  1. 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.
  1. 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.
  1. Actuation Options
  • Lever handle (standard)
  • Gear operator (optional)
  • Pneumatic or electric actuator for automation
  1. Testing & Compliance

Test

Standard

Shell Test

1.5 × rated pressure

Seat Test

1.1 × rated pressure, zero leakage per API 598 / ISO 5208 Rate A
