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 article introduces a 10-inch PTFE lined lug butterfly valve featuring a ductile iron body, a PTFE seat, and a PTFE-encapsulated ductile iron disc–rated at Class 150. With full PTFE encapsulation ensuring zero metal contact and bubble-tight sealing, this valve is ideal for aggressive chemical, pharmaceutical, and semiconductor applications. As an LRQA-certified ISO 9001:2015 OEM/ODM manufacturer with over 19 years of export experience, Tianjin Worlds Valve Co., Ltd. offers fully customizable solutions to meet specific project requirements.
Double flanged butterfly valve for heavy-duty systems: ductile iron body, CF8M disc, vulcanized EPDM seat for zero leakage and metal isolation. Electric actuator (on-off/modulating with feedback), PN16, fully customizable. Certified ISO 9001, CE, UKCA, WRAS, ACS; 100% pressure tested with traceable certs. Factory direct, 15–40 days lead time.
Wafer butterfly valve with ductile iron body, CF8 disc, and EPDM seat. Reliable bubble-tight shut-off for water, HVAC, and industrial systems. OEM/ODM available.
This guide covers everything you need to know about lug butterfly valves—why they outperform wafer valves in dead-end service and isolated maintenance, how material selection (ductile iron, stainless steel, carbon steel) impacts performance, and key installation and maintenance best practices. Learn the lug vs wafer comparison, common selection mistakes to avoid, and how to choose the right body material, seat, and actuator for water treatment, chemical processing, oil & gas, and HVAC applications. Backed by ISO 9001 certification and full OEM customization with 19+ years of export experience.
This guide covers PTFE lined butterfly valve operation, components, and benefits of virgin PTFE with a 3‑4 mm thick liner (50% thicker than standard). The inert PTFE surface provides chemical resistance (pH 0‑14), purity, and bubble‑tight sealing from ‑40°C to 200°C. Applications include chemical, pharmaceutical, food, water, oil & gas, and semiconductor industries. It compares linings, offers a selection guide, and details quality tests (30KV spark, hydrostatic, traceability). From Tianjin Worlds Valve (19+ years), the article highlights virgin PTFE, thick liner, and certifications (ISO, CE, UKCA, etc.) ensuring reliable, low‑maintenance, cost‑effective control for aggressive and high‑purity fluids.
