Industrial valves are critical components in piping systems and fluid transfer operations, designed to **control pressure, flow rate, and fluid direction**. Depending on operational requirements and working conditions, they come in a wide range of types. **Gate valves** are used for full shut-off applications and are typically produced in sizes ranging from **DN50 to DN1200**, with pressure classes from **PN10 to PN40** and standards such as **ANSI Class 150 to 600**. **Globe valves**, designed for precise flow regulation, feature an S-shaped flow path which causes higher pressure drop, and are available in sizes **DN15 to DN600** with pressure ratings from **PN16 to PN100**. **Ball valves**, well-known for their **tight sealing and quick 90-degree operation**, are manufactured in sizes from **1/2 inch to 24 inches**, with working pressures ranging from **150 to 2500 psi**. **Butterfly valves**, ideal for large systems with space constraints, are commonly available in dimensions from **DN50 to DN2000**, with pressure classes of **PN6 to PN25**, serving various industries.
Depending on the application, industrial valves feature different material specifications and technical standards. In oil, gas, and petrochemical sectors, valves are commonly made of **carbon steel ASTM A216 WCB** or **stainless steel ASTM A351 CF8M** and certified under standards such as **API 600, API 6D, or ANSI B16.34**. For high-temperature applications up to **+450°C** and working pressures up to **250 bar 25 MPa**, special high-pressure valves are used. In food and pharmaceutical industries, **316L stainless steel** is typically selected for valve bodies, offering polished surfaces suitable for hygienic requirements, compliant with **FDA and 3A Sanitary** standards. Adhering to these specifications and selecting valves according to **fluid type, pressure, and operating temperature** plays a critical role in minimizing leakage risks, extending equipment lifespan, and optimizing industrial processes.
