DN150 Lug Butterfly Valve (ANSI)
DN150 (6") · Wafer / Lug / Flanged · ANSI Class 150 (PN20, ~20 bar)
Reguvale's DN150 Lug Butterfly Valve (ANSI) combines a compact body with industrial-grade seating and actuation options for reliable isolation and control duty.
Key Features
Bubble-Tight Shutoff
Soft EPDM/PTFE seat gives zero-leakage isolation for water, oil and chemical lines.
Compact & Lightweight
Wafer body saves weight and installation space versus gate or ball valves.
Anti-Blowout Stem
Stem shoulder and live-loaded packing prevent ejection under line pressure.
Actuator Ready
ISO 5211 top flange accepts pneumatic, electric actuators or gearbox.
Corrosion Resistant
Ductile-iron, WCB or stainless bodies cover most plant media.
Fire-Safe Option
Metal backup seat available for fire-safe duty on request.
