Please consult customer service before placing an order( in order to confirm with size and material of the relevant product).
- Q: What is the service valve?
- In front of the valve will need to be all pass, that is, the hole and the ball valve line diameter consistent, the ball will not be card.
- Q: Who knows why the ball valve is divided into a piece of ball valve, two pieces of ball valve, three pieces of ball
- There is, of course, a difference,This is according to the structure of the valve body,The difference between them is whether they are easy to disassemble, for example, the three piece of ball valve is easiest to disassemble.
- Q: The hot water pipe ball valve what brand alone?
- Such as the bathroom taps are generally alternating hot and cold water, will be pulled out from the faucet two hoses, and then connected to the wall, embedded in the wall of the interface is angle valve. Because the heating pipe at the corner of the shape of 90 degrees angle, and the ball valve is straight through, so the basic difference between angle valve and spherical valve is that the angle valve exports and imports into 90 degrees right angle. rn usually angle valve mainly plays four roles: rn transfer within rn out nozzle; when the water pressure is too large, can be adjusted in the triangle valve above, turn down; the rn with switch function, if the leading Water Leakage phenomenon, can promptly put the triangle valve off, instead of the total valve closed in the home.
- Q: Can the check valve replace the ball valve?
- No, but the ball valve can not replace the check valve!Ball valve is artificially to switch, the need for external force, there will be the operation is not in time, the action is not rapid, and other ills.The check valve is automatically opened and closed by hydraulic differential pressure, and the action is accurate.
- Q: PPR ball valve diameter is 3 cm, what is the specifications?
- The PPR32 ball valve with the DN25 is a specification. (DN25 is the nominal diameter of the pipe and PPR32 is the outer diameter of the pipe)The PPR25 ball valve with the DN20 is a specification.
- Q: Advantages of track ball valves
- 10, the valve refractory design, API, 6FA and API 607 standards. All valves are fire resistant and safe.The valve seat sealing surface., all metal seal structure, when the fire, still can guarantee the sealing medium leakage, stop.The flange. In stainless steel and graphite gasket, can meet the requirements of fire;The stuffing box is arranged. Flexible graphite packing, can lose the effect due to fire and other reasons in other packing flexible graphite packing to seal effect can meet the requirements of fire;11, the valve stem through the stem nut, valve cover, valve body, between the core of the ball formed a continuous circuit conduction, to achieve anti-static effect.12, in order to improve the reliability of the valve, safety and sealing capacity, to reduce the failure rate, the valve low-pressure air tightness does not depend on the seat spring to achieve.13, the stem and valve ball position by stem guide pin and stem to cut off the coordination to control, in order to ensure the stability of valve operation, stem guide pin for double guide pin, and stem guide pin can be removed and replaced from the outside.14, hand wheel or bearing fixed, use bolt or nut compression, do not use elastic clasp.15, the valve installation size and the existing valve consistent, with good interchangeability.
- Q: Difference between fireproof and antistatic ball valve and ordinary ball valve
- Ha ha, that is, non sparking metal, alloy, copper, alloy, aluminum is all right
- 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: For example, how many sizes and pressures are used in the two piece?
- First of all, the difference between a ball valve and two chip, three chip ball valve is a ball valve flow, the internal structure of the necking design belongs to the design, the same diameter ball valve products must be smaller than the other two kinds of ball valves flow more. Compression capacity is not as good as two, but better than the three chip. A ball valve has the advantages of low cost, low price; the two valve is the three products in the most excellent in resistance and flow, the valve inside is preferred; features three ball valve design structure is easy to install, because the three ball valve can be installed by dismantling during installation, so in different pipeline even some other connections are completely no problem, fast loading, thread, flange, welding and so on, so the market is the most complete connection number of ball valve, especially when welding, a chip ball valve and the two valve can not be opened due to installation, want to welding in the pipeline it would be easy to the inside of the PTFE (similar to plastic) in a burnt out, the best choice at this time is three piece ball valve. But the disadvantage of three piece ball valve is the poor compression ability.
- Q: How to distinguish between single and double ball valve?
- I don't know what you mean by "single" and "double", but the ball valve can be divided into one, two and three.
