Wafer Centerline Butterfly Valve

A Wafer Centerline Butterfly Valve is a compact, lightweight valve designed for bidirectional flow isolation in piping systems. Unlike lug-style valves, the wafer design lacks threaded inserts and is "sandwiched" between two pipe flanges using bolts. Its centerline-mounted disc ensures minimal friction and tight sealing, even under varying pressure conditions. Ideal for space-constrained applications, these valves are widely used in water supply, HVAC, fire protection, and chemical processing due to their simplicity, cost-effectiveness, and reliability.

Performance Features

  1. Space-Saving Design: Slim profile fits tightly between flanges, ideal for cramped installations.

  2. Bidirectional Sealing: Resilient seats (EPDM, Viton) ensure zero leakage in both flow directions.

  3. Low Torque Operation: Centerline disc alignment reduces operating torque by 30–40%.

  4. High Pressure Tolerance: Rated for up to 250 PSI (ANSI 150#) and temperatures from -20°C to 150°C.

  5. Corrosion Resistance: Materials like stainless steel (SS316) and epoxy-coated cast iron enhance longevity.

  6. Fast Actuation: Compatible with manual levers, gearboxes, or actuators for quick open/close cycles.


Key Advantages

Cost-Effective: Lower material and installation costs compared to lug or flanged valves.
Easy Installation: No nuts or threaded inserts—simply bolt between flanges.
Lightweight: Reduces structural load on pipelines.
Versatile Media Handling: Suitable for water, air, steam, and mild chemicals.
Minimal Maintenance: Simple design with fewer wear-prone components.


Applications

Wafer centerline butterfly valves are ideal for:

  • Water Supply Systems: Pump stations, pipelines, and irrigation networks.

  • HVAC: Air handling units, chilled water systems, and energy management.

  • Fire Protection: Sprinkler systems and emergency shutoff lines.

  • Chemical Processing: Non-corrosive fluid transfer and dosing.

  • Food & Beverage: Sanitary processes with FDA-compliant seals.

  • Marine & Shipbuilding: Compact solutions for onboard piping.

Maintenance Guidelines

  1. Regular Inspections: Check disc alignment, seat integrity, and flange bolts for tightness.

  2. Cleaning: Flush the valve body to remove debris that may scratch the disc or seat.

  3. Lubrication: Apply silicone-based grease to the stem every 6–12 months.

  4. Seal Replacement: Replace elastomer seats every 3–5 years, depending on media compatibility.

  5. Flange Inspection: Ensure gaskets are undamaged to prevent leaks.
