8. Key Features
-
Floating ball design – Ball is supported by seats on both ends; medium pressure pushes the ball against the downstream seat for tight shut-off; ideal for small to medium bore (DN ≤ 200)
-
Stainless steel body – Excellent corrosion resistance; suitable for chemical, food, pharmaceutical, seawater, and other demanding services
-
Bi-directional sealing – PTFE seats provide zero leakage shut-off
-
Low operating torque – Lower torque compared to trunnion ball valves; allows use of compact electric actuators
-
Fire safe design (optional) – Compliant with API 607; retains certain sealing integrity after fire exposure
-
Anti-static device (optional) – Prevents electrostatic charge accumulation
-
Motorized actuator – Enables remote on/off, local operation, and signal feedback for automated control
