Product Guide & Technical Article

Industrial Valves: Selection Guide for Process Applications

Valves control the flow, pressure, and direction of fluids in piping systems. Selecting the correct valve type, material, and pressure rating is critical for safe and efficient plant operation.

Types of Industrial Valves

Ball Valves — quarter-turn operation, excellent shutoff, low pressure drop. Gate Valves — full bore, minimal restriction, for on/off service. Globe Valves — precise flow regulation, higher pressure drop. Check Valves — prevent backflow automatically. Needle Valves — fine flow control for instrumentation. Butterfly Valves — compact, lightweight, for large diameter lines.

Material Selection

Stainless Steel (CF8/CF8M equivalent to SS304/316) for corrosive service. Carbon Steel (WCB) for general industrial service. Bronze and brass for water and low-pressure applications. Duplex and Super Duplex for offshore and highly corrosive environments.

End Connections

Available with flanged (ASME B16.5), screwed (NPT/BSP), socket weld, and butt weld end connections. Pressure ratings from Class 150# to Class 2500#.

Testing & Certification

All valves tested to API 598 / BS 6755 standards for shell test, seat test, and backseat test. Fire-safe designs available to API 607 / API 6FA. Third-party inspection by TUV, DNV, Bureau Veritas available.
