Manual and Actuated Valves

Our diaphragm valve range is particularly suitable for regulation or on-off operations with dirty or abrasive fluids. Offering significantly increased flow rates, due to the optimised design of the valve body, the Dialock® valve is the most linear diaphragm valve available.

The valve is operated by use of a diaphragm rather than a ball, this makes the valve highly suited to applications that contain sediment or solids in suspension which can pass through the valve easily.
