Characteristics

Four stage sealing structure is adopted, and the sealing surface is equipped with temperature resistant and anti-aging silicone rubber elastic gasket valve seat, which can completely achieve zero leakage of media. For example, the special transition curve at the connection between the shaft head and the butterfly plate circumference and the reasonable interference fit of the valve seat, as well as the use of elastic O-rings and rigid gaskets and elastic rubber pads at the shaft shoulder end face of the shaft head, all contribute to improving the sealing performance.
Product Characteristics

Key Advantages

1. Chemical Resistance PTFE hardly reacts with most chemicals and can resist corrosion from strong acids, bases, and organic solvents. Only molten alkali metals and certain fluorides can degrade it at high temperatures.
2. Temperature Range It can operate continuously at temperatures ranging from -10°C to 180°C, with a maximum short-term tolerance temperature of approximately 290°C–320°C.
3. Low Friction The friction coefficient is as low as 0.02–0.10, which can reduce the wear of moving parts and prevent the medium from adhering to the valve.
4. Non-Reactive PTFE does not absorb water or gas, and can remain stable and uncontaminated in humid environments.

Packing & Delivery

Standard export wooden case packaging for secure international transit.

Application Scenarios

Within the chemical industry, it serves as a standard component for production lines processing aggressive media such as sulfuric acid and chlor-alkali products. In the pharmaceutical sector, its GMP-compliant hygienic design renders it ideal for sterile medium transfer systems. For power plant flue gas desulfurization (FGD) systems, it also provides an effective solution to mitigate valve erosion and wear caused by limestone slurry.

Frequently Asked Questions

What is the temperature range of this wafer butterfly valve?
This wafer butterfly valve is designed to operate continuously within a temperature range of -20°C to 120°C, making it suitable for a wide variety of industrial fluid control applications.
What sealing standard does this valve achieve?
The valve achieves zero leakage sealing grade. It utilizes a four-stage sealing structure with temperature-resistant, anti-aging silicone rubber elastic gasket valve seats, ensuring complete leak-free performance in both directions.
Why is PTFE used in this butterfly valve?
PTFE is used for its outstanding chemical resistance, wide temperature tolerance (-10°C to 180°C), ultra-low friction coefficient, and non-reactive nature, ensuring reliability in highly corrosive environments.
In which industries can this wafer butterfly valve be applied?
It is widely used in the chemical industry (sulfuric acid/chlor-alkali), the pharmaceutical sector (sterile transfer), and power plant flue gas desulfurization (FGD) systems.
What standard does this valve comply with?
This valve complies with the EN593 standard and is manufactured using precision investment casting (lost-wax casting) for superior surface finish and consistent quality.
How is the valve packaged for international export?
The valve is packed in standard export wooden cases, specifically designed to protect the product during international shipping and ensure it arrives in perfect condition.
