Ultra High Purity Diaphragm Valve Market Surges in 2025: Demand Grows Across Semiconductor and Pharmaceutical Industries

AFKLOK Ultra High Purity Diaphragm Valve is a valve specifically designed for high-purity gas and liquid transmission. It uses an elastic diaphragm as a seal and has both manual and pneumatic opening methods. The valve opens and closes through the elastic deformation of the diaphragm, avoiding common metal contact and wear issues in traditional valves.

The main features include:
• High-Purity Material: Typically made of high-purity stainless steel (such as 316L) or special alloy materials, which have excellent corrosion resistance and low gas output rate.
• No Dead Angle Design: The internal structure is simple with no dead zones or hard-to-clean corners, preventing residue accumulation.

• Sealing performance: Diaphragm materials (such as PTFE or FKM) have strong chemical stability and can maintain good sealing in high-temperature and high-pressure environments.
• Quick Response: The opening and closing actions are swift, suitable for scenarios requiring quick control.

Technical Specifications
• Working pressure: Depending on the series model, the maximum working pressure for low-pressure models can reach 300psig (20bar), while for high-pressure models it can reach 4500psig (310 bar).
• Working temperature: The temperature range is typically -23°C to 65°C.

• Leakage rate: The internal and external leakage rates are extremely low, typically at 1×10-9 mbar·l/s.

• Surface Roughness: The inner surface roughness can reach Ra 0.13μm (5μin), ensuring high purity transmission.

• Flow coefficient: The Cv value is usually around 0.27, with a maximum reaching about 0.8.
• Connection methods and sizes: Common connection methods include BCR metal face seal, ferrule connectors, and welding interfaces. Sizes range from 1/4 to 1inch to choose from.

AFKLOK ultra-high purity diaphragm valves are widely used in the following fields:
• Semiconductor Manufacturing: Used for the transmission of high-purity gases and liquids to ensure process purity.
