1. Dual Fluoropolymer Defense
PTFE Seat: Resists 98% sulfuric/nitric acids and halogen gases (-20°C to 200°C).
PFA-Coated 316L SS Disc: 500µm thick coating prevents pitting/corrosion under ASTM G48 testing, with Ra≤0.4µm surface smoothness for particle-free flow.
2. Zero Contamination Guarantee
Full fluoropolymer barrier isolates media from metallic components.
3. High-Temperature & Abrasion Resilience
PFA coating withstands 260°C intermittent peaks.
30% higher abrasion resistance than uncoated discs in slurry services.
4. Bubble-Tight Sealing
PTFE-to-PFA contact achieves ISO 5208 Rate A shutoff at 1.5x PN16 pressure.
Fire-safe option: API 607 metal secondary seals.
5. Maintenance-Optimized Design
Wafer-style body with ISO 5211 pad enables 10-minute actuator swaps.
Self-aligning disc prevents galling after 20,000+ cycles (ISO 9001 validated).

This product introduces a wafer type PTFE butterfly valve with ductile iron body, SS316 mirror-polished disc, and PTFE seat. It offers excellent chemical resistance for strong acids, alkalis, solvents, and oxidizing media across DN50-DN600, pressure up to 16 bar, and temperature -35°C to 200°C. Fully customizable and ISO 5211 ready for actuator mounting.
This article introduces the double-offset flanged butterfly valve from Tianjin Worlds Valve Co., Ltd. The valve features DN400 size, Class 150 pressure rating, ductile iron body and disc, flanged end connections, and an ISO 5211 top flange for direct actuator mounting. It highlights the double-offset design for reduced friction and improved sealing, while emphasizing that specific performance data depends on seat material, coating, and operating conditions. The company operates an ISO 9001 certified manufacturing system and offers test reports, material certificates, and applicable certifications upon request.
The Two-Piece U Type Butterfly Valve with PTFE Seat and PFA-Wrapped CF8M Disc from Tianjin Worlds Valve Co., Ltd. represents a premium solution for severe corrosion applications where reliability, purity, and maintainability are critical. Its advanced material combination—PFA encapsulation over CF8M disc, PTFE seat, and all-CF8M body—provides exceptional protection against the most aggressive chemicals, while the two-piece construction simplifies maintenance and reduces downtime.
This guide explores butterfly valves in hydroelectric power plants, covering their role as turbine main inlet valves, penstock protection valves, and emergency shut-off devices. It highlights key design features—double-eccentric configuration, biplane disc, dry shaft, and replaceable seats—that deliver low operating torque, minimal head loss, and corrosion protection. Selection criteria include diameter (DN500 to DN5000+), pressure class (PN2.5 to PN25), flow velocity, actuation, and sealing type. Tianjin Worlds Valve provides ISO 9001 certified, custom-engineered butterfly valves with CE-PED, UKCA certification and proven global experience across 50+ countries.
This technical guide examines butterfly valve applications in commercial and industrial HVAC systems, focusing on chilled water distribution, condenser water loops, cooling tower bypass, and heating water isolation. The article covers material selection (epoxy-coated ductile iron, EPDM seats, stainless steel discs), actuation options (manual, electric, pneumatic with BMS integration). Tianjin Worlds Valve Co., Ltd. offers ISO 9001 certified, competitively priced butterfly valves engineered for HVAC service, with successful project delivery to over 50 countries worldwide.
