Description

Resilient Seated Butterfly Valve – Series 3A/3AH, High-Pressure, Wafer/Lug Style

The Resilient Seated Butterfly Valve Series 3A/3AH is engineered for superior performance in demanding water, HVAC, and industrial fluid systems. Available in wafer and lug body styles, the Series 3A/3AH provides tight shut-off in both directions and meets high-pressure requirements with robust construction and versatile installation compatibility.

This valve features a high-strength ductile iron body, resilient EPDM/NBR seat, and a precision-machined disc for smooth rotation and reduced torque. The stem-to-disc connection is secure and corrosion-resistant, enhancing the valve's longevity in corrosive and abrasive environments. It is suitable for on/off or modulating service and can be actuated manually or automatically.
