This stainless steel highperformance butterfly valve represents the next level in precision flow control, combining advanced materials and engineering for superior performance in demanding process applications. The combination of a stainless steel body and disc with a dual-seal seat system, featuring RPTFE and Inconel625, delivers unmatched durability, corrosion resistance, and high-temperature stability. Lever Operated 2" to 5", Gearbox Operated 6" to 12".

Technical Data:

• Body Material: Highgrade stainless steel (CF8M or A351316 equivalent), offering exceptional corrosion resistance, strength, and long-term service reliability
• Disc Material: Stainless steel, precision-balanced for low operating torque and consistent sealing performance under pressure
• Seat Design: Dualseal system with RPTFE (Reinforced Polytetrafluoroethylene) as the primary seat and an Inconel625 secondary backup seal for high-temperature and high-pressure resilience
• Connection Type: Lugged body pattern designed for PN16/25 2" to 4", PN16 5" to 12" flanged systems; allows oneside pipeline disassembly without valve removal
• Pressure Rating: Rated up to PN25, suitable for medium to highpressure process environments
• Temperature Range: Operates effectively from approximately -60°C to +230°C, depending on media type and pressure conditions
• Size Range: Available in a full range of standard sizes from DN50 (2) to DN300 (12) and beyond on request
• Mounting Interface: ISO5211 top mounting pad for simple integration with gear operators, electric actuators, or pneumatic systems
• Design Geometry: Doubleoffset configuration reduces disc-seat contact, minimising wear, torque requirements, and extending the life cycle

Key Features:

• DualSeal Seat Technology: The combination of RPTFE and Inconel625 offers a perfect balance of soft-seal tightness and metal-seal durability, ensuring leakfree operation even in extreme service conditions
• Stainless Steel Construction: Provides excellent resistance to corrosion and scaling, ideal for use in aggressive media, steam systems, and marine environments
• Lugged Body Advantage: Allows secure bolting alignment and facilitates maintenance or line isolation without full pipeline removal
• HighPerformance Under Pressure: Designed for highcycle operation and elevated temperature service while maintaining precise shutoff performance
• Low Torque Operation: The doubleoffset disc design and RPTFE seat ensure smooth rotation with minimal operating effort
• Automation Ready: ISO mounting compatibility enables straightforward transition from manual to automated actuation without modification

Typical Applications:

• Petrochemical and chemical processing systems requiring highintegrity shutoff in corrosive or hightemperature environments
• Steam distribution and power generation systems
• Marine and offshore installations exposed to saltwater or humidity
• Water treatment, desalination, and industrial utility pipelines
• Process systems where long-term reliability and easy maintenance are essential

Summary:

The Stainless Steel HighPerformance Lugged Butterfly Valve with an RPTFE/Inconel625 seat is a premium solution for modern industrial systems. Designed to perform under extreme conditions, it combines robust stainless steel construction with advanced dual-seal technology to ensure consistent, leakfree operation. Compact, corrosion-resistant, and automation-ready, its built for engineers who expect reliability, longevity, and precision from every component in their process line.
