Product Features
2/2 Way Normally Closed Control
The 2S Series uses a two-port, two-position structure for basic on-off fluid control. In the normally closed configuration, the valve remains closed when the coil is not energized and opens after the correct electrical signal is applied.
Stainless Steel Valve Body
The stainless steel body is suitable for applications that require better corrosion resistance than a standard brass valve. SS304 and SS316 options may be selected according to the working medium and installation environment.
Wide Port Size Range
The series includes compact 1/8″ and 1/4″ models as well as larger 3/8″, 1/2″, 3/4″, 1″, 1-1/4″, 1-1/2″, and 2″ options. This allows selection according to pipeline size and required flow.
Suitable for Multiple Media
The valve can be selected for air, water, oil, gas, and compatible neutral fluids. Medium compatibility depends on the body material, seal material, temperature, viscosity, and operating pressure.
Multiple Seal Material Options
NBR is commonly used for general air, water, and oil service. EPDM may be selected for suitable water-related applications, while FKM/Viton is often chosen when higher temperature or improved chemical resistance is required.
OEM and Distributor Supply
HOMIPNEU supports voltage selection, thread confirmation, seal selection, private labeling, export packaging, bulk orders, and model matching for distributors and industrial equipment manufacturers.
Applications
Water Treatment and Pipeline Control
Used for automated water supply, drainage, filtration, cleaning equipment, cooling systems, and general water pipeline switching.
Compressed Air Systems
Suitable for compressed air pipelines, air supply equipment, testing systems, and industrial machines requiring electrical on-off air control.
Oil and Compatible Fluid Circuits
Applied to low-viscosity oil and compatible fluid systems after confirming viscosity, seal material, operating pressure, and temperature.
Industrial Gas Control
Can be used for compatible gases and inert gas applications when the valve material, seal, leakage requirement, and operating conditions are correctly selected.
Food, Cleaning, and Process Equipment
Stainless steel models are commonly considered for washing equipment, filling machinery, cleaning systems, process equipment, and installations where corrosion resistance is important.

FAQ
What is the 2S Series solenoid valve used for?
The 2S Series is used for electrical on-off control of air, water, oil, gas, and other compatible fluids in industrial pipelines and equipment.
Is the 2S Series a 2/2 way valve?
Yes. It has two ports and two operating positions and is commonly supplied as a normally closed valve.
What does normally closed mean?
Normally closed means the valve blocks flow when the coil is not energized. When the correct voltage is applied, the valve opens and allows the medium to pass.
Is every 2S model direct acting?
Small-orifice models are commonly direct acting, while larger-port models may use a direct-lift diaphragm structure. The exact operating structure should be confirmed by model.
Can the valve be used with water and oil?
Yes, when the selected seal material, body material, viscosity, pressure, and temperature are compatible with the medium.
Can the 2S Series be used for steam?
Steam suitability must be confirmed separately. Standard NBR versions should not automatically be described as steam valves; the seal, coil, temperature rating, and valve construction must match the steam conditions.
What should be confirmed before ordering?
Please confirm model, port size, thread type, body material, seal material, medium, operating pressure, temperature, coil voltage, flow requirement, and installation space.
Does HOMIPNEU support OEM and distributor orders?
Yes. HOMIPNEU supports OEM and ODM supply, bulk orders, private labeling, export packaging, and specification confirmation for 2S Series stainless steel solenoid valves.
