Bi-Directional Flow0

Can control flow in both directions

Degreased0

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

Flow Control0

Flow regulation to control the amount of flow.

Manifold0

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

Manual Control0

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

Manual Override0

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

Mounting Bracket0

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

Mounting Holes0

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

Outlet - right angle0

Position Feedback Closed0

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

Position Feedback Open+Closed0

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

Position proximity switch - Open0

The valve is equipped with an additional volt free electrical switch that is triggered as the valve reaches the open position.

Position indication Visual 0

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.

Y Pattern0

A Y-pattern valve is a valve with a Y-shaped body design, typically used for high-pressure applications to reduce pressure drop and turbulence, often found in steam systems.
