Explore our high-performance 2-inch butterfly valves and matching pipeline hardware designed for extreme thermal and fluid pressure conditions.
Within modern industrial piping systems, the 2-inch butterfly valve (DN50) serves as a critical standard for pressure regulation and reliable isolation. Due to their compact size, lightweight structure, and fast 90-degree rotary operation, these valves are highly valued across municipal water works, chemical processing facilities, marine environments, and manufacturing operations globally.
Selecting a high-quality supplier is key. At KR, we deliver advanced metallurgical performance and elastomeric seal integrity, ensuring every valve meets structural standards like API 609, ASME B16.34, and EN 593. Whether utilizing a standard lever, high-reduction gear box, or automated pneumatic actuator, our 2-inch configurations prevent pressure losses while maintaining bubble-tight shutoff.

Understanding the mechanical properties of materials and seating components is critical to selecting the proper configuration for specific chemical and thermal environments.
Features a centralized shaft and symmetrical disc design. Uses high-grade EPDM or NBR liners to provide an elastic, bubble-tight seal. Best suited for municipal water distribution, HVAC, and low-pressure wastewater treatment systems.
Specially engineered for corrosive chemical environments. The body is lined with pure PTFE or PFA, protecting structural metals from aggressive acids, alkaline solutions, and harsh organic solvents.
Uses a multi-eccentric design that eliminates friction between the seal and disc during operation. Standard configuration for high-temperature and high-pressure steam systems, refineries, and oil & gas pipelines.
