  1. Design Features & Requirements
  1. 3-Piece Bolted Body: The body consists of three parts (Body + 2 End Caps) bolted together. This allows for easy maintenance (seat/ball replacement) without removing the entire valve from the pipeline.
  2. Trunnion Mounted Ball: The ball is fixed and supported by upper and lower stems/bearings. This design is ideal for 20″ large bore applications, reducing operating torque and ensuring stable performance under high differential pressure.
  3. Double Piston Effect (DPE) Seats: Standard seats provide bidirectional sealing. The valve typically features automatic cavity pressure relief (the upstream seat acts as a piston, allowing overpressure in the body cavity to vent into the pipeline).
  4. Emergency Sealant Injection: The valve body is equipped with sealant injection fittings. In case of seat damage, sealant can be injected to temporarily restore sealing.
  5. Dispositivo antistatico: A spring-loaded plunger/ball ensures electrical continuity between the ball, stem, and body to prevent static spark buildup.
  6. Secondary Metal Seal: In the event the soft seat is destroyed by fire, the ball will contact the metal seat support, providing a metal-to-metal seal (Fire Safe feature).

Note:

  • This data sheet is based on standard ASME/API specifications.
  • The gearbox dimensions (height, handwheel size) and overall weight may vary depending on the manufacturer and gearbox model. Please refer to the final manufacturer’s drawing for certified dimensions.

  1. Design Features & Requirements
  1. 3-Piece Bolted Body: The body consists of three parts (Body + 2 End Caps) bolted together. This allows for easy maintenance (seat/ball replacement) without removing the entire valve from the pipeline.
  2. Trunnion Mounted Ball: The ball is fixed and supported by upper and lower stems/bearings. This design is ideal for 20″ large bore applications, reducing operating torque and ensuring stable performance under high differential pressure.
  3. Double Piston Effect (DPE) Seats: Standard seats provide bidirectional sealing. The valve typically features automatic cavity pressure relief (the upstream seat acts as a piston, allowing overpressure in the body cavity to vent into the pipeline).
  4. Emergency Sealant Injection: The valve body is equipped with sealant injection fittings. In case of seat damage, sealant can be injected to temporarily restore sealing.
  5. Dispositivo antistatico: A spring-loaded plunger/ball ensures electrical continuity between the ball, stem, and body to prevent static spark buildup.
  6. Secondary Metal Seal: In the event the soft seat is destroyed by fire, the ball will contact the metal seat support, providing a metal-to-metal seal (Fire Safe feature).

  • The gearbox dimensions (height, handwheel size) and overall weight may vary depending on the manufacturer and gearbox model. Please refer to the final manufacturer’s drawing for certified dimensions.

 

GARANZIA:

SAVVY VALVES si impegna a fornire una qualità di prodotto eccezionale e un servizio post-vendita senza pensieri.
