Triple Offset

The fully field-replaceable seat & seal extends overall life, minimizes downtime, and reduces the need for costly off-site repairs or total replacement.

Eliminates risk of seat/seal galling, offering superior performance, durability, and abrasion resistance compared to other materials.

The non-rubbing, metal-to-metal sealing system is inherently firesafe and fire-tested, while meeting zero-leakage requirements for many critical applications.

Offers a flexible design and wide range of materials to provide torque-loaded sealing with zeroleakage. (Optional solid seal ring available.)

The strong and reliable connection allows for axial movement of the stem independent of the disc, to protect the disc/stem connection from temperature fluctuations and pressure effects. This connection prevents typical misalignment problems of rigidly attached discs and stems, minimizes hysteresis, eliminates external connections & associated hardware, and allows for easy assembly & disassembly.

Fully-adjustable, field-replaceable stem packing is certified to international fugitive emission standards.

One-piece stem features blowout prevention ring located outside of the pressure boundary, as well as redundant blowout prevention mechanisms.

Provides positive visual indication of disc/seal ring position after installation.

Hardened bearings provide maximum stem support.
