FAQ

Which one is more durable?

Where can I distinguish it from the handle?!!In simple terms, the heavy ones need to wear a little longer

O ball as general regulation of opening extent

Hard seal can be adjusted, soft sealed, please be careful.The opening 0~90 curve is getting faster and faster

It's the brass valve in front of the water meter. It doesn't move at all. It's broken. Found the following axis of rotation is not rust, copper plated iron, with a screwdriver to the ball screw, screw is not moving, the valve is much worse than PPR. Real junk products

That's the valve stem. It didn't eat in the slot. The product was useless. Buy a new one

The valve nominal 1/2, 3/4 is how much?

Nominal diameter 1/2 3/4 corresponding to DN15 DN20

What is the meaning of ball valve model Q947MF-2.5C?

Q stands for ball valves, 9 for electric installations, 4 for flange connections, 7 for straight through runners, 2.5 for 2.5 kg pressure, and C for carbon steel for valve bodies,

I design water meter transformation, 50WPD table, the original table before the installation of 50 anti-theft valve, table after the installation of 50 of the globe valve; master let me put anti-theft valve into anti-theft gate valve. Switch the stop valve to the gate valve. I'd like to ask what kind of valve is appropriate Why? And I checked from the Internet that the ball valve is generally used for small aperture, this aperture range is how much? Why?No copy paste, thank you......

First, the advantages and disadvantages of the ball valve1, advantages:Minimum flow resistance (actual 0);Because it is not stuck at work (without lubricant), it can be reliably applied to corrosive media and low boiling liquid;Complete sealing can be achieved in larger pressure and temperature range;It can realize quick opening and closing, and the opening and closing time of some structures is only 0.05~0.1s, so that it can be used in the automation system of the test stand. Quick opening and closing valve, operation without shock;The spherical closure can be automatically positioned at the boundary position;The working medium in the two-sided reliable seal;In the fully open and fully closed, the ball and seat sealing surface and the dielectric isolation, the high-speed media through the valve sealing surface will not cause erosion;It has the advantages of compact structure, light weight, it could be considered for most reasonable structure of the valve system of medium low temperature;To body symmetry, especially the welded body structure, can well withstand the stress from the pipe;The closure of parts can withstand the pressure differential.11;They all welded ball valve can be buried underground, so that the valve parts from erosion, the maximum life of up to 30 years, is the most ideal oil and natural gas pipeline valve.

What is the difference between PPR ball valve and PPR live ball valve?

PPR and PPR union ball valve is different: PPR union ball valves and pipes on both sides (hot melt) connected between, a movable joint (hot melt) and (link with) nut, maintenance, convenient disassembly and replacement of the valve, the union not only cut off the PPR ball, maintenance.

The toilet water pipe valve is broken, with a new twist, how are the screw does not move, then they told me to go on to the pipe on the water and then tighten, did as he said, really screwed, but do not know why, please tell the master what is the principle, if it is water without water when the screw does not move, but when the water can twist. What a kink!Is the water valve normal, a pull rod, pulling it back flush, do not rush the kind, the middle is a hollow ball

I think it should be the water holding gas, connecting device principle, at the bottom of the hand, barometric pressure, and the best you can last map, I'll see
