Manual and Actuated Diaphragm Valves
Manual diaphragm valves are ideal for flow control by offering a variable and precise opening for controlling pressure drop through the valve. Diaphragm valves are also ideal for slurry service and offer positive closing.
Actuated diaphragm valves can offer features as adjustable opening, positioners for precise flow control, and electric relay of valve position.
