Plastic Solenoid Valves | 2-Way Electric, Lead-Free & Chemical Resistant

Shop 2-way plastic solenoid valves in Normally Closed (NC) and Normally Open (NO) configurations with 12V DC, 24V DC, 24V AC, and 120V AC coil options. Available in sizes from 1/8" to 2", these lightweight, corrosion-resistant valves provide reliable automatic flow control for water, air, potable water, filtration, irrigation, and other low-viscosity fluid applications.

Plastic solenoid valves offer an economical alternative to brass and stainless steel valves while delivering excellent corrosion resistance and dependable performance in residential, commercial, and industrial systems.

If your application requires a quarter-turn valve instead of a solenoid valve, browse our UPVC Plastic Ball Valves.

Why Choose Plastic Solenoid Valves?

Plastic solenoid valves are designed for applications where corrosion resistance, lightweight construction, and cost-effective performance are important.

Benefits include:

• Lightweight construction that reduces stress on piping systems
• Corrosion-resistant valve bodies
• Lead-free, non-toxic construction
• Suitable for potable water systems
• Lower cost than comparable brass or stainless steel valves
• Stainless steel internal components for durability
• EPDM diaphragm for dependable sealing
• Available in threaded and push-to-connect configurations

These features make plastic solenoid valves an excellent choice for water systems, filtration equipment, irrigation, beverage equipment, and many other automated fluid control applications.

Common Applications

Plastic solenoid valves are commonly used in:

• Water filtration systems
• Drinking water systems
• Ice makers
• Drinking fountains
• Reverse osmosis systems
• Irrigation systems
• Hydroponics
• Commercial beverage equipment
• Residential plumbing
• Air and low-viscosity fluid systems

Material Construction

Our plastic solenoid valves are manufactured using durable engineering plastics, including:

• Polypropylene (PP)
• Polyoxymethylene (POM / Acetal)
• Nylon 66

Each product page identifies the exact body material used for that valve.

Internal moving components, including the plunger, spring, and orifice tube, are manufactured from corrosion-resistant stainless steel. EPDM diaphragms provide reliable sealing across a wide range of operating conditions.

Choosing the Right Plastic Solenoid Valve

Media Compatibility

Plastic solenoid valves are commonly used with:

• Water
• Potable water
• Air
• Low-viscosity fluids

Media compatibility depends on the valve body material, diaphragm material, temperature, and chemical concentration. Always review the specifications for the individual valve before ordering and confirm compatibility for your application.

Normally Closed vs Normally Open

Choose the valve position that best matches how your system normally operates.

Normally Closed (NC)

Normally Closed valves remain closed until electrical power is applied. They are the most common choice for automatic shutoff applications.

Normally Open (NO)

Normally Open valves remain open until electrical power is applied, making them ideal for systems requiring continuous flow during normal operation.

Select the Correct Coil Voltage

Choose a coil voltage that matches your available power source.

Pressure, Temperature & Flow

Operating pressure, temperature ratings, and flow capacity vary by valve size and model.

Always review each product page for:

• Maximum working pressure
• Temperature range
• Flow rate
• Port size
• Connection style

Plastic body valves generally operate within lower pressure and temperature ranges than comparable brass or stainless steel valves.

Frequently Asked Questions

Are plastic solenoid valves safe for drinking water?

Yes. The plastic solenoid valves sold on ElectricSolenoidValves.com are lead-free and non-toxic. Most materials used comply with NSF/ANSI Standard 61 for drinking water system components.

What fluids can plastic solenoid valves control?

Plastic solenoid valves are commonly used with water, potable water, air, and other compatible low-viscosity fluids. Always verify media compatibility before installation.

What voltages are available?

Available coil voltages include:

• • 12V DC
  • 24V DC
  • 24V AC
  • 120V 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.

Are plastic solenoid valves corrosion resistant?

Yes. Engineering plastics provide excellent corrosion resistance, making these valves suitable for many applications where metal valve bodies are unnecessary.

Are plastic valves lighter than brass or stainless steel?

Yes. Plastic valves are significantly lighter than comparable metal valves, helping reduce weight and stress on piping systems.

When should I choose a plastic solenoid valve?

Plastic valves are an excellent choice when your application requires a lightweight, corrosion-resistant, lead-free valve for water, potable water, air, or other compatible low-viscosity fluids.
