IV. Dimensions & Weight (Reference, Full Bore)

Size Pressure Class Flange Standard Face‑to‑Face L (mm) Center Height H (mm) Flange OD (mm) Weight (kg)
1-1/2″ Class 300 ASME B16.5 RF ~190 ~110 ~200 approx. 8–12 (carbon steel)

  • Face‑to‑face per ASME B16.10 (long or short pattern); refer to manufacturer data.

  • Flange dimensions: OD approx. 200 mm for Class 300, 1-1/2″, bolt holes 4×φ22.

  • Jacket connections are typically 1/2″ NPT female threads on both sides of the valve body.

V. Jacket Design Features

Parameter Description
Jacket Coverage Covers entire body and part of the ends to ensure even heating of the ball cavity
Heating Media Steam, hot water, thermal oil
Maximum Jacket Pressure 1.6 MPa (higher on request)
Maximum Jacket Temperature Depends on body material and seals; typically ≤300°C
Connection Type One NPT female thread on each side (inlet/outlet); flanged connections optional
Jacket Material Usually same as body or carbon steel (economical)
Welding Requirement Full penetration weld between jacket and body; pressure tested

VI. Key Features

  1. Integral Jacket Design – Maintains media temperature inside the valve, preventing solidification or viscosity increase. Ideal for crystallizing or high‑viscosity fluids.

  2. Floating Ball Construction – Bidirectional sealing, quick shut‑off, low flow resistance.

  3. Multiple Seat Options – PTFE / RPTFE / PEEK / metal, for various temperature and wear requirements.

  4. Full Bore or Reduced Bore – Full bore recommended to minimise pressure drop and dead zones.

  5. Anti‑static & Blow‑out Proof Stem – Standard for enhanced safety.

  6. Flanged Connection – ASME B16.5 Class 300 RF, easy installation.

  7. Fire Safe Design Available – Compliant with API 607 upon request.

VII. Applications

  • Petrochemical: bitumen, heavy oil, wax, polymer transfer

  • Food industry: chocolate, syrup, fats, oils

  • Pharmaceutical: hot melt materials, ointments

  • Coatings & adhesives: hot melt adhesives, paints, resins

  • Molten sulphur, molten salt systems

  • Pipelines requiring steam tracing or electric heat tracing

VIII. Testing & Inspection

Test Item Standard Requirement
Shell Strength (Main Valve) API 598 1.5× rated pressure, no visible leakage
Low Pressure Seat Test API 598 0.6 MPa air, no visible bubbles
High Pressure Seat Test API 598 1.1× rated pressure, zero leakage across seats
Jacket Strength Test Per design pressure 1.5× jacket design pressure, no leakage
