Diaphragm valves are linear control valves that use a flexible diaphragm to isolate flow media from the operating mechanism, providing corrosion resistance and zero leakage. We supply weir type diaphragm valves sourced from qualified Chinese factories, with rubber lined or PTFE lined bodies, manual and pneumatic actuation options. Ideal for chemical, pharmaceutical, food & beverage and wastewater applications, especially for corrosive, sanitary and particle-containing media.
