The VATTEN pneumatic UPVC double-acting diaphragm valve is distinguished by its unique diaphragm design. The diaphragm effectively separates the lower valve body chamber from the upper valve cover chamber, preventing the valve stem, valve disc, and other components above the diaphragm from coming into contact with the medium, thereby avoiding corrosion. This design eliminates the need for a traditional packing seal structure and entirely prevents medium leakage.
The diaphragm itself is made from rubber or plastic materials, providing excellent flexibility and sealing performance, ensuring the valve’s reliability and stability during operation. With the diaphragm’s superior sealing capability, the overall structure is simplified, minimizing potential maintenance issues that could arise from more complex sealing arrangements.

Corrosion-resistant valve body and diaphragm for durability.
No packing gland structure, enhancing reliability.
Elastic diaphragm throttle element for efficient flow control.
Smooth valve body flow path, reducing friction and ensuring optimal performance.
Low start-up force, high flow capacity.
Leak-proof design, preventing external leakage.
Fire and explosion resistant, ensuring safety.
Widely used in industrial automation systems for handling strong acids, strong alkalis, highly corrosive, high-viscosity fluids, particulate-containing media, fibrous substances, and toxic or contamination-sensitive substances.
We can design and develop according to the needs of our customers to meet the requirements of different clients.
