2/2 Normally Open Solenoid Valves

2/2 normally open solenoid valves (NO) are failsafe open valves that require electrical power to close. These valves remain open when de-energised, making them ideal for applications where flow must continue during power loss.

Show Sub Categories

2/2 normally open zero rated valves are failsafe open and will work from vacuum up to their maximum working pressure

2/2 Normally Open - Zero Rated

2/2 normally open solenoid valves (Failsafe Open) are pressure assisted and require a minimum pressure differential, typically 0.5 Bar. Available in Brass, Stainless and Plastic.

Operation

Assisted Lift0

Assisted lift solenoid valve assists in opening against pressure, ensuring reliable operation from vacuum to medium pressure systems.

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

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 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.

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.

Shading Ring - Silver0

The copper shading ring in the solenoid tube has been replaced with silver. Typically used for RO water and aggressive media applications.

Shading Ring - without0

The copper shading ring in the solenoid tube has been removed, for DC voltages only and typically for aggressive media applications.
