Double Ball Valves (Manual Operated, Model RVB-DBV)

Double ball valves are designed to provide enhanced safety and isolation by integrating two independent ball valves within a single body or block. This configuration allows for the isolation of pressure from both upstream and downstream sides with minimal space requirements. Built to API 6A standards, these manually operated valves are ideal for critical oil and gas applications where redundancy and reliability are essential.

Features & specifications

  • Two Independent Ball Valves in One Block: The double valve design offers dual isolation in a single, compact body, reducing installation space and improving operational efficiency.
  • Enhanced Safety: Each ball valve operates independently, providing an additional layer of isolation in high-pressure systems. This is especially useful in applications where complete redundancy is required for safe operation.
  • Bi-directional Flow: Each ball valve supports bi-directional flow control, ensuring flexibility and versatility in operation.
  • Compact Design: By combining two valves in one block, the design reduces the need for extra piping and fittings, leading to lower installation costs and fewer potential leakage points.
  • Manual Operation: Both ball valves are manually operated using hand levers, offering simple and reliable control over the flow, with no need for additional actuation mechanisms.
  • Spring-Loaded Seats: The spring-loaded floating seats maintain contact with the ball even under low pressure, ensuring a reliable seal at all times.

Sizes:

  • Available in sizes from 2 1/16” to 4 1/16”.

Pressure Ratings:

  • Suitable for pressure ratings of 3000 psi (210 bar) to 5000 psi (350 bar).
