Wafer Type Concentric Butterfly Valve

Compact, lightweight flow control valve designed for space-saving and cost-effective fluid regulation. Its centerline design aligns the disc symmetrically within the seat, providing a tight seal with minimal torque. The wafer-style body fits between two pipeline flanges, making it easy to install and remove. With a soft elastomer seat (such as EPDM or NBR), it delivers excellent leak-tight sealing for a variety of general-purpose applications.


    Benefits

    • Compact & lightweight: Ideal for space-constrained installations


    • Reliable sealing: Resilient seat provides tight shutoff in both directions


    • Quick installation: Wafer design fits between flanges without extra hardware


    • Low torque operation: Reduces actuator size and energy consumption


    • Cost-efficient: Affordable solution for common flow control needs


    • Versatile actuation: Compatible with manual, pneumatic, or electric actuators
