The steel PE all welded ball valve is mainly used for pipeline maintenance and reservation of pipe orifice, especially in case of pipeline failure and temporary gas cut-off in case of accident, the valve plays a particularly important role. As the control element of the pipeline, in addition to having the same pressure resistance as PE pipeline, the function of the valve is mainly embodied in two items: sealing and torque: when the valve is closed, it must have good sealing performance, which is particularly important for the gas transmission pipeline; when the valve is opened and closed, it needs relatively small torque of the valve.
Polyethylene, referred to as PE, is one of the most widely used plastics since the invention of petrochemical products. Since the 1980s, it has been gradually concerned by people because of its good physical properties, corrosion resistance, long service life, cheap price and convenient installation and maintenance. With the continuous research and development of PE materials, PE80, PE100 and other suitable for pipelines have emerged PE steel all welded ball valve for gas transmission. With the extensive use of polyethylene (PE) pipeline in various places, it is an indispensable pipeline in PE pipeline.
