Introduction to Jacketed Plug Valve
1. Scope of application
The standard plug valve is suitable for satisfying the function of the ordinary plug valve, and is an improvement to the condition that the medium is easy to solidify or crystallize at room temperature.

2. Model specifications
National standard plug valve

Pressure range (MPa)	Nominal diameter (mm)
PN1.0-5.0	DN15-400

4. Performance characteristics
A new type of thermal insulation jacketed plug valve. The valve body shell is provided with a jacket for thermal insulation. The jacket and the valve body together form a thermal insulation chamber; there are jacket ports installed on the two sides of the valve body, which can pass steam or other overheating. Gas to protect the medium in the valve from solidification or crystallization at room temperature. In the case of the same caliber, the connection size of the thermal insulation plug valve is one to two specifications larger than that of the ordinary plug valve.
