Tianjin Worlds Valve Co., Ltd. – ISO 9001, CE, UKCA & WRAS Certified Manufacturer
1. Robust Ductile Iron Construction for Long Service Life
Built to withstand demanding industrial environments.
High-Strength Material: The strainer body is cast from GGG40/500-7 Ductile Iron, offering excellent tensile strength, impact resistance, and durability compared to standard gray iron.
Corrosion Protection: A durable epoxy coating (standard 250μm) provides an additional barrier against atmospheric and media corrosion, extending service life in buried or exposed installations.
Pressure Integrity: Designed to handle pressure ratings up to PN16 or Class 150, ensuring reliable performance in standard industrial systems.
2. Y-Shaped Design for Efficient Filtration
Optimized for effective debris capture with minimal flow restriction.
Ample Debris Collection Capacity: The angled Y-shaped body provides a large collection chamber, reducing the frequency of cleaning intervals in systems with moderate particulate loads.
Low Pressure Drop: The streamlined flow path minimizes pressure loss across the strainer, contributing to overall system energy efficiency.
Universal Flow Direction: Suitable for installation in either horizontal or vertical pipelines, with flow direction indicated by arrow on the body.
3. Flanged Connections for Secure Installation
Engineered for permanent, leak-proof pipeline integration.
Standard Flange Drilling: Flanged ends are manufactured to international standards including EN 1092-2 PN10/PN16 or ANSI B16.1 Class 125, ensuring compatibility with existing piping systems.
Easy Bolt-Up Installation: Integral flanges allow for straightforward bolted connection using standard gaskets and fasteners, simplifying installation and reducing labor time.
Removable Cover Access: The flanged cover (or threaded plug depending on model) allows for quick screen removal without disturbing pipeline connections.
4. Stainless Steel Screen with Customizable Filtration
Tailored to match your specific system protection requirements.
Corrosion-Resistant Screen: Standard screen is manufactured from stainless steel (SS304) for long service life and resistance to corrosion in water and mild chemical services.
Multiple Perforation Options: Available with perforated plate or wire mesh screens in various mesh sizes (typically 1.0mm to 3.0mm perforations, or 20 to 100 mesh) to capture specific particulate sizes.
Easy Cleaning & Maintenance: The removable screen can be quickly extracted, cleaned, and reinstalled, minimizing system downtime during routine maintenance.
5. Versatile Material Options for Media Compatibility
Customizable to match your specific application requirements.
Alternative Body Materials: Carbon steel, stainless steel (CF8/CF8M), or other alloys available upon request for specialized media compatibility.
Seal Material Options: Standard gaskets in EPDM, NBR, or Viton to suit different temperature ranges and chemical exposures.
Blow-Down Connection: Optional threaded blow-down port available for continuous or semi-continuous debris purging without cover removal.

This concentric wafer butterfly valve features a ductile iron body, CF8 stainless steel disc, and PTFE seat. The PTFE seat provides outstanding chemical resistance, a wide temperature range (-35℃to +200℃), and low friction operation. The concentric design ensures symmetric sealing, low torque, and bi-directional flow capability. Available DN50-DN600, PN10/PN16/Class 150. Suitable for chemical dosing, water treatment, food processing, and high-purity applications. Disc and seat materials are fully customizable for more aggressive service conditions. Manufactured by Tianjin Worlds Valve Co., Ltd., an ISO 9001 certified OEM supplier.
This product introduces a two-shaft wafer butterfly valve featuring a ductile iron body, CF8 stainless steel disc, EPDM seat, and worm gear operator. The two-shaft design uses independent upper and lower stems, simplifying maintenance and reducing the risk of seizure. The worm gear provides effortless self-locking operation with visual position indication. Available DN50-DN600, PN10/PN16, suitable for water, HVAC, and general industrial services. Disc and seat materials are fully customizable for more aggressive media.
This wafer butterfly valve from Tianjin Worlds Valve Co., Ltd. combines a CF8 (ASTM A351 Grade CF8) stainless steel disc with an NBR rubber seat, built into a ductile iron (GGG40) wafer body. The standard NBR seat performs well in oil, fuel, aliphatic hydrocarbon, and mild chemical media. Beyond this baseline configuration, all major components are fully customizable: disc materials include CF8, CF8M, Duplex 2205, Super Duplex 2507, and Aluminum Bronze; seat materials include EPDM, Viton (FKM), and PTFE. The product covers DN50–DN3000, fits PN10/PN16/Class 150 pipelines, and conforms to ISO 5752 face-to-face dimensions. Suitable for water treatment, oil handling, HVAC, food processing, and general industrial services.
This product describes a lug butterfly valve featuring a CF8M (AISI 316) stainless steel body and disc, operated by a manual hand lever. The lug design allows dead-end-service – the valve can be installed at pipeline ends without a downstream flange. Available with replaceable seats (EPDM, NBR, FKM, PTFE) for various media.
