### 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.
