Main Features

Offset Design

1st offset: The shaft centerline is positioned behind the disc centerline, reducing contact between the disc and seat during closure and allowing continuous engagement with the seating surface.

2nd offset: The shaft centerline is offset from the valve and pipe centerline, creating a linear sealing surface. This ensures that as the valve opens, the disc seal quickly disengages from the seat, minimizing friction and wear on the sealing surfaces.

Compact Design

With a shorter face-to-face dimension and lightweight structure, it saves space in piping systems compared to other valve types.

Low Emission and Anti-Blowout Stem Design

Pre-compressed flexible graphite packing ensures lower torque and better sealing, with controlled stem and stuffing box roughness. The live-loaded gland flange allows easy packing adjustment, while the space ring and gland prevent stem blowout.
