Chemical Compatibility Guide for Solenoid Valves – Select the Right Valve Material for Any Fluid
Find the Right Valve Material for Your Chemical Application
Choosing the wrong material for a solenoid valve in a chemical system can lead to corrosion, leakage, or even hazardous failure. That’s why Solenoid-Valve.World provides a detailed chemical compatibility guide to help you select the right valve body and seal materials for the substances you’re working with.
Whether you’re dealing with acids, solvents, water, oils, or industrial gases, we offer expert insights into which materials resist which chemicals—ensuring safe and long-lasting performance.
Why Chemical Compatibility Matters
A solenoid valve must maintain a tight seal and structural integrity even under aggressive chemical exposure. Material degradation can cause:
Valve failure or leakage
Dangerous chemical reactions
Increased maintenance costs
Reduced system efficiency
Selecting the correct valve material from the start prevents these issues and extends the lifespan of your system.
How to Use This Chemical Guide
1. Identify the chemical flowing through your valve (e.g., sulphuric acid, acetone, ammonia).
2. Check our compatibility tables to find suitable body and seal materials (e.g., PTFE, EPDM, FKM, Stainless Steel).
3. Match your choice with one of our solenoid valve models that offer those materials.

Common Materials and Their Resistance Profiles
Valve Body Materials:
Brass – Excellent for water, air, and non-aggressive fluids
Stainless Steel (316) – Highly resistant to acids, salts, and corrosive chemicals
PVC/PP/PTFE – Ideal for aggressive acids, alkalis, and solvents
Aluminium – Lightweight and cost-effective; limited chemical resistance
Seal Materials:
EPDM – Great for water, steam, and many alkalis
FKM (Viton®) – Excellent for oils, fuels, and many acids
NBR (Buna-N) – Suitable for oils and hydrocarbons
PTFE (Teflon®) – Universal resistance; great for harsh chemicals
