- 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.
- Opsi Aktuasi
Actuator Type | Keterangan |
Lever Handle | Standard manual operation, with locking plate in open/closed position |
Gear Operator | For higher torque or larger sizes (optional for 2″) |
Pneumatic Actuator | Double‑acting or single‑acting (spring return) for on‑off or modulating service |
Electric Actuator | For remote automated control with position feedback |
