Plastic Valves

Plastic Solenoid Valves offers plastic valves in a multitude of size and voltage variations. Cost effective and versatile, these valves are the perfect choice for a wide range of projects and automation solutions. Different port options are available and these come in normally closed or normally open options.

This page is for our plastic electric solenoid valves. If you are searching for (UPVC) Plastic Ball Valves click here.

Plastic Valve Main Parts

Valve Body - The valve bodies are made of solid plastic, either polypropylene (PP), polyoxymethylene (POM), or Nylon 66. Please see the technical details on each product page for the type of plastic used for each product.

Seal Material - All listed plastic solenoid valves contain an Ethylene Propylene (EPDM) Diaphragm, which have high chemical resistance properties and a wide pressure and temperature range.

Components - The internal components (plunger, spring, and orifice tube) are manufactured with stainless steel.

Are Plastic Solenoid Valves Safe for Drinking Water?

All plastic solenoid valves sold on do not contain lead or other toxic materials. Furthermore, most of the materials used in the configuration of our valves comply with NSF61 standards. NSF/ANSI 61 is the USA legally recognized standard for the assessment of drinking water contact materials, components and devices. Additionally, the EPDM seals and internal stainless steel components are non-toxic and safe to use with potable water systems.

Why is Plastic Used for Valves?

Plastic is a cost-effective body material for valves to use in media control applications. It is a durable material that is compatible with most systems and chemicals. Some benefits of using plastic valves are:

  • Lower priced than brass or stainless steel

  • Lightweight compared to the alternatives

  • Quick-connect variations available

  • Safe for drinking water - lead and BPA materials are used

  • Compatible with a wide variety of chemicals*

*Please consult a chemical expert to confirm the compatibility of these valves for your specific needs.

Are Plastic Solenoid Valves Made of PVC?

The bodies of our solenoid valves are made of either polypropylene (PP), polyoxymethylene (POM), or Nylon 66. We do also carry plastic ball valves, which are made of UPVC material.

Push Connect Valves

In addition to male and female threaded options, we carry several sizes of quick connect plastic valves. These are quick and easy to attach to a system that uses tubing instead of pipes, such as water filters, dishwashers, and hydroponic systems.

Choosing the Right Solenoid Plastic Valve

As you can see above, there is a large selection of plastic valves to choose from. Below are a few important criteria to consider before buying a valve based on your application.  If you still have any questions or need guidance, feel free to contact us for some assistance.


What type of media will be flowing through your system? Plastic valves are excellent for many liquids, water (potable and saltwater applications), air, and a variety of chemicals. Plastic water valves are safe for potable water.

Normally Open vs Normally Closed

The two types of solenoid valves are normally open and normally closed. A normally open plastic valve will allow media to run through it consistently until the electric actuator is energized to close the valve. Normally closed plastic solenoid valves will block media from flowing while in the off position and require electricity to open and stay open.

DC vs AC Voltage

What is the power source you plan to connect your valves to? The connections should match the source.  For example, if your power is coming from a standard house socket in the US, you would likely need a 120VAC valve.  If you are connecting your valves to a car battery, you would need it to be 12VDC.

Pressure & Flow Rate

The pressure range and flow rates vary depending on the size of the valve orifice and power ampages**.  These levels should be considered before attaching your valves. Generally, plastic valves have less of a pressure range than brass or stainless steel valves.

**All ranges are available on the specs of each product page.


Similar to the pressure and flow rate, the minimum and maximum temperatures will vary among each plastic solenoid valve. Generally, plastic valves have less of a temperature range than brass or stainless steel valves.
