When the coil is not energized, the valve remains closed; when power is applied, the valve opens to allow medium flow. **3/4 Port for Medium-Flow Pipeline Systems** With a 3/4″ port size and 20mm orifice, the 2S200-20G is suitable for medium-flow pipeline systems that need reliable electrical on/off control. **Stainless Steel Valve Body** The stainless steel body provides better corrosion resistance than standard brass body valves, making it suitable for air, water, oil, gas, and compatible neutral fluid applications where cleaner or more durable material is required. **Normally Closed Safety Function** The normally closed design helps shut off the pipeline automatically when power is removed. This is useful for systems where the default state needs to remain closed for safety or process control. **Direct Lift Diaphragm Structure** The direct lift diaphragm structure supports stable opening and closing performance in fluid control applications. It helps provide reliable sealing and consistent response during repeated operation. **Suitable for Air, Water, Oil and Gas Control** The 2S200-20G can be used for compatible air, water, oil, gas, and other neutral media under proper pressure, temperature, and seal material conditions. **Multiple Voltage Options Available** The 2S200-20G can be supplied with common voltage options such as DC12V, DC24V, AC24V, AC110V, and AC220V to match different automation control systems. **Practical Choice for Automated Fluid On/Off Control** The valve is suitable for equipment that requires electric signal control of pipeline flow, including water systems, gas lines, oil circuits, cleaning equipment, filling machines, and industrial automation equipment. ### Applications The 2S200-20G normally closed stainless steel solenoid valve is widely used in air pipelines, water supply systems, oil circuits, gas control lines, cleaning equipment, filling machines, food and beverage equipment, water treatment systems, laboratory devices, HVAC auxiliary systems, and general automation fluid control systems. It is especially suitable for applications where the pipeline medium needs to be opened or closed by an electrical signal. For pneumatic cylinder direction control, a 5/2 way pneumatic solenoid valve such as 4V210-08 or 4V310-10 is usually more suitable. ### Why Choose HOMIPNEU HOMIPNEU supplies solenoid valves, pneumatic valves, manual valves, cylinders, fittings, and air source treatment components for industrial automation and fluid control systems.

It is not a 5/2 way pneumatic cylinder directional valve. **Is 2S200-20G normally closed?** Yes. It is commonly used as a normally closed valve, meaning the valve stays closed when the coil is not energized and opens when power is applied. **What is the port size of 2S200-20G?** The standard port size is 3/4″, suitable for medium-flow fluid control pipelines. **What does the “G” mean in 2S200-20G?** The “G” usually refers to the thread or connection version. Final thread type should be confirmed according to the actual product marking and customer requirement. **Can 2S200-20G be used for water?** Yes. It can be used for water if the pressure, temperature, seal material, and fluid compatibility match the system requirements. **Can 2S200-20G be used for oil or gas?** Yes. It can be used for compatible oil and neutral gas applications, but final selection should confirm working pressure, temperature, seal material, and safety requirements. **What is the difference between 2S200-20G and ZCA-200-20?** Both are 3/4″ fluid control solenoid valves, but 2S200-20G uses a stainless steel body, while ZCA-200-20 is commonly supplied with a brass body. Stainless steel is usually selected when better corrosion resistance or cleaner material is required. ### OEM & ODM Support HOMIPNEU provides OEM & ODM support for 2S Series stainless steel solenoid valves, including voltage options, seal material options, thread options, labeling, packaging, and batch supply for automation equipment manufacturers, pneumatic distributors, maintenance users, and industrial fluid control system suppliers. ###
