      These diaphragm valves help to allow precise control via a manual handwheel with a built-in locking mechanism and position indicator. They are suitable for chemical feeding and slurry flow control. They also close by means of a flexible diaphragm attached to a compressor, which can be actuated manually or automatically. When the compressor is lowered by the valve stem, the diaphragm seals and cuts off flow.

      These diaphragm valves close by means of a flexible diaphragm attached to a compressor, which can be actuated manually or automatically.

The diaphragm is 1-pc. machined modified PTFE for increased flexibility and life, and features a PVDF coated stainless steel spring to resist corrosion. The tongue-and-groove seat and diaphragm help to provide positive through-flow shut off and diaphragm-to-body seal. Suitable for high-purity semiconductor applications and in wet or gaseous corrosive environments.
