Saunders non-lined diaphragm valves are robust, cost-effective flow control solutions designed for general industrial applications where full chemical lining is not required. These valves retain the proven diaphragm valve principle while utilising unlined metallic body construction for strength and versatility. The flexible diaphragm provides a tight, leak-free seal by isolating the process fluid from the valve’s operating mechanism, ensuring reliable performance and minimal contamination risk. Without an internal lining, the valve offers a simpler design, making it well suited for less aggressive media, utility services and applications where durability and ease of maintenance are key priorities.
