The A23 Wafer Concentric Butterfly Valve is a high-performance,
compact industrial fluid control solution engineered for demanding
industrial applications. Featuring a precision-engineered
concentric design where the valve stem aligns perfectly with the
disc centerline, this valve ensures smooth operation and reliable
sealing in low-to-medium pressure systems. Constructed with robust
materials such as ductile iron, stainless steel, or specialty
alloys, and paired with corrosion-resistant EPDM, NBR, or
high-temperature Viton seals, it operates effectively across a
temperature range of -20°C to 200°C, handling diverse media
including water, steam, oils, and mild acidic/alkaline fluids.
Its space-saving wafer-style flange design simplifies installation and reduces pipeline complexity, making it ideal for space-constrained environments like municipal water supply, HVAC systems, food processing, and chemical plants. The lightweight structure, combined with low-torque operation, supports manual worm gear, pneumatic, or electric actuators for rapid response and precise flow control. Certified to ISO 5211 drive interfaces and API 609 fire-safe standards, the valve offers bidirectional sealing, a lifespan exceeding 100,000 cycles, and easy maintenance through replaceable seat seals-significantly reducing lifecycle costs. Typical applications include pump station shutoff, heat exchanger isolation, and industrial circulation control, positioning it as an optimal choice for efficiency-driven operations and cost-effective infrastructure.
