What does it mean to say 11 4 304 on the ball valve

Hello, dear and happy, it is a pleasure to serve you: the ball valve says 11 4 304 stands for stainless steel, and the 304 sanitary ball valve is the stainless sanitary steel ball valve. 11 4 indicates that the length of the valve is 11, and the diameter is the specification of the pipe itself expressed in inches.

It's an inch of pipe. There are three more general representations: 1 1 4"(Note that there is a space -1 4.)""Indicates inches.

1 1/4"Equivalent to DN32 in the metric system. They are all nominal diameters of the tubes, i.e., nominal diameters.

For pipes, it is expressed as a size smaller than the outer diameter and larger than the inner diameter. Corresponding to a certain nominal diameter of the pipe, its outer diameter is a certain value, and the inner diameter varies with the wall thickness. The valve is engraved with 304, which means that the material used for this valve is made of 304 stainless steel.

Stainless steel material is also divided into a variety of materials, there are 304, there are 316, there are 2205, different types of search and regret number have different uses and advantages, 304 can be used as a food-grade stainless steel material, the size of the valve is not represented by 304, the size of the valve should be expressed by how much DN, pay attention to the valve has a mark. Thank you for your trust, the above is my reply, I hope it can help you, I wish you a happy life.

1 2 is the American standard.

Represents 1 2 inches. Equivalent to the national standard.

DN15, nominal diameter.

15mm, which means that the inner diameter of the pipe is 15mm. In the water raid search key warm industry is called 4 points.

Comparison of common specifications of valves:

Mouth leakage is called - American standard - national standard.

4 points - 1 2 - DN15

6 points - 3 4 - DN20

1 inch - 1 - DN25

1 inch 2 - shoot Qiao - 1 and 1 4 - dn32

1 and a half inches - 1 and 1 2 - DN40

2 inches - 2 - DN50

Dear, hello, I'm glad to answer for you, what does valve 4 mean Answer: valve 4 means that it means that the inner diameter of the roll gap grip on behalf of the valve connection port is 20mm, and 3 4 is the imperial 3 4 inches, which is usually said to be 6 points according to the nominal diameter (1) small bore valve: the nominal bore Daqing DN 40mm valve.

2) Medium bore valve: valve with nominal bore DN of 50 300mm. (3) Large bore valve:

Valves with nominal diameter DN of 350 1200mm. (4) Extra-large bore valve: valve with nominal bore DN 1400mm.

According to the nominal pressure: (1) Vacuum valve: refers to the valve whose working pressure is lower than the standard atmospheric pressure.

2) Low-pressure valve: refers to the valve with nominal pressure pn. (3) Medium pressure valve:

Refers to a valve with a nominal pressure of pn. (4) High-pressure valve: refers to the valve with nominal pressure pn.

5) Ultra-high pressure valve: refers to the valve with nominal pressure pn.
