Stainless Steel Wafer Butterfly Valve Stainless Steel Disc, FKM (Viton) Liner

This premium wafer-pattern butterfly valve is engineered for high-performance flow control in systems where chemical resistance, durability, and precision are essential. Featuring a stainless steel body and disc paired with an FKM (Viton®) liner, this valve is ideal for handling aggressive media, elevated temperatures, and future automation upgrades.

Technical Data:

• Body Material: 316 stainless steel (or equivalent CF8M), offering exceptional resistance to corrosion and mechanical stress
• Disc Material: Stainless steel disc for strong shut-off performance and long-term durability
• Seat / Liner Material: FKM (Viton®) a high-performance fluoroelastomer with outstanding chemical resistance and thermal stability
• Connection Type: Wafer-pattern designed to mount between standard flanges PN6, PN10, PN16, ANSI 150, Table D and/or Table E Flanges
• Pressure Rating: PN16 suitable for pressures up to 16 bar
• Temperature Range: 10°C to +140°C (some versions may tolerate up to +150°C depending on liner specification)
• Mounting Interface: ISO 5211 top pad for direct mounting of gearboxes or actuators
• Available Sizes: Commonly offered from DN50 (2") up to DN200 (8")
• Flow Profile: Full-bore design for low pressure drop and smooth flow characteristics

Key Features:

• Robust Stainless Steel Construction: Delivers exceptional strength and corrosion resistance, even in demanding chemical or marine environments
• FKM Liner Advantage: The Viton liner provides superior sealing, resists a wide range of aggressive fluids, and maintains flexibility and integrity at elevated temperatures
• Compact Wafer Design: Allows for easy installation between flanges, minimizing footprint while maintaining stability
• Automation-Ready: ISO 5211 interface enables quick transition from manual to electric or pneumatic actuation without modification
• Smooth Operation: Low operating torque and full-bore disc contribute to efficient system performance and long service life
• Low Maintenance: Durable materials and reliable sealing reduce the need for frequent servicing or part replacement

Typical Applications:

• Chemical processing lines handling solvents, acids, or oils
• Water treatment systems, including chlorinated and high-purity applications
• HVAC systems where high temperature and aggressive water treatments are used
• Industrial manufacturing processes requiring corrosion-resistant flow control
• Marine and offshore systems exposed to saltwater and harsh operating conditions

Summary:
This stainless steel wafer butterfly valve with an FKM (Viton®) liner delivers precision, durability, and versatility in a compact, high-performance package. Whether managing aggressive chemicals, elevated temperatures, or fluid systems requiring tight shut-off and future automation potential, this valve is a dependable and efficient solution for modern engineered systems.
