- 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.
- Actuation Options
- Lever handle (standard)
- Gear operator (optional)
- Pneumatic or electric actuator for automation
- 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 |
Material Traceability | EN 10204 3.1 (optional) |
Note:
- Silica sol casting ensures a high-quality surface finish suitable for critical services and automated actuation.
- Final dimensions and materials can be tailored to project specifications.
