The ASME B16.34 standard specifies requirements for cast steel butterfly control valves, including test pressures. According to this standard, the shell test pressure must be at least 1.5 times the pressure rating at 38°C (100°F), rounded up to the nearest 1 bar (25 psi) increment. This ensures the valve’s durability and performance under pressure.

As a leading control valve manufacturer, we adhere to ASME B16.34 standards, providing high-quality butterfly control valves that meet rigorous testing and reliability requirements for various industrial applications.
