Aluminum Bronze Disc Dual Plate Wafer Check Valve: Corrosion-Resistant, Zero-Leakage Protection for Marine & Aggressive Media Systems
Tianjin Worlds Valve Co., Ltd. – ISO 9001, CE, UKCA & WRAS Certified Manufacturer
BFHV02-TA01-Operation and Maintenance Manual DOWNLOAD

1. Superior Corrosion Resistance: The aluminum bronze discs and often-matched bronze/SS trim provide outstanding performance in marine environments, cooling seawater systems, and chemical media where cast iron or standard stainless steel may fail.
2. Compact & Lightweight Wafer Design: The wafer-style body fits directly between pipeline flanges without extra flange kits, saving significant weight, space, and installation cost compared to swing check valves.
3. Low Pressure Drop, High Flow Efficiency: The dual plates retract fully into the valve body, creating an unobstructed flow path that minimizes energy loss and optimizes system efficiency.
4. Rapid Response & Water Hammer Mitigation: Lightweight discs and precise spring assistance ensure quick closing, reducing the risk of damaging pressure surges (water hammer).
5. Bidirectional Sealing (Optional): Many models can be specified for bidirectional sealing, protecting systems where reverse flow may come from either direction.
6. Low Maintenance & Long Service Life: Robust construction, corrosion-resistant materials, and no complex linkages result in a valve that requires minimal attention even in harsh conditions.
7. Quality Assurance & Compliance
ISO 9001 Certified Manufacturing: Ensures consistent quality control throughout production process
International Certifications: CE, UKCA, and WRAS approvals guarantee compliance with global market requirements
Material Traceability: Full documentation and material certifications available for quality verification

We are a certified manufacturer with deep expertise in metallurgy and valve design for aggressive services. Every valve is rigorously tested. We offer full customization (materials, pressures, sizes, coatings) to meet your exact project specifications and certification requirements (CE, WRAS, UKCA, DNV, etc.).
This technical article compares EPDM, NBR, and PTFE valve seat materials for industrial applications. It outlines the advantages of elastomers (EPDM for water, NBR for oils) and the necessity of PTFE for aggressive chemicals and temperatures up to 200°C. Crucially, it clarifies the engineering difference between a "PTFE seated valve" and a "PTFE fully lined valve." The guide includes a material selection matrix and concludes with Tianjin Worlds Valve's manufacturing capabilities and CE/PED, WRAS, and ACS certifications.
This article introduces an 8-inch PTFE lined butterfly valve with a double flanged, two-piece split body design. The valve features a fully PTFE lined body bore and flange faces, a PTFE encapsulated stainless steel disc, and a PTFE seat—providing complete metal isolation and excellent corrosion resistance for chemical, pharmaceutical, petrochemical, and seawater applications. The split body allows in-line maintenance and field-replaceable PTFE components. As an LRQA-certified ISO 9001:2015 OEM/ODM manufacturer with over 15 years of export experience, Tianjin Worlds Valve Co., Ltd. offers fully customizable solutions to meet specific project requirements.
This article compares wafer and double flanged butterfly valves to help engineers and buyers select the right connection type. It details the advantages of wafer valves (compact, cost-effective) and double flanged valves (rigid, dead-end service, large-diameter applications), and explains the in-between option of lug valves. It also highlights the importance of selecting the right seat material (like PTFE for corrosive media). Tianjin Worlds Valve is introduced as a certified OEM/ODM manufacturer of all three body styles.
This article introduces a DN1600 double offset butterfly valve with a ductile iron (EN-GJS-500-7) body and disc, an SS420 stem, an SS316 metal seat, and an electric actuator with worm gear. It explains the double offset working principle, why the design suits large-diameter service, how each material contributes to strength, wear resistance, and corrosion resistance, and where this configuration is typically used. It also covers installation and maintenance considerations for large valves. Tianjin Worlds Valve Co., Ltd. is presented as an LRQA-certified ISO 9001:2015 OEM/ODM manufacturer with over 19 years of export experience, offering customizable large-diameter butterfly valve solutions.
This troubleshooting guide covers seven common butterfly valve problems — external flange leakage, internal seat leakage, stem packing leaks, incomplete operation, high operating torque, body corrosion, and actuator failures — along with root causes and practical field solutions. It includes a preventive maintenance schedule and a repair-or-replace decision guide. As an LRQA-certified ISO 9001:2015 OEM/ODM manufacturer, Tianjin Worlds Valve Co., Ltd. supplies butterfly valves in multiple configurations and seat materials to support reliable long-term operation.
