The Steel PE Pipeline Ball Valve is a significant research achievement by Zihigh Valve in the gas ball valve field. It is a hybrid valve that combines steel and plastic, where the main body is made from forged steel, and the connection to the pipeline is made with PE (Polyethylene) piping. This design avoids the operational failures and damage associated with aging PE material in the main body and actuator, while meeting the requirements of steel pipelines. The valve offers a long service life and high safety, with minimal risk of external leakage or failures due to PE material aging.

Types:

• Material Grades: PE80 and PE100
• Function Types: Standard, Single Vent, and Double Vent

Key Design Features:

1. Aging Resistance: The Steel PE Pipeline Ball Valve addresses leakage issues caused by material aging, as well as operational failures due to broken actuators or extended stems.

2. Direct Buried Installation: The valve can be buried directly underground without the need for a valve well, only requiring a shallow pit. It is lightweight, easy to install, and more cost-effective than fully steel valves.

3. Reliable Sealing: The valve adopts a bidirectional sealing seat structure, offering more reliable sealing compared to conventional PTFE valve seats.

4. Fire-Safe Design: The valve is equipped with a metal composite sealing seat. If the soft sealing material is burned away, the metal seat can still compress the ball under spring pressure, forming a metal-to-metal sealing structure.

5. Easy Installation: The valve can be fused to the pipeline using hot fusion or electrofusion methods.

6. Anti-Blowout Stem Design: The valve stem is designed as a blowout-proof, inverted stem with a back sealing structure and sealing gaskets. The back seal improves with increasing valve chamber pressure. The stem is sealed with O-rings, requires low operating torque, and is made from forged steel for long life and high strength.
