8. Key Features
-
2-piece body – Easy inline maintenance; seats and seals can be replaced individually
-
Floating ball design – Ball is supported by seats on both ends; medium pressure pushes the ball against the downstream seat for tight shut-off
-
Full bore – No flow restriction; ideal for low pressure drop applications
-
Bi-directional sealing – PTFE seats provide zero leakage shut-off
-
Motorized actuation – Enables remote on/off, local operation, and signal feedback for automated systems
-
Anti-static device (optional) – Prevents electrostatic charge accumulation
-
Fire safe design (optional) – Compliant with API 607
