Features
- Flush mounted actuation means no brackets or couplings are required and there are fewer nuts and bolts.
- A fully adjustable stem packing allows for 180-degree wrench clearance for adjustment.
- It’s capable of sealing against pressure and vacuum without packing modification.
- The interference fit design provides a bidirectional tight shutoff.
- The extended neck provides two inches of pipeline insulation.
- The standard K-LOK flange surfaces are uninterrupted, which allows standard spiral wound gaskets to be used.
- No travel stops are required, making adjustment and maintenance much easier.
- The rocker arm packing allows for uneven tightening of the gland bolts without side loading the system packing.
- The Double offset disc design provides the disc with a camming effect that lifts the disc away from the seat, thereby reducing seat contact wear.
- A fire-safe seat configuration allows for bidirectional service and constant two-point seal of the metal and RTFE seat components. This allows partial burn of the seat without excessive leakage.
