Tianjin Worlds Valve Co., Ltd.–Your Reliable Source for Durable, Cost-Effective Flow Control

Key Features & Advantages

1. CF8 Stainless Steel Body and Disc–Corrosion Resistant & Durable

• Both body and disc cast from CF8 (ASTM A351 Grade CF8 / AISI 304), the cast equivalent of wrought 304 stainless steel.

• Offers good corrosion resistance for water, mild chemicals, acids, alkalis, and neutral salt solutions.

• Provides high strength and durability for long-term industrial service.

 

2. PTFE Seat–Chemical Inertness & Low Friction

• PTFE is resistant to almost all acids, alkalis, solvents, and oxidizing agents.

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

• Temperature range: approximately -35℃ to +200℃.

 

3. U-Type Body Design–Optimized Flow & Superior Sealing

• U-shaped flow channel optimizes the fluid path, reducing pressure loss.

• Enables tighter seal when closed, suitable for applications requiring a high degree of sealing performance.

• Ideal for large flow and low energy consumption scenarios.

 

4. Worm Gear Operator with ISO 5211 Top Flange–Easy Actuation

• Worm gear provides smooth, high-torque manual control with self-locking mechanism.

• ISO 5211 top flange enables direct mounting of electric or pneumatic actuators without custom brackets.

• Supports future automation upgrades with minimal modification.

 

5. Wide Size Range–DN50 to DN1200

• Covers everything from small branch lines to large-diameter industrial systems.

• 28 inches (DN700) described; other sizes available upon request.

• Suitable for chemical processing, water treatment, petrochemical, and general industrial applications.
