FAQ

Here, the original water leakage, has not been closed, recently closed for other places, twisted two times, and now it is so,Ball valve leakage of this place, how do? Here, the original water leakage, has not been closed, recently closed for other places, twisted two times, and now it is the case, how can I ask?
The seal on the valve body is broken. Screw it down and change the gasket
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.
The working principle of the track type ball valve
With its unique structure, the spool rotation separation open, new technology design of mechanical seal pressure, is the most prominent advantages of the sealing surface does not produce friction, long service life, low operation torque, even if the medium water content of solid particles, sediment, short fiber and other impurities, high concentration fluid flushing sealing condition of body harsh, can maintain good sealing, to ensure the engineering equipment maintenance period in the safe and reliable operation.
Is the water inlet valve good or the ball valve well?
The ball is good, recommended to install copper ball valve, not easily broken, rust resistant.It's not a bit of space to install valves at home. Moreover, the valve height is relatively high, the ball valve is that the handle occupies only the place, the handle to go, than the gate does not know how much space.We are specializing in the sale and installation of plumbing valves, and give you a professional answer.
DN15 ball valve with a bit of outer wire
We normally say 4 points, 6 points, 1 inches, corresponding to 152025
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.
To help explain the meaning of the ball valve Q11H-16H, combined with the actual, such valves have wood?
JB T308-2004 valve model preparation method and "GB1048-2005 pipe element nominal pressure definition and selection", there are various types of valve interpretation:Q11H-16HQ: valve type: (Q) ball valve1: connection form: (1) internal thread1: structure form: (1) through flow channelH: sealing surface or lining material: (H) Cr13 stainless steel16: pressure code: (16) 1.6MPaH: body material: (H) Cr13 stainless steel
DN20 copper ball valve with large PPR converter connector
What do you see a ball valve, PPR ball valve, ball valve with internal screw threads, ball valves, but if you look at the butt of the ball size, if the ball is 20. The tube is 20, then the 20*1/2 internal thread can be directly on the butt.
