Product description

Parameters

Jacket insulation ball valve is mainly used in petroleum, chemical, pharmaceutical, metallurgy, electric power and other kinds of systems, in order to transport under normal temperature solidification of high viscosity medium. The ball valve jacketed welding between the ends of the valve sealing surface, sides and bottom of the valve is equipped with jacketed heat medium connectors. Due to the increased the jacket, this kind of valve end connection size larger than the size of the same specification to the two specifications. The valve end connection type has two kinds of flange and butt weld ends. Freely in the jacketed by steam or heat conduction oil medium, to ensure that the viscous medium flow through the valve.

Design specification: GB/T 12237 API 6d API 608 BS 5351

Flange connection: GB/T 9113 ASMEB16.5

The test and inspection: GB/T 13927API598API6d
