  1. 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.
  1. Performance Features
  1. Soft Seated Floating Ball – Bubble‑tight shut‑off in both directions (zero leakage per API 598 / ISO 5208 Rate A).
  2. Precision Cast Body – Smooth internal surface reduces pressure drop and extends seat life.
  3. Low Operating Torque – Polished ball and low‑friction PTFE seats ensure easy manual or actuated operation.
  4. Bidirectional Sealing – No preferred flow direction; simplifies installation.
  5. Fire Safe Design (Optional) – Secondary metal‑to‑metal sealing meets API 607 / ISO 10497.
  6. Anti‑Static Device – Available to dissipate static charge across the ball, stem, and body.

  1. Ordering Information

When ordering, please specify:

  • Valve size: 2″
  • Pressure rating: Class 150
  • End connection: Flanged RF
  • Body material: WCB / CF8 / CF8M
  • Seat material: PTFE / RTFE / PEEK
  • Operation: Lever / Gear / Pneumatic / Electric
  • Special requirements: Fire safe, anti‑static, low‑emission packing, NACE MR0175, etc.

Notes:

  • Silica sol casting ensures a high‑quality surface finish, making this valve suitable for critical services and automated actuation.
  • For stainless steel bodies (CF8/CF8M), the same silica sol process applies, offering excellent corrosion resistance.
  • Final dimensions and weights may vary slightly by manufacturer; refer to approved drawings for exact values.
