Q: What does "DN25 Q41F46-16C" mean?: DN is nominal diameter, nominal diameter (or nominal diameter), that is, all kinds of pipe and pipe accessories of general diameter of 25 mm

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.

Q: What do you mean by ball valves dn20pn1.6rf?: DN20 caliber is 20mmPN is the pressure grade, usually PN16, 1.6MPa classRF convex flange connectionYour side should be similar to the Q41F-16 model of this type of ball valve

Q: Are ball valves and float valves a thing? If not, what valves belong to the valve, screw valve, threaded flange valve, welding flange valve or flange valve?.Online, etc.. Thank you: The answer upstairs is more accurate, I will add.1. ball valve: refers to the valve spool (seal components) for the ball shaped valve, collectively known as ball valves.2. float valve, that is upstairs to explain the kind of specific, you can refer to the toilet, which is used on the water supply device is this structure.The 3 threaded valve, threaded flange valve, valve flange welding flange or valve: This refers to the connection forms of body, such as your home with the water valve between the valve and pipeline is usually a threaded connection, then the other is threaded, welding, flange connection means.

Q: What does "ball Q41F-16" mean?: Q- ball, 4- flange connection, 1- DC channel, floating ball, F- sealing material for fluorine plastic, 16- nominal pressure of 16 kg, the valve body material for gray cast iron. If you want to know the details of the valve named model establishment, can refer to the JBT-308-2004 standard.

Q: What is the principle of forced sealing ball valve? How to achieve mandatory sealing function? Is it suitable for high pressure conditions?: Structural characteristicsForced sealing ball valve combines the advantages of ball valve, gate valve and plug valve. It has the characteristics of good tightness, no wear and tear, erosion resistance, and on-line maintenance.(1) the bevel of the lower end of the forced seal lift stem provides a mechanical wedge tightening force to ensure continuous tight seal.(2) switch no wear, valve switching process, the ball deviates from the valve seat and then rotating, eliminating the friction of the valve seat, to solve the ordinary ball valve, gate valve and plug valve seat wear.(3) the anti erosion lifting stem realizes the rotation of the ball from the valve seat, and the ball and the valve seat perform the switching action without contact. When the valve is open and about to be closed, the fluid flows immediately along the sealing surface in the range of 360 degrees. When the fluid begins to flow, it can flush the impurities on the valve seat. To avoid the high speed fluid in common ball valve opening and closing the micro moments of local scour on the seat, even the harsh conditions of high pressure, can still ensure long-term zero leakage and tight sealing, improve the service life of the forced sealing ball valve.(4) no case single seat design avoids the valve cavity pressure increases and easy to jam problem.(5) good sealing performance, the ball and valve seat sealing surface after special hardening treatment, can not damage the integrity of the seal to meet the very harsh conditions of sealing requirements.(6) easy maintenance valve adopts top mounted structure. After decompression, it can be checked and maintained online, and the maintenance is simplified.

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: The valve nominal 1/2, 3/4 is how much?: Nominal diameter 1/2 3/4 corresponding to DN15 DN20

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.

Our company is specialized in the production of a series of products, such as knife style gate valves, various types of metal hard sealed ball valves, PTFE soft sealed ball valves, high temperature and pressure wrought steel ball valves, eccentric semi-spherical valves and three way valves (T-pattern, Y-pattern and L-pattern), which are designed and manufactured according to international standards, like GB, ANSI/API, JIS and DIN. The main body materials of valves are LCB and LF.
