Product Features
2/2 Way Normally Closed Control
The 2L(US) Series uses a two-port, two-position structure for automatic on-off control. The valve remains closed when the coil is de-energized and opens after the correct electrical signal and required pressure differential are applied.
Designed for High-Temperature Steam Service
With a brass body and PTFE sealing structure, the series can be selected for steam and hot-fluid applications with medium temperatures up to approximately 180°C. Actual temperature capability must be confirmed according to the coil, seal, pressure, and supplied model.
Pilot-Operated Piston Structure
The internal pilot piston design uses inlet pressure to assist the opening of the main flow passage. It supports larger port sizes and higher flow than many compact direct-acting valves but requires a minimum pressure differential for correct operation.
G3/8 to G2 Threaded Port Options
Available models cover common pipeline sizes from G3/8 to G2, allowing selection for heating equipment, steam pipelines, hot-water systems, cleaning machinery, and industrial process equipment.
PTFE Seal for Steam Applications
PTFE is commonly selected for high-temperature steam valve sealing because it provides better temperature resistance than standard general-purpose NBR seals. Medium chemistry, pressure, and operating temperature must still be checked before selection.
Multiple Coil Voltage Options
Common coil options include DC12V, DC24V, AC24V, AC110V, and AC220V. The selected coil voltage must match the power supply, frequency, connector, and continuous-duty requirements.
Applications
Industrial Steam Pipelines
Used for electrically controlled opening and closing of steam supply lines in heating, drying, cleaning, and process equipment.
Sterilization and Cleaning Equipment
Suitable for sterilizers, bottle-washing equipment, cleaning machines, and hot-water systems when pressure, temperature, material, and seal requirements match.
Commercial Laundry Equipment
Applied in steam-fed washing, ironing, pressing, and drying equipment requiring automatic steam switching.
Heating and Temperature-Control Systems
Used in boilers’ auxiliary circuits, heat exchangers, steam-heating equipment, hot-water circulation systems, and temperature-control machinery.
Food and Packaging Machinery
May be used in steam or hot-water auxiliary circuits for food-processing and packaging equipment after confirming hygiene, material, pressure, and temperature requirements.
Steam valves are commonly used in heating, washing, sterilizing, laundry, bottle-washing, and food-processing equipment; suitability still depends on each machine’s working pressure, temperature, and material requirements.

FAQ
What is the 2L(US) Series steam solenoid valve used for?
It is used for electrically controlled on-off switching of steam, hot water, air, water, and compatible fluids in industrial pipeline and process equipment.
Is the 2L(US) Series a 2/2 way valve?
Yes. It has two ports and two operating positions, providing a basic open-or-closed flow path.
Is the valve normally closed?
Yes. The commonly supplied 2L(US) configuration is normally closed. It remains closed without electrical power and opens when the coil is energized under the required operating conditions.
Can this valve operate with zero inlet pressure?
No. The standard 2L(US) valve uses a pilot-operated piston structure and requires a minimum pressure differential. It should not automatically be described as a zero-pressure or zero-differential valve.
What port sizes are available?
Common sizes include G3/8, G1/2, G3/4, G1, G1-1/4, G1-1/2, and G2. The thread standard should be confirmed before ordering.
Can the valve be used continuously at 180°C?
Some documented versions are rated for media temperatures up to 180°C. Continuous operation depends on the actual coil, seal, ambient temperature, pressure, installation, and duty cycle, so the exact supplied specification must be confirmed.
Can the valve control water, air, or oil?
Yes, compatible versions may be used for water, air, light oil, and other neutral fluids when viscosity, pressure, temperature, and PTFE compatibility meet the valve requirements.
What should be confirmed before ordering?
Confirm the model, port size, thread type, working medium, inlet and outlet pressure, minimum pressure differential, medium temperature, coil voltage, electrical frequency, connector type, installation direction, and order quantity.
Does HOMIPNEU support OEM and distributor orders?
Yes. HOMIPNEU supports OEM and ODM supply, bulk orders, private labeling, export packaging, voltage selection, and specification confirmation for 2L(US) Series steam solenoid valves.
