Operation

Direct Acting

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

Pressure Assisted

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

Options required

Anti Water Hammer

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

Bi-Directional Flow

Can control flow in both directions

Manual Override

A facility to manually move the valve into the fully actuated position via a button, lever or key.

Mounting Bracket

Valve has the facility to be supplied with a bracket for mounting and securing.

Mounting Holes

Supplied with additional threaded holes typically in the base, typically for securing to a baseplate.

Position Feedback Closed

The valve is equipped with an additional volt free electrical switch that is triggered when the valve is mechanically closed.

Position Feedback Open+Closed

The valve is equipped with two additional volt free electrical switches that are triggered when the valve is mechanically closed or open position.

Position indication Visual

The valve is equipped with clear cover or dome under which an arrow or flag can be seen to confirm either the open and or closed position of the valve.
