Triple Offset - Tri Lok®-Cx Triple Offset - Tri Lok®-Cx

Tested for Fugitive Emissions: Certified to ISO 15848-1 for Emission Control

High-Performance Valve for Petrochemical and Power Sectors

Tri Lok® is the premier isolation valve for operation in vacuum to high-pressure applications. The non-rubbing, metal-tometal seal delivers zero-leakage bidirectional shutoff with minimal torque, and is certified fire-tested. Compared to gate, globe, or ball valves of the same size and pressure class, Tri Lok provides space and weight savings, while minimizing installation and maintenance costs.

Features & Benefits

  • A. Seat & Seal System

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

  • B. Enhanced Seat Hardness

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

  • C. Sealing System

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

  • D. Seal Ring

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

  • E. Splined Disc-to-Stem Connection

    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.

  • F. Stem Packing

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

  • G. Blowout-Proof Stem

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

  • H. Indexed Stem

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

  • I. Elongated Stem Bearings

    Hardened bearings provide maximum stem support.
