Frequently Asked Questions
Q1: What is a 5000 PSI Ball Valve?
A: A 5000 PSI Ball Valve is a high-pressure valve rated for up to 5000 PSI, designed to provide reliable shut-off and flow control in industrial pipelines, オイルを含む & ガス, 石油化学, and power generation systems.
Q2: What does “trunnion-mounted” mean?
A: In a Trunnion Mounted Ball Valve, the ball is supported at the top and bottom (trunnions), reducing seat wear, lowering actuation torque, and enabling high-pressure operation with minimal leakage.
Q3: What is DBB capability and why is it important?
A: Double Block & Bleed (DBB) Ball Valves provide independent upstream and downstream isolation with a cavity vent, improving operational safety during maintenance or pipeline shutdowns.
Q4: Can it handle sour or corrosive media?
A: はい, with appropriate material selection such as duplex or super duplex stainless steel and fire-safe seals, it is suitable for H₂S, sour, or corrosive service.
