W-type flow regulating ball valve

Product Overview

W-type flow regulating ball valve is used in natural gas, oil, heating, chemical and thermal power pipe network and other long-distance pipeline fields, as on-off control device. The valve body is made of carbon steel or stainless steel seamless steel pipe / steel plate, and the ball has floating structure and fixed structure; the valve seat structure adopts the design of piston effect and wear compensation, and the sealing structure is designed as single and double soft sealing rings, and the metal sealing surface forms multi-stage seal with the ball body, so as to ensure the safe, reliable and long-term stable operation of the series of ball valves. The ball valve has the advantages of small volume, light weight, no leakage, no maintenance, long service life and convenient operation.

Structural characteristics

1. The valve rod can be lengthened according to the user's specific installation conditions to facilitate ground operation;
2. Compared with the conventional ball valve of the same specification, it has the advantages of small volume, light weight, beautiful appearance and durability;
3. PTFE, nylon, alloy steel, cemented carbide, etc. can be selected according to different media, which can adapt to different temperature, pressure and corrosive requirements in a wide range;
4. All welded structure, no leakage of middle flange, butt welding connection or flange connection with pipeline. The former has no leakage of pipe and valve flange connection, while the latter is easy to disassemble and repair the valve.
