BALL VALVES — Technical Overview & Selection Guide

BALL VALVE TYPES

Overview

Ball valves are quarter-turn rotary valves designed to provide reliable on/off flow control in piping systems. They operate by rotating a spherical ball with a bore through its centre to allow or block fluid flow. Ball valves offer quick operation, tight shut-off, low pressure drop, and dependable sealing performance.

They are widely used in water supply, oil and gas, chemical processing, power generation, and industrial applications. Depending on their design, ball valves are suitable for a wide range of operating pressures, temperatures, and fluid services.

1. Floating Ball Valve

Compact design for general process isolation. Available in 1-PC, 2-PC and 3-PC construction, with Full Bore or Reduced Bore options.

2. Trunnion Mounted Ball Valve

Mechanically supported ball design for large sizes, higher pressure and critical isolation. Suitable for automated and pipeline applications.

3. Full Bore / Reduced Bore

Full Bore: Low pressure drop and unrestricted flow.

Reduced Bore: Compact, lighter and economical for general process applications.

4. V-Port / Segmented Ball Valve

Designed for throttling and modulating control. Suitable where controlled flow characteristics are required.

5. 3-Way & Multi-Port Ball Valve

Available in L-Port and T-Port configurations for flow diversion, mixing and multi-line process routing.

6. Metal Seated Ball Valve

Designed for high temperature, abrasive and severe service applications where conventional soft seats are unsuitable.

7. Soft Seated Ball Valve

Available with PTFE, RPTFE, PEEK and other engineering polymer seats for reliable sealing and chemical compatibility.

8. Top Entry Ball Valve

Maintenance-oriented design allowing access to internal components from the top, suitable for critical installations.

9. Cryogenic Ball Valve

Specially designed for LNG, industrial gases and low-temperature applications with extended stem/bonnet configuration.

10. Fire Safe Ball Valve

Suitable for critical hydrocarbon applications with fire-safe construction as per applicable project specifications.

11. DBB Ball Valve

Double Block & Bleed configuration for critical isolation and cavity pressure management applications.
