Stainless Steel Solenoid Valves | 2-Way Electric, Food-Grade & Industrial

Shop 2-way stainless steel solenoid valves with female NPT ports in sizes from 1/4" to 2" NPT. Available in Normally Closed (NC) and Normally Open (NO) configurations with 12V DC, 24V DC, 24V AC, and 110V AC coil options, these electric valves are designed for demanding fluid control applications where corrosion resistance, durability, and reliable performance are important.

Our stainless steel solenoid valves feature a straight-through inline design and are suitable for food-grade, commercial, residential, and industrial fluid control systems. We maintain a large inventory with same-day shipping available on in-stock products.

If your application requires a full-port alternative instead of a 2-way solenoid valve, explore our Stainless Steel Ball Valves collection.

Why Choose Stainless Steel Solenoid Valves?

Stainless steel is a popular valve body material because it combines excellent corrosion resistance with long-term durability. The chromium contained in stainless steel naturally forms a protective oxide layer that helps protect the surface from corrosion and can self-heal if scratched.

Benefits include:

• Excellent corrosion resistance
• Higher strength than brass and plastic
• FDA-approved food-grade material properties
• Safe for drinking water applications
• Easy to clean and maintain
• Suitable for marine environments
• Better heat resistance than plastic valve bodies

These advantages make stainless steel an excellent choice for fluid control systems exposed to moisture, washdown environments, corrosive media, and demanding industrial conditions.

Common Applications

Stainless steel solenoid valves are commonly selected for applications requiring corrosion resistance and dependable automated flow control, including:

• Food processing
• Beverage systems
• Drinking water systems
• Chemical processing
• Marine applications
• Commercial plumbing
• Industrial automation
• Compressed air systems
• Steam systems
• Water treatment

Choosing the Right Stainless Steel Solenoid Valve

Selecting the proper valve begins with understanding your application requirements.

Media Compatibility

Stainless steel valves are well suited for demanding media, including:

• Hot water
• Steam
• Compressed air
• Weak acids
• Organic solvents
• Industrial glycol
• Gasoline
• Diesel fuel

Always verify media compatibility and seal material on the individual product page before ordering.

Normally Closed vs. Normally Open

Choose the valve position based on how your system normally operates.

Normally Closed (NC)

Normally Closed valves remain closed when power is removed and open when energized. They are commonly used where flow should remain off until commanded.

Normally Open (NO)

Normally Open valves allow flow when power is removed and close when energized. These valves are ideal when continuous flow is required during normal operation.

Selecting the valve position that matches your application's normal operating state can reduce unnecessary coil operation.

Select the Correct Coil Voltage

Match the valve coil to your available power source.

Pressure, Temperature & Flow Rate

Pressure ratings vary depending on valve size and media.

Always review the individual product specifications for:

• Maximum working pressure
• Minimum operating pressure
• Flow coefficient (Cv)
• Temperature limits

General-purpose stainless steel valves operate from 15°F to 250°F (-10°C to 120°C) using high-performance seals.

Stainless Steel Grades

Our electric solenoid valves are available in both 304 and 316 stainless steel.

304 Stainless Steel

304 stainless steel is commonly used for general food-grade applications, drinking water, compressed air, and many commercial fluid systems.

316 Stainless Steel

316 stainless steel contains molybdenum, providing additional resistance to marine environments, saltwater exposure, and more corrosive applications.

If your application does not involve highly corrosive environments, 304 stainless steel often provides an excellent balance of performance and value.

Frequently Asked Questions

Are stainless steel solenoid valves food-grade?

Yes. Stainless steel offers FDA-approved food-grade material properties and is easy to clean, sanitize, and maintain.

Can stainless steel solenoid valves be used with drinking water?

Yes. Stainless steel construction is lead-free and suitable for drinking water applications.

Will these valves work in gravity-fed systems?

Yes. Our semi-direct acting 2-way general-purpose stainless steel valves operate from 0 PSI, making them suitable for gravity-fed and other low-pressure applications.

What voltages are available?

Available coil voltages include:

• • • 12V DC
    • 24V DC
    • 24V AC
    • 110V AC

What is the difference between Normally Closed and Normally Open?

• Normally Closed valves remain closed until energized.
• Normally Open valves remain open until energized.

What temperature range do these valves support?

General-purpose stainless steel valves operate from 15°F to 250°F (-10°C to 120°C).

Which stainless steel grade should I choose?

304 stainless steel is commonly selected for general food-grade and commercial applications, while 316 stainless steel is preferred for marine environments and more corrosive media.

Need Help Choosing the Right Stainless Steel Solenoid Valve?

Choosing the right stainless steel solenoid valve depends on your media compatibility, stainless steel grade (304 or 316), valve size, normally closed (NC) or normally open (NO) configuration, operating pressure, coil voltage, and flow requirements. Whether you're replacing an existing valve, specifying components for food and beverage processing, designing OEM equipment, building an industrial automation system, or selecting a valve for corrosive environments, our team can help you choose the right stainless steel solenoid valve for your application.
