Options required

Bi-Directional Flow

Can control flow in both directions

Degreased

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

Manifold

A group of multiple valves together on one manifold, simple layout streamline control and space saving.

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.
