without dew.
Q: Import electric butterfly valve which brand is more reliable?
Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.
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: Not the cold and hot water shut off valves. The one with a tiny handle and it looks like a T. what does it do? should I mess with it?
It maybe the valve for your Ice maker / refrigerator or it maybe for the dishwasher. You should be able to look and see where the pipes go. If there is no pipe connected to the valve then it may be there in case you want to install an ice maker or dishwasher. Don't mess with it unless you know what you are doing. Valves like that can start to leak if you go messing with them. Especially if the valves are old.

Q: I went online to check where was the pcv valve for a 2001 ford focus, but I didn't find it. Does anyone have a picture? Thanks
The PCV (positive crankcase valve) is usually on top of the engine or in the valve cover, but it will be in different locations depending on the engine cylinder count: 4, 6, or 8 cylinder. You may have to go to a dealer and ask for a parts breakdown drawing which will show you where all the various parts are located. Some libraries have big books that show all the details about any model of car. Ask around.
Q: What are the butterfly valves models?
Sealing surface material score:(1) soft sealing butterfly valve.1) the sealing pairs are made of non-metallic soft materials, which are made of non-metallic soft materials.2) the sealing pair is made of metal hard material and is made of non-metallic soft material.(2) metal hard sealing butterfly valve. The sealing pair is made of metal hard material and is made of metal hard material.According to the form of sealing:(1) forced sealing butterfly valve.1) elastic sealing butterfly valve. The pressure of the valve seat, seat, or plate is produced when the seal is closed by the pressure from the valve.2) additional torque seal butterfly valve. The seal is produced by a torque that is applied to the valve shaft.(2) pressure sealed butterfly valve. The pressure is greater than the pressure on the seat or plate.(3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium.
Q: I have a good set of #142 Pontiac heads with small diameter valves. I want to have the heads enlarged to accept the larger Pontiac valves, and I have the larger exhaust valves out of #13 heads and the larger intakes from 6X8 heads. The valves appear ok and shiny on the stems
Roll the valves by the stems on a perfectly flat table. If there is no wobble, your valves are most likely not bent. Take them to a machine shop and have them checked for imperfections and reground and they'll be good as new.
