Operation

Direct Acting0

Directly controls flow without external pressure assistance operates from vacuum upwards.

Pressure Assisted0

Operate via pilot pressure control and require a minimum pressure difference between inlet and outlet from 0.5 Bar.

Options required

Anti Water Hammer0

Prevents or reduces water hammer caused by sudden changes in fast moving fluid flow.

Manual Control0

Valves that require manual input to operate such as lever, button or switch
