30インチ 600ポンド 3ピース トラニオンボールバルブ（鋳鋼製）

The 30″ 600LB 3-piece trunnion ball valve in cast steel is built for heavy-duty industrial applications that demand reliable sealing and high flow capacity, such as oil and gas pipelines, petrochemical plants, and water distribution networks. Its large 30-inch bore and Class 600 pressure rating allow it to handle high-pressure, high-volume flow with minimal pressure drop. The trunnion-mounted ball design reduces operating torque by absorbing line pressure through the fixed shaft supports, which ensures stable operation and enhanced sealing performance. The 3-piece body construction allows for easier maintenance and in-line servicing without removing the entire valve from the pipeline. Cast steel offers excellent strength, corrosion resistance, and structural integrity under demanding conditions. This valve is typically automated for remote or emergency actuation and is valued for its durability, ease of operation, and safety in high-pressure systems where dependable isolation is critical.
