A patented locking hand wheel allows the valve to be adjusted and locked in over 300 positions – said to be more than any other diaphragm valve on the market – offering flexibility to the end user.

Offering significantly increased flow rates, due to the optimised design of the valve body, the Durapipe Dialock valve is claimed to be the most linear diaphragm valve available, with the new internal geometry allowing a substantial increase in flow coefficient values and a reduction in pressure loss.
