3 inch Threaded Butterfly Valve

Sanitary threaded butterfly valve for easy process control

Thread Butterfly Valve comes with a pull-trigger locking mechanism to control process flow. This product comes standard in 304, 316L stainless steel alloy.

Dual Threaded Designs

Threaded Body Butterfly Valve: Direct NPT/BSPT pipe threading cuts installation time by 50% vs. flanged valves – ideal for tight spaces in marine ballast systems or HVAC ductwork.

Threaded Lug Butterfly Valve: 4-way bolt holes enable valve removal without pipeline disassembly – perfect for chemical dosing lines requiring frequent maintenance.

Military-Grade Stainless Steel

304/316 SS disc + EPDM seals withstand:

➔ Saltwater corrosion (tested to ASTM B117 salt spray standards)

➔ High-temperature steam (-22°F to 302°F / -30°C to 150°C)

➔ Abrasive media like slurries and powders (Ra 1.6μm surface finish)

Zero-Leakage Assurance

Bidirectional sealing meets ISO 5208 Class A (≤0.1% leakage) with optional fire-safe API 607 certification for oil/gas applications.

Applications

Water Treatment Plants: Rapid shutoff in backwash pipelines (3-second actuation)

Food & Beverage: CIP/SIP-compatible design for dairy processing (3-A Sanitary optional)

Shipbuilding: Corrosion-resistant solution for seawater cooling systems

Industrial Gas: ATEX-certified models for compressed air/N2 lines

Case Study
“In a Singapore marine terminal, EAGLE’s 3” threaded lug valves reduced maintenance downtime by 70% compared to wafer-style valves. The 316 SS construction showed zero corrosion after 2 years in salt spray environments.”
