Silica Sol Casting Advantages

Superior Surface Finish – Reduces fugitive emissions, minimizes seat wear, and ensures reliable ball‑seat contact.
High Dimensional Accuracy – Consistent flange alignment and ball cavity dimensions, critical for automated actuation.
Defect‑Free Structure – Almost no porosity, inclusions, or shrinkage defects compared to sand casting.
Thin‑Wall Capability – Allows lighter weight without compromising mechanical strength.

Performance Features

Soft Seated Floating Ball – Bubble‑tight shut‑off in both directions (zero leakage per API 598 / ISO 5208 Rate A).
Precision Cast Body – Smooth internal surface reduces pressure drop and extends seat life.
Low Operating Torque – Polished ball and low‑friction PTFE seats ensure easy manual or actuated operation.
Bidirectional Sealing – No preferred flow direction; simplifies installation.
Fire Safe Design (Optional) – Secondary metal‑to‑metal sealing meets API 607 / ISO 10497.
Anti‑Static Device – Available to dissipate static charge across the ball, stem, and body.
