BQ41F-16P Carbon Steel Manual Thermal Insulation Ball Valve With Flange Connection Manufacturers

Product Description

• The flange thermal insulation ball valve is an integral thermal insulation ball valve that is composed of a valve body, an end cover, a valve seat, a ball, a valve stem and a driving device. It has thermal insulation and cold insulation properties. The valve body is equipped with a valve surrounding the valve body and a There is an insulating jacket for the heat source inlet and one heat source outlet. The valve has an integrated structural design without middle flange, left body and right body connection, which reduces the leakage rate. The flange adopts a variable diameter enlarged flange, which increases the space inside the jacket so that it has enough heat source to prevent the medium from crystallizing and maintain fluid fluidity.

Product dvantages:

• The end cover of the flange insulated ball valve is designed with a flange screw cover. The connection is tightly matched with threads and sealed with a gasket. During installation, the flange and gasket of the pipe are added to achieve a double sealing effect.
