Bronze vs. 316 Stainless Steel Solenoid Valves in Wastewater Treatment

Material Selection Determines Service Life

Wastewater treatment is a harsh operating environment. Continuous moisture. Chemical dosing. Outdoor exposure. Biological contaminants.

Material choice directly affects how long a valve performs before corrosion, leakage, or failure.

At Gould, we manufacture both cast bronze and full 316 stainless steel solenoid valves — because applications vary.

The key is knowing where each belongs.

When Cast Bronze Is the Right Solution

Cast bronze remains a durable and proven option for:

• Treated water lines
• Mild aqueous environments
• Indoor mechanical rooms
• Systems without aggressive chemical exposure

Our cast bronze bodies are rated for high pressure and precision-machined for tight tolerances.

In many wastewater systems, bronze provides decades of dependable performance when specified correctly.

When 316 Stainless Steel Is Necessary

More aggressive applications require higher corrosion resistance.

Gould’s KX Series features CF8M cast 316 stainless steel bodies with 316 stainless wetted components.

This is ideal for:

• Chlorination systems
• Chemical dosing lines
• Outdoor installations
• High-humidity pump stations
• Salt or brackish exposure

316 stainless resists pitting and crevice corrosion significantly better than lower-grade materials.

In environments where replacement is difficult or disruptive, upgrading material reduces lifecycle cost.

Seal and Coil Protection Are Equally Important

Body material is only part of the equation.

Gould offers seal materials including:

• EPDM
• Viton®
• Teflon™

Each selected based on chemical compatibility and temperature range.

We also offer:

• NEMA 4X watertight coil housings
• Explosion-proof (NEMA 7) options
• Class F and H coils for elevated temperatures

Wastewater environments demand complete system durability — not just a corrosion-resistant casting.

Built in the USA. Built to Last.

Imported valves often reduce material thickness or substitute internal components to meet price targets.

Gould valves are cast and assembled in Indianapolis.

We prioritize:

• Structural integrity
• Machined tolerances
• Repairability
• Long-term availability

If you’re specifying valves for corrosive wastewater conditions, the decision shouldn’t be based solely on upfront cost.

It should be based on how long the valve will perform without failure.
