Q: How many kinds of ball valves are there?: Ball valves (ball valve in the field of marine engineering and ships should be cut-off valve), standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the axis of the ball valve to rotate the valve movement.".

Q: Is the stainless steel ball valve forged steel ball? Which one is suitable for the gas pipeline? (FAQ: This does not mean cast steel can not be used. Cast steel is also acceptable because all the check valves and control valves of natural gas lines are cast. But the casting process has a high probability of defects.

Q: And the cut-off valve is not the general name of gate valve and butterfly valve?What are the signs of differentiation?How about the use?: When the valve is opened, the opening height of the valve is 25% to 30% of the nominal diameter, the flow has reached the maximum, which means that the valve has reached full open position, so the opening position of the stop valve should be determined by the stroke of the discThe cut-off valve has the following advantages:The utility model has the advantages of simple structure and convenient manufacture and maintenanceSmall travel time, short opening and closing timeGood sealing, friction between the sealing surface of small, long lifeThe disadvantages of the cut-off valve are as follows:The resistance of fluid is large, and the force required for opening and closing is largerNot suitable for medium with particle, viscosity and easy cokingPoor regulation performanceType valve stem according to the position of divided threaded screw type, internal thread. Divided by the flow of media, there are straight through, DC type and angle type. Divided by the form of valve seal, a packing seal bellows seal valves and valve.The installation and maintenance of the cut-off valve shall pay attention to the following matters:The stop valve operated by the handwheel and handle can be installed in any position of the pipeHand wheel, handle and steering mechanism are not allowed to be used for liftingThe flow direction of the medium shall be in accordance with the arrow shown in the valve body

Q: PPR gate valve, stop valve, dark valve, ball valve what is the difference between the gate valve and dark valve is a thing?: Gate valve in general, over the water, the cut-off valve is generally in the air, the ball valve over the water will do, the valve is divided into open bar gate valve, dark rod gate valve, you say the dark valve should be dark rod gate valve

Q: Allowable leakage on ball valves: what does CLassVI mean?: This is the valve leakage level, level VIThe GB/T4213-92 standard specifies six grades for the valve leakage. The specific requirements are shown in the standard table. The lowest level is level I, without specific requirements; the highest level is grade VI, i.e., the bubble grade.

Q: The valve nominal 1/2, 3/4 is how much?: 1/2 equivalent to the national standard of 15mm, 3/4 equivalent to GB 20mm. That is, DN15 and DN20

Q: Is the ball valve switch in front of the water meter or after the water meter?: the owners of their own decoration or repair, in front of the water meter is generally C type locking valve or valve, if less water, property control, no special key you open

Q: Ball valve Q41f and Q11f difference, whether universal?: Generic. The Q41F 4 stands for flanged connections, and the Q11F 1 represents the internally ribbed pipe

Q: What is the difference between gas ball valve RQ11F-25P and ordinary stainless steel spike valve Q11F-25P?: The models are all the same. What's the difference? Q ball valve, 1 internal thread, 1 floating through type, F PTFE sealing, 25=2.5mpa, P stainless steel.

Q: I've seen a lot of hot water projects. Why do most of them use globe valves, and ball valves are seldom used?.Globe valves have those benefits compared to ball valves (because the cut-off valve is more expensive, I think it is more expensive and more useful. It must have some advantages in that respect.)Is the stop valve more durable than the ball valve?What are the specific differences between the two PPR valves?: The PPR valve is plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. Stem movement in the form of lifting rod (stem lifting, hand wheel not lifting), but also lifting, rotating rod type (hand wheel with the valve stem to rotate up and down, nut on the valve body). Valve is only applicable to fully open and fully closed, does not allow for adjustment and throttle.Ball valve has compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide methane and ethylene, etc., are widely used in various industries. Ball valve body can be integrated, or can be combination.
