Product Description

Product Specifications
Valve Type: Wafer butterfly valve Structure: Concentric
Standard: EN593 Workmanship: Investment casting
Sealing Direction: Bidirectional Sealing Grade: Zero leakage
Temperature: -20°C < T < 120°C Operation: Handle / Lever
Characteristics
The inner cavity of the valve body and the surface of the butterfly plate are fully covered with polytetrafluoroethylene (PTFE) material, which has extremely strong chemical stability and can withstand most strong corrosive media including concentrated sulfuric acid, hydrochloric acid, and nitric acid. The temperature resistance range can reach -196°C to 200°C.
PTFE Lined Butterfly Valve
Key Advantages
Small Opening and Closing Torque

The friction coefficient of PTFE material is extremely low (0.02–0.10), and the valve seat has a self-lubricating effect, greatly reducing resistance. achieve rapid opening and closing with lower energy consumption.

Clean and Pollution-Free

PTFE has strong chemical inertness, does not adsorb media, and meets FDA/GMP standards. Ideal for food, pharmaceutical, and electronic semiconductor industries.

Wide Temperature Range

Standard operating conditions range from -20°C to 120°C, while the lining can adapt to cryogenic and medium temperature corrosive fluids.

Packaging
Standard export wooden case packaging ensures the safety and integrity of the valves during international transportation.
Standard export wooden case
Application Scenarios
Widely used in corrosive or high-purity medium conveying systems in various industries such as chemical, pharmaceutical, food and beverage, power, and environmental protection.

Frequently Asked Questions
What is a PTFE-lined wafer butterfly valve?
A PTFE-lined wafer butterfly valve is a concentric valve where the internal cavity and butterfly plate are fully coated with PTFE, providing exceptional chemical resistance and zero-leakage sealing.
What temperature range can this valve handle?
Under standard conditions, it handles -20°C to 120°C. The PTFE lining itself is capable of withstanding -196°C to 200°C for specialized applications.
Which industries are these valves suitable for?
They are widely used in chemical processing, pharmaceuticals, food and beverage, power generation, and semiconductor manufacturing where corrosive or high-purity fluids are managed.
Does this valve comply with safety standards?
Yes, PTFE is chemically inert and meets FDA and GMP standards, making it ideal for sterile media transportation in regulated industries.
What actuation options are available?
The valve supports manual handle/lever operation, as well as pneumatic or electric actuators for automated systems.
How is the valve packaged for export?
All valves are shipped in standard export wooden cases to ensure maximum protection during international transit and storage.
