Features

- One-piece body with ultra-short face-to-face dimension; weight approx. 50% of comparable standard ball valves.
- Bi-directional spherical seats for zero-leakage (bubble-tight) service.
- Ball port options: rectangular, V-port, or full-bore.
- Spring-return pneumatic piston actuator (single-acting); fails closed on loss of air supply.
