Description

1½ BSP Bronze Normally Open Solenoid Valve – UW40NO


Normally Open Zero-Rated Solenoid Valve

The UW40NO is a 2/2 way normally open solenoid valve designed for high-flow control of air, water, light oils, vacuum and compatible non-corrosive fluids.
Its assisted-lift design provides zero-rated operation from 0 Bar, making it suitable for applications where little or no pressure differential is available.
The large 1½ BSP bronze valve body incorporates a 40mm orifice for high-flow industrial fluid-control applications.

Normally Open Operation

Function: 2/2 way normally open
Operation: Assisted lift / zero rated
Normal Position: Open without electrical power
Energised Position: Closed
Minimum Differential Pressure: 0 Bar
Maximum Differential Pressure AC: 7 Bar
Maximum Differential Pressure DC: 5 Bar
Maximum Working Pressure: 10 Bar

Port & Flow

Port Size: 1½ BSP
Optional Threads: BSPT or NPT
Orifice: 40mm
Kv Flow Factor: 400.4 L/min

Construction

Body: Cast bronze
Internal Components: Stainless steel
Standard Seals: NBR
Optional Seals: FKM or Silicone
The UW range uses forged brass bodies up to 1", while the larger 1¼"–2" valves, including the UW40NO, use cast bronze bodies.

Media & Temperature

Suitable Media: Air, water, light oils, vacuum 10⁻³ and compatible non-corrosive gases and fluids
Maximum Viscosity: 20 cSt
NBR Maximum Media Temperature: +80°C
FKM Maximum Media Temperature: +120°C
Silicone Maximum Media Temperature: +130°C
Ambient Temperature: -5°C to +60°C

Coil & Electrical

Coil: Moulded resin
Duty Rating: 90%
Insulation: Class F, 155°C
Electrical Connection: DIN 43650
Protection: IP65 with connector
Available Voltages: 24V DC, 110V AC and 230V AC

Installation

Mounting: Coil upright
The valve can be installed directly into suitable industrial pipework, with adequate upstream filtration recommended to protect the internal diaphragm and sealing components.

Typical Applications

Ideal for water systems, compressed air, tanks, process equipment, machinery, vacuum applications and general industrial fluid control where a normally open valve and operation from zero differential pressure are required.

Clearance – Replaced by RK40

The UW40NO has been replaced by the upgraded RK40 1½ BSP normally open solenoid valve and is available only while remaining stocks last.
For new installations and ongoing availability, select the RK40 replacement.
