Product Overview

Tianjin Worlds Valve Co., Ltd. offers a high-performance lug butterfly valve with a two-piece body, an aluminum bronze disc, a PTFE seat, and a hand lever, engineered for reliable on/off isolation in pipelines where corrosion resistance, chemical compatibility, and low maintenance are critical. The lug body enables dead-end service at full rated pressure, while the two-piece construction allows easy disassembly for inspection or seat replacement without pipeline removal. The C95400 aluminum bronze disc provides exceptional resistance to seawater, brackish water, and aggressive chemicals, and the PTFE seat delivers low-friction, chemically inert sealing from -35°C to +200°C. The hand lever offers simple 90° operation with visual position indication and a locking plate for basic flow regulation. Available DN50-DN1200, PN10/PN16/Class 150, suitable for marine, chemical, desalination, and industrial applications. As a direct ISO 9001 certified OEM/ODM manufacturer, we produce valves to customer specifications with CE, UKCA, WRAS, and ACS certifications available upon request.

Key Features & Advantages：

1. Aluminum Bronze Disc – Superior Corrosion Resistance for Seawater & Aggressive Media

• C95400 aluminum bronze offers outstanding resistance to corrosion, pitting, and erosion in seawater, brackish water, and marine environments.

• High strength and impact resistance ensure reliable operation under frequent cycling.

• Anti-dezincification and erosion-resistant properties extend service life in aggressive conditions.

 

2. PTFE Seat – Chemical Inertness & Low Friction

• PTFE is inert to most acids, alkalis, solvents, and oxidizing agents, providing excellent chemical compatibility.

• Self-lubricating surface reduces operating torque and prevents media buildup.

• Temperature range: approximately -35°C to +200°C.

 

3. Two-Piece Body Construction – Easy Maintenance & Inspection

• The valve body can be disassembled without removing the valve from the pipeline.

• Simplifies seat replacement, disc inspection, and cleaning.

• Reduces downtime and maintenance costs.

 

4. Lug Body – Dead-End Service Capability

• Threaded lug inserts allow direct bolting to a single flange for end-of-line isolation.

• Enables downstream pipeline removal without affecting the upstream side.

• Compatible with EN 1092, ANSI B16.5, and AS2129 flanges.

 

5. Hand Lever Operation – Simple & Intuitive Control

• 90° quarter-turn operation; lever position clearly indicates open/closed.

• Locking plate allows basic flow regulation at intermediate angles.

• Low operating torque; suitable for frequent manual cycling.

 

6. Bi-Directional Tight Shut-Off & Low Pressure Drop

• 100% bi-directional tight shut-off with installation without restriction in direction of flow.

• Streamlined disc profile minimizes turbulence and pressure loss.

• High Kv/Cv values contribute to reduced energy costs.

 

7. Fully Customizable OEM/ODM Solution

• Disc materials: Aluminum bronze (standard), CF8, CF8M, duplex, super duplex...

• Seat materials: PTFE (standard), EPDM, NBR, Viton...
