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:Our factory has some ball valves in the direction of movement and normal ball valve is the opposite direction
Ball valve is 90 degrees switch, you may put the handle of the wrong position, change 90 degrees, try it
Q:What is the difference between ball valve Q41F-16C and Q41F-16P?
Ball valve Q41F-16CQ valve (Qiu represents the first letter of the alphabet), 4 representatives of 1 representative is flanged ball valve floating ball (ball valve floating ball and fixed ball, 7 ball, F fixed on behalf of) on behalf of PTFE- PTFE seal (PTFE PTFE), representing 16 of the nominal pressure valve is 16 kg (1.6Mpa). C ball valve is made of cast steel.Ball valve Q41F-16C is a soft sealed cast steel flanged ball valve
Q:How can a steel ball in a steel ball valve be put in?
This kind of ball valve usually has an external direction of compression, an arrow. Usually, the ball is filled from the direction of the arrow tail and inserted or tightened into the circlip.
Q:Q41F-16-64P this is the ball valve, what type, please answer in detail, thank you!
Q--- ball valve4---- flange connection1----- ball valve is floating ball (ball valve has floating ball and fixed ball points, 7 represents the fixed ball)F----PTFE- PTFE seal (PTFE PTFE),16-64---- ball valve nominal pressure is 16-64 kg (1.6-6.4Mpa)P---- ball valve body material is 304 stainless steel
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:Daily maintenance and common maintenance of ball valves, Q347F-16C and Q41F-16C
Filler and sealing materials pay attention to point, basically no technical things
Q:DN15 stainless steel ball valve 304 can withstand much pressure?
There is no pressure rating PN (nominal pressure) in the description, so it is not sure how much pressure it can bear.PN, nominal pressure (Nominal, Pressure) is a means of pressure, mainly used in piping and pipe fittings, valves and other shell device pressure expressed;Nominal pressure PN is a digital indication of pressure related signs, which is a convenient round integer for reference.
Q:Is a plastic ball valve, connecting France is hot melt.
The development of industrial products is closely related to technology, quality and market. Technology is hard, but the quality of winning products, users can be recognized? Can you pull the market share? Definitely not. I do heating, for all kinds of valves are not unfamiliar, especially domestic on-off type heat meter, more use of electromagnetic valves, mostly belong to ball valve.
Q:Check valve, ball valve, check valve are used in what place, ah?
This problem may have two meanings: first, what are these pipe fittings used in? Two, globe valve, ball valve, check valve, their respective uses and occasions. First of all, these fittings are used in pipework, i.e., where gases, liquids, or gases are used as power sources. Therefore, almost all industries (Engineering) are required to use, especially chemical enterprises, water supply, hydraulic systems are more widely used.Pipe (valve) the most important parameters are the use of pressure, pipe nominal diameter, the use of medium, temperature, spool valve body material. Many types of valves, the most common are cut-off valve, gate valve, ball valve...... , check valve (many forms) is to prevent fluid back, such as the need to install the pump outlet, the pump stops to prevent fluid back, therefore, the fluid requirements in the process are not allowed back to places which need to install a check valve. Cut-off valve is mainly used for the need to cut off the fluid, it is good tightness (not easy to leak), but the resistance is greater. And the ball valve, its spool is a ball shaped body, simple structure, convenient switching, but its adjustment and pressure resistance is poor, so often used in the smaller diameter of the water pipe. For further information, please refer to the valve selection manual. If required, please provide the QQ mailbox for your electronic books.
