air actuated valves that utilise a compressed air supply to operate.

Flow regulating valves with manual or electric modulating 4-20mA control.

2 ports (inlet/outlet) with 2 positions (Open/Closed) - valve stays closed (Failsafe) requires power to open

2 ports (inlet/outlet) with 2 positions (Open/Closed) - valve stays open (Failsafe) requires power to close

2 ports (inlet/outlet) with 2 positions (Open/Closed) - power or air one side to move - power or air opposite side to return.

Valve requires power to open and power to close, no power valves stays in position.

Valve opens proportionally according to signal input, either 4-20mA, 0-10v or 0-5 volt. Example 4mA valve closed, 8mA 25% open, 12mA 50% open, 18mA 75% open and 20mA fully open.

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

Can control flow in both directions

Flow regulation to control the amount of flow.

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

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

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

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

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.
