BX2001 High Performance Butterfly Valve

The  BX2001 High Performance Butterfly Valve is a superior quality ASME Class 150 and 300 valve available in standard PFA, fire sealed and two metal seated versions. Offered in 2″ through 36″ sizes and in both wafer and lug body designs, all are available with a wide variety of packing options to meet your routine or most rigid service requirements.

Benefits: 

• Broad application versatility via numerous design options: wafer and lug bodies; standard PFA, optional UHMWPE, fire-sealed, Apex® and TriFlex™ seated versions; and multiple packing options
• Reduced fugitive emissions through triple-leak protection of primary stem seal plus two optional secondary seals
• Increased capacity and improved flow control with low-profile, double-offset disc
• Improved personnel and plant safety per adherence to API 609 criteria for safe, reliable anti-blowout protection

Total Quality: The BX2001 High Performance Butterfly Valve is an ideal choice for precise throttling control or on-off service with lighter weight piping systems and less expensive, energy-efficient actuators. Offered in a vast selection of materials to excel in your chemical process.

World Class Valve Performance. All castings meet rigid ASTM standards. All BX2001 valves comply with ASME B16.34, ASME B16.5, ASME B16.10, MSS SP68, MSS SP61, API 598, API 607, API 609, and ISO 5752. All PFA seated valves and optional UHMWPE seated valves are tested in accordance with ASME B 16.34 and MSS SP61. No through or external leaks are allowed, thereby exceeding the shut-off requirements of ASME/FCI 70-2 for all classes. All Apex and TriFlex metal seated valves are tested to ASME/FCI 70-2 Class IV and VI leakage rates, respectively. All valves available in ASME Class 150 and 300; DIN PN 10, -16, -20, -25 and -40 drilling.
