Q:All inclusive ball valve and half a bag of the difference between the ball, mainly new manual ball valve

Only know global valve and hemisphere valve, all inclusive Half pack? I don't seem to have heard of it. Discuss the problem in detail and see if you can explain it.

Q:How much pressure can the flange ball valve withstand?

How many can, each kind of pressure specification has the different material quality, the thickness request, the ball valve can also use in the high pressure class.

Q:Stainless steel ball valve, Q11F-10P, 16P, 11F, what does that mean?

The first 1 that connect the second ball, 1 straight through valve, F PTFE sealing.

Q:PPR gate valve, stop valve, dark valve, ball valve what is the difference between the gate valve and dark valve is a thing?

Not a thing, gate valve, globe valve, ball valve for the installation of dark valve, suitable for buried wall installation, I hope my answer can help you, Shanghai Rui River group Liaoning branch

Q:How does ball valve indicate?

Start with Q, such as Q41F-16P DN50Q is a ball of the code, second bit 4 is connected, third bit 1 is the structure form, the F fourth is sealing surface material is PTFE, 16 represents the pressure is 16KG, P stainless steel,,Specific refer to valve selection manual,,

Q:Daily maintenance of ball valve

Longer service life and maintenance free period will depend on several factors: normal working conditions, maintaining a consistent temperature / pressure ratio, and reasonable corrosion dataBall valve in the closed state, there is still pressure fluid inside the valve bodyRemove the line pressure before servicing and leave the valve in the open positionDisconnect the power or air supply before servicingBefore the maintenance, remove the actuating mechanism from the bracketMust be found on the ball valve, the downstream pipeline has been removable pressure, in order to disassemble, disassemble operationIt is important to be careful not to damage the sealing surfaces of the parts, especially non-metallic parts, to remove the O rings. Use special tools when taking apart and re assemblingWhen assembling, the bolts on the flange must be symmetrical and tightened gradually and evenlyThe cleaning agent should be compatible with rubber, plastic, metal parts and working medium (such as gas) in the ball valve. When the working medium is gas, the metal parts can be cleaned by using gasoline (GB484-89). Non metallic parts are cleaned with pure water or alcoholThe non-metallic parts should be removed from the cleaning agent immediately after cleaning and should not be soaked for a long timeNeed to be cleaned by washing the wall after volatile cleaning agent (cleaning agent can not dip silk rub) for assembly, but not for a long time on hold, otherwise it will rust, dust pollution

Q:Is the stainless steel ball valve forged steel ball? Which one is suitable for the gas pipeline? (FAQ

Stainless steel refers to the material composition, forged steel is a molding method. Not a concept.Stainless steel can be either a casting or a forging.

Q:What is the ball valve core?

Ball valve spool is the ball, valve opening and closing parts (sphere) driven by the stem, and around the stem axis rotation. More ball material, carbon steel, forged steel, ceramics and so on.

Q:What is the maximum temperature resistance of the 304 stainless steel ball valve?

What seal do you have?.PTFE sealing maximum temperature: 120 degreesMetal seal maximum temperature: 325-400 degrees, look at the manufacturers.

Q:Hard sealing ball valve, what method can calculate the leakage? How much is grade 4? How much is grade 5? How much is level 6? For example: how many DN150 seals are 5 ml?

Generally requires V level, but for some valves, meters will purchase higher level. For engineering inspection, the bubble method is used.Valve leakage level has six levels, the highest level six, is often called a zero leakage.
