Silica Sol Casting Advantages

Superior Surface Finish – Reduces fugitive emission potential and extends seat life.
High Dimensional Accuracy – Maintains tight tolerances, ensuring consistent flange alignment and ball-seat fit.
Defect-Free Structure – Minimizes porosity, inclusions, and shrinkage defects compared to traditional sand casting.
Thin-Wall Capability – Allows lighter, more compact valve bodies without compromising strength.

Performance Features

Soft Seated Floating Ball – Bubble-tight shut-off in both directions.
Precision Cast Body – Ensures reliable sealing and extended cycle life.
Low Torque Operation – Smooth ball surface and low-friction seats.
Fire Safe Option – Available with secondary metal seat to meet API 607.

작동 옵션

Lever handle (standard)
Gear operator (optional)
Pneumatic or electric actuator for automation
