Description

1/2 BSP Normally Open Brass Solenoid Valve – UW15NO


Normally Open Zero-Rated Solenoid Valve

The UW15NO is a 2/2 way normally open brass solenoid valve designed for air, water, light oils, vacuum and compatible gases and fluids.

In its normal de-energised state the valve is open, allowing media to flow. Energising the solenoid closes the valve.
The assisted-lift design provides zero-rated operation from 0 Bar, making the valve suitable for applications where pressure differential cannot always be guaranteed.

Duty Rating: 90%
Voltages: 24V DC, 24V AC with rectified connector, 110V AC or 230V AC
DIN connector included.

Normally Open Operation

The valve remains open without electrical power and closes when the coil is energised.
This makes it suitable for applications requiring a fail-open valve arrangement, where flow should continue in the event of electrical power loss.
Typical Applications
Suitable for compressed air systems, water control, light oils, vacuum equipment, machinery, process systems and general industrial fluid control where normally open or fail-open operation is required.

Clearance – Replaced by PU22004AN

The UW15NO has been replaced by the upgraded PU22004AN 1/2" normally open solenoid valve and is available only while remaining stocks last.
For new installations and ongoing availability, we recommend the PU22004AN replacement.
