Can the structure of forged steel globe valves reduce unnecessary homeopathy?

Release time: 2018.12.20 viewed:  
  

The most obvious advantage is that in the process of opening and closing, the friction between the disc and the sealing surface of the valve body is smaller than that of the gate valve, so it is wearable. The opening height is generally only one fourth of the diameter of the seat passage, so it is much smaller than the gate valve. Usually there is only one sealing surface on the valve body and disc, so the manufacturing process is better and easy to maintain. Nominal pressure or pressure level: PN1.0-16.0 MPa, ANSI CLA...


Forged steel globe valve includes valve body, valve cover and stem. The product valve cover is installed on the upper part of the valve body. The lower part of the product valve stem is placed in the valve body and is equipped with a valve ball at the lower end of the valve stem. The upper part of the valve stem passes through the valve cover and is equipped with a handwheel at the upper end of the valve stem. The lower end of the product stem is equipped with a valve ball fixing sleeve through threads. The diameter of the lower part of the product valve ball fixing sleeve is smaller than that of the valve ball. Diameter, product valve ball is placed in the inner cavity of the ball fixing sleeve. When the valve ball is damaged, the valve body and cover are separated first, and then the ball fixing sleeve on the stem can be removed to replace the valve ball conveniently without replacing the stem together, thus reducing unnecessary losses.

Usually there is only one sealing surface on the valve body and disc, so the manufacturing process is better and easy to maintain. Nominal pressure or pressure level: PN1.0-16.0 MPa, ANSI CLASS 150-900, JIS10-20K nominal diameter or caliber: DN10-500, NPS 1/2-36 "connection mode: flange, butt welding, threads and other applicable temperatures: -196 ~700 C driving mode: manual, bevel gear transmission, pneumatic, electric, hydraulic, pneumatic, electro-hydraulic, electro-hydraulic valve body materials: WCB, ZG1189Ti, ZG118Ni12Mo2Ti CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti.


Different materials can be used in water, steam, oil, nitric acid, acetic acid, oxidizing media, urea and other media.
