Operation

Assisted Lift

Assisted lift solenoid valve assists in opening against pressure, ensuring reliable operation from vacuum to medium pressure systems.

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

Degreased

Oil and grease removed typically for oxygen or paint spray use.

Manual Override

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

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.

Shading Ring - Silver

The copper shading ring in the solenoid tube has been replaced with silver. Typically used for RO water and aggressive media applications.

Shading Ring - without

The copper shading ring in the solenoid tube has been removed, for DC voltages only and typically for aggressive media applications.
