3. 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.

4. 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.

5. Actuation Options

Actuator Type Description
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

6. Applications

  • Water treatment and distribution

  • Oil and gas gathering lines

  • Chemical and petrochemical process lines

  • HVAC systems

  • Food and beverage (with stainless steel body)

  • General industrial utilities

7. Testing & Compliance

Test Standard / Requirement
Shell Test 1.5 × Class 150 (2.2 MPa / 319 psi) – no visible leakage
Seat Test 1.1 × Class 150 (1.6 MPa / 232 psi) – zero leakage (Rate A)
Low‑Pressure Seat Test 0.6 MPa (87 psi) – zero leakage
Material Traceability EN 10204 3.1 (optional)
Marking Per MSS SP‑25 / API 608

8. 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.
