Tianjin Worlds Valve Co., Ltd. introduces the Soft Seal EPDM Covered SS 2507 Disc Butterfly Valves with Wafer Type Design, specifically developed to handle the most challenging corrosive and abrasive media in seawater desalination, chemical processing, and offshore applications. Featuring a super duplex 2507 stainless steel disc with EPDM soft seal covering and compact wafer design, this valve delivers exceptional resistance to pitting, crevice corrosion, and erosion while ensuring bubble-tight sealing under PN16 pressures. Manufactured under ISO 9001 quality system with CE, UKCA, and WRAS certifications, it represents the optimal solution for demanding fluid control applications where reliability and longevity are paramount.
1. Super Duplex 2507 Stainless Steel Disc
Exceptional Corrosion Resistance: PREN ≥42 provides superior resistance to chloride-induced pitting and stress corrosion cracking
Mechanical Strength: Yield strength approximately 2 times that of standard 316L stainless steel
Abrasion Resistance: Excellent performance in slurry and particle-laden media with hardness up to 280 HB
2. EPDM Soft Seal Covering Technology
Complete Media Isolation: EPDM covering prevents direct contact between corrosive media and metal disc surface
Temperature Resilience: Maintains sealing integrity from -20°C to 120°C in various chemical environments
Shock Absorption: Resilient EPDM layer dampens water hammer effects and vibration
3. Wafer Type Compact Design
Space Optimization: 35% lighter and more compact than lug-type valves, ideal for space-constrained installations
Easy Installation: Fits between ANSI/DIN flanges without additional nuts or hardware
Cost Efficiency: Reduced material and installation costs compared to traditional valve designs
4. High-Performance Sealing System
Zero Leakage Assurance: Achieves EN 12266-1 Class A
Long Service Life: EPDM-to-body sealing ensures reliable performance for 60,000+ operating cycles
5. Operational Excellence
Low Torque Operation: Optimized disc profile reduces operating torque by 30% compared to conventional designs
Multiple Actuation: Compatible with manual lever, gear operator, or ISO 5211 standard actuators
Maintenance-Free: Self-lubricating bearings and corrosion-resistant components eliminate routine maintenance
Seawater Desalination: Reverse osmosis systems, intake and outfall lines
Chemical Processing: Concentrated acids, chlor-alkali, and aggressive chemical media
Offshore Oil & Gas: Seawater cooling, firewater systems, and ballast water control
Pulp & Paper: Chlorine dioxide, bleaching chemicals, and corrosive pulping liquors
Mining & Mineral Processing: Acid leaching, slurry handling, and tailing management
Power Generation: FGD systems, cooling water, and chemical dosing applications
Customizable seat and lining materials
Full compliance with international standards
OEM/ODM support with third-party certification support
Global supply capability with after-sales technical service
Specifically engineered for the most challenging corrosive and abrasive applications, this EPDM-covered super duplex 2507 disc butterfly valve combines advanced materials with practical wafer design for exceptional performance and reliability.
