Q:What are the differences between the lever ball valve and the handwheel ball valve? What are their differences?

Group pairs of valves, have not heard of a lever type ball valve, only lever type safety valve, hand wheel type is only the way it drives different, the way is also ever-changing, to see the needs of individuals

Q:Pneumatic ball valve q641f-16p what do you mean?

Q is a ball of the code, 6 representative driving mode is pneumatic, 4 flanged ball valve structure is straight through channel 1 on behalf of the floating ball, f sealing surface is the fluorine plastics, 16 represents the pressure of 16 kg, P represents the body material is stainless steel, Shandong Huadian valve.

Q:Ball valve specifications 1/2 inches corresponding to DN?

I know that. 1/2 stands for DN15. 3/4 stands for DN20. Ha ha, unfortunately no points

Q:The hot water pipe ball valve what brand alone?

Angle valve is mainly suitable for heating pipes. Usually a connecting point between the hose and the wall that is attached to the wall and attached to the faucet above.

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

1/2 equivalent to the national standard of 15mm, 3/4 equivalent to GB 20mm. That is, DN15 and DN20

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:What does "q41f46-16c-dn40" mean?

DN40 refers to the nominal diameter, 16C represents 16 kg of pressure, carbon steel material F46 stands for fluorine

Q:Butterfly valve, globe valve, ball valve used what is different

Butterfly valve, globe valve, ball valve used in different occasions:1. valve (Butterfly Butterfly) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closure of a valve, the main cut off on the pipe and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve.Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe.

Q:One stainless steel ball, two pieces, three pieces of difference, use

A piece of ball valve, that is, the principle of Canton style ball valve is to rely on rotary valve to make the valve open or blocked. Valve switch light, small size, can be made large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries.

Q:Replacement method of PPR hot melt ball valve

1, need to replace the valve, if the valve is flange or wire connection type, directly open flange or loosen the screw, the ball valve can replace a broken;
