Features

Benefits

Pressure-Activated Seal

Sealing force increases with system pressure, eliminating bonnet leakage even at extreme pressures (up to CLASS 4500).

One-Piece Bonnet Design

Reduces potential leak paths compared to multi-bolt bonnet valves, enhancing safety in toxic or flammable service.

Hardened Trim Components

Disc and seat materials (e.g., Stellite, Inconel) resist erosion and galling, extending service life in abrasive media.

Quick-Change Trim

Allows for in-line maintenance of seals and discs without removing the valve from the pipeline, minimizing downtime.

Blowout-Preventive Stem

Designed to prevent stem ejection under pressure, meeting API 600 safety standards for critical service.
