V. Jacket Design Features

Parameter Description
Jacket Coverage Covers entire body and part of ends for even heating of 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 or BSP female thread on each side (inlet/outlet); flanged optional
Jacket Material Stainless steel 304/316 (compatible with body)
Welding Requirement Full penetration weld between jacket and body; pressure tested

VI. Key Features

  1. Stainless Steel Construction – Excellent corrosion resistance for aggressive or clean media.

  2. Integral Jacket Design – Maintains media temperature, prevents solidification or viscosity increase.

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

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

  5. Full Bore – Recommended to minimise pressure drop and dead zones.

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

  7. Flanged Connection – EN 1092-1 PN100 RF, easy installation.

  8. Fire Safe Design Available – Optional API 607.

VII. Applications

  • Petrochemical (corrosive viscous media)

  • Food industry (chocolate, syrup, fats, oils)

  • Pharmaceutical (hot melt materials, ointments)

  • Coatings & adhesives (hot melt adhesives, resins)

  • Molten sulphur, molten salt systems

  • Stainless steel pipelines requiring steam or electric tracing

VIII. Testing & Inspection
