Q:What is retractable hemispherical valve? What's the area with the manual hemisphere valve?: Telescopic hemisphere valve is a telescopic hemisphere valve, ordinary hand hemisphere valve, of course, without expansion joints.Telescopic ball valve is a combination of expansion joint and ball valve.

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: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: There is a ball groove, the shaft is connected with a handle is installed in the tank, due to frequent water tap connecting parts have a certain slope groove and the shaft, causing slipping the ball still turn the handle when (the metal ball). Difficult to repair, usually replace the whole ball valve.

Q:What's the difference between a one piece ball valve and a two piece ball valve?: Is the valve body is not the same. Look for a map and see

Q:Difference between fireproof and antistatic ball valve and ordinary ball valve: Fire valve is generally aimed at soft sealing material valve, that is, after the fire on the valve, the ball valve can rely on medium force and metal valve seat (body) contact, to achieve sealing, so that the fire does not go down the pipeline. Anti-static valve is for soft sealing material of the valve, when the ball switch and soft seal friction, will produce static electricity, if the pipe is taking the flammable and explosive medium is very dangerous, so the valve will set a device outside the sphere will Unicom electrostatic oriented, to prevent static electricity.Generally like the market valve, a little better quality, they are the default valve is fire, anti-static, the production costs of these two types of valves is bad, at most two or three dollars, which is still much.

Q: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,

Q:Pneumatic two stage ball valve principle: Two section type pneumatic ball valve, pneumatic piston two stage shut-off valve to achieve a two step or two step off the action of the cut-off valve is a special pneumatic valve, provides 0 degrees, 45 degrees, 90 degrees or 0 degrees, 90 degrees, three operating mode 180 degrees.

Q:Is the ball valve switch in front of the water meter or after the water meter?: The specification, both before and after the water meter valve; if the drawings will one, that is the water front, if the two valve that is behind the water meter,

Q:The two valves are available for the flow of the electromagnetic valve switch, I contact more, found for water solenoid valve are caged water, to repair several times because of impurities or newly installed pipeline with raw materials flowing through the valve, close the valve body when not to rely on Yan, a seepage water tank to diffuse phenomenon!I am looking for a replacement, I think the electric valve should be a good choice, not used to a conclusion.Please use the electric ball valve to talk about friends, or for the two kinds of friends who have an understanding to talk aboutOr there is no better substituteThere seems to control the solenoid valve and electric valve is not the same, the solenoid valve is normally open and closed to control the electric valve is controlled by the trigger (like), if used to replace it, what is the controller?: Solenoid valve on the medium cleanliness requirements are very high, when the water is not clean, easy to leak. You use the solenoid valve is leaking, that's the case.If you have an air source, use pneumatic angle seat valvesIf only the power supply, the electric ball valve.Electromagnetic valve is electromagnetic rail, electric suction from the electromagnetic core, so that the valve openThe electric ball valve is driven by the motor to drive the valve open. If only switch, then do not need to install any controller, when buying, must explain is the switch ball valve.This answer was net friend adoption

Q: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
