BZ41W insulation gate, turn the handwheel by hand wheel and screw thread of the valve stem of the advance and retreat, lifting or lowering the valve plate connected to the valve stem, reach the role of opening and closing.

Working principle of the product and application:

BZ41W insulation gate, turn the handwheel by hand wheel and screw thread of the valve stem of the advance and retreat, lifting or lowering the valve plate connected to the valve stem, reach the role of opening and closing.

Insulated gate valve is mainly used in oil, chemical, metallurgical, pharmaceutical and other kinds of systems, in order to transport under normal temperature solidification of high viscosity medium.

Product structure features:

1. Jacketed welding in valve between the flanges, the side of the valve, connection Settings are at the bottom of the jacket.

2. The connecting flange size larger than the same specifications ordinary valve connecting flange to the two specifications, the length of the structure with the same specifications of the common valve is the same.

3. In the jacket can be freely through the steam or other heat insulation medium, to ensure that the viscous medium can be smoothly through the valve.
