Tianjin Worlds Valve Delivers DI Lug Butterfly Valves with CF8M Disc

Introduction

Tianjin, China–Tianjin Worlds Valve Co., Ltd. recently completed the production of a new batch of high-performance Lug Butterfly Valves, specifically configured for demanding water and industrial applications. This recent production run highlights the company’s capability to deliver customized material solutions that meet strict international standards.

The featured product is a 6-inch (DN150) Lug Butterfly Valve, designed with a robust Ductile Iron (DI) body and a CF8M (AISI 316) stainless steel disc. This combination is specifically chosen to provide excellent structural strength while offering superior corrosion resistance against aggressive media.

To ensure safe and reliable operation, the valve is equipped with a WRAS-approved EPDM seat. This certification makes the valve highly suitable for potable water supply and wastewater treatment systems. The internal SS410 stainless steel stem provides the necessary high mechanical strength and wear resistance to handle the torque required for daily operations, paired with a manual lever handle for straightforward flow control.

Key Specifications:

Size: 6 Inch (DN150)

Pressure Rating: PN16 (16 Bar)

Body: Ductile Iron (DI)

Disc: CF8M Stainless Steel

Seat: WRAS Approved EPDM

Stem: SS410 Stainless Steel

Operation: Manual Lever Handle

Marking: CE 0343 (LRQA Notified Body)

One of the primary advantages of the Lug-style design is its ability to support dead-end service. This allows maintenance crews to isolate and remove the downstream piping without depressurizing the entire system, significantly reducing downtime.

Full Customization and Manufacturing Capability

While this specific order features a 6-inch configuration, Tianjin Worlds Valve manufactures Lug butterfly valves in sizes ranging from DN50 to DN2000.

"We understand that no two projects have the same requirements," said the engineering team at Tianjin Worlds Valve. "Therefore, our material configurations are not fixed. Customers can fully customize the body, disc, stem, and seat materials to match their specific media, temperature, and pressure conditions."

As a direct OEM/ODM manufacturer with over 19 years of export experience, the company operates under an ISO 9001:2015 quality management system certified by LRQA. Every valve is permanently marked with the CE 0343 logo (Notified Body 0343), proving full compliance with the EU Pressure Equipment Directive (PED 2014/68/EU Module H). The facility also holds UKCA certification, alongside WRAS and ACS approvals for drinking water applications.

This batch of valves has successfully passed the 100% hydrostatic and seat leakage tests and is ready for shipment.
