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 LNV 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.
