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.

Bi-Directional Flow0

Can control flow in both directions

Flow Control0

Flow regulation to control the amount of flow.

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

The outlet port is at right angles to inlet port, ideal for space efficiency.

Panel Mount0

Valve is designed to be mounted and secured into an instrument panel

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.
