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
