BFHV01-TA01-Operation and Maintenance Manual DOWNLOAD

1. Robust Body Material
The valve body is made of **GGG40/500-7 Ductile Iron**, offering excellent strength, toughness, and impact resistance, guaranteeing long-term, stable performance within the pipeline system.
2. Superior Corrosion-Resistant Discs
The dual discs are manufactured from **CF8M (AISI 316 Stainless Steel)**, which provides superior corrosion resistance against chlorides and a wide range of chemicals compared to 304 stainless steel, significantly extending service life in demanding conditions.
3. Compact & Efficient Wafer Design
The wafer-style construction saves space and weight. It installs directly between pipeline flanges using through-bolts, eliminating the need for extra flange nuts and significantly reducing installation time and cost.
4. Reliable Backflow Prevention
The spring-assisted dual-plate design ensures quick response and tight closure, effectively preventing water hammer, reducing system shock and noise, and protecting upstream equipment.

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.
