Soft Seal Trunnion Ball Valve

Introduction

 

The Soft Seal Trunnion Ball Valve is a valve that uses soft sealing materials (such as polytetrafluoroethylene PTFE, nylon, rubber, etc.) as the valve seat sealing element. The ball is fixed by bearings or supports at the upper and lower ends and does not move with the medium pressure. Therefore, it is called a "fixed ball" structure. It is suitable for large-diameter or high-pressure conditions.

 

 

Applications

 

Petrochemical
Controls the flow and isolation of crude oil, refined products, and chemical intermediates in pipelines, ensuring stable operation and leak-free performance under high pressure.

 

Natural Gas Transmission
Provides reliable shut-off and flow regulation for high-pressure gas pipelines, supporting automated control and protecting downstream equipment.

 

Power Generation
Manages steam, cooling water, and process fluids, allowing safe isolation and precise flow control under high-temperature and high-pressure conditions.

 

Water Treatment
Regulates and isolates water and wastewater pipelines, ensuring stable flow, leak prevention, and safe maintenance in large-diameter systems.
