Function

2/2 Normally Closed

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

2/2 Normally Open

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

2/2 Latching

2 ports (inlet/outlet) with 2 positions (Open/Closed) - short power pulse valve stays open - reverse power pulse valve stays closed

2/2 Double Acting

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

Power Open/Power Close

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

Proportional / Modulating

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.

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

Flow Control

Flow regulation to control the amount of flow.

Manual Override

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

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.

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.
