Trunnion mounted ball valve is applicable for high pressure, larger caliber pipelines. It can transmit corrosive medium containing hydrogen sulfide and impurities in gas pipelines.
Characteristics
1. Base adopts spring. The spring pushes base to ball to ensure good seal under low pressure.
2. Trunnion mounted ball valve realizes double seal.
