Floating ball valves are widely used in industrial piping systems for on/off control due to their simple design, reliable sealing, and ease of operation. One of the most critical factors influencing valve performance is the seat material. In industrial applications, floating ball valves are commonly offered with soft seats or metal seats, each with distinct advantages and limitations.

Lubricated plug valves have been a mainstay in oil and gas pipeline systems for decades. Known for their robust construction, reliable sealing performance, and low maintenance requirements, these valves are particularly suited for the demanding conditions found in upstream, midstream, and downstream operations.

Double Block and Bleed (DBB) ball valves are widely used in oil and gas, petrochemical, chemical processing, and industrial pipeline systems where reliable isolation is critical. Among the various components that determine valve performance, the seat material plays a vital role in sealing efficiency, operating torque, and service life. Polytetrafluoroethylene (PTFE) has become one of the most commonly used seat materials in industrial DBB ball valves due to its excellent sealing characteristics and broad chemical compatibility.

In modern industrial facilities, equipment layouts are becoming increasingly compact due to space constraints, modular construction requirements, and the growing demand for efficient plant design. As a result, valve manufacturers have developed compact trunnion mounted ball valves that provide reliable shut-off performance while minimizing installation space. These valves combine the advantages of traditional trunnion-mounted designs with a reduced footprint, making them ideal for applications where available space is limited.

​Trunnion mounted ball valves are widely used in industries where high pressure, large diameter, and challenging process conditions demand reliable flow control. One critical factor in ensuring the longevity and performance of these valves in corrosive environments is the selection of suitable materials for the body, ball, seat, and stem. This article explores material options, considerations, and best practices for trunnion mounted ball valves operating in corrosive media.
