Industry Challenges We Solve

The water and wastewater industry operates under harsh conditions, from highly chlorinated and saline environments to sludge-laden wastewater lines. Our solutions are engineered to address:

  • • Corrosion from saline and chlorinated water environments
  • • Abrasion and erosion in sludge and effluent lines
  • • Scaling and fouling due to mineral-rich media
  • • Leakage and maintenance issues in continuous operations
  • • Need for lead-free and drinking water-safe materials
  • • Compliance with international standards for potable and reclaimed water

Every valve we manufacture is designed for low-torque operation, tight sealing, and zero leakage, ensuring uninterrupted flow and long service life in critical water infrastructure.

Frequently Asked Questions

1. What materials are best for valves in corrosive wastewater applications?
2. Are your valves suitable for drinking (potable) water systems?

Yes. We supply Lead-Free Brass and Stainless Steel valves that comply with NSF/ANSI 61 and WRAS standards for safe drinking water applications.

3. How do corrosion-resistant materials improve valve lifespan?

Corrosion-resistant materials like CF8M, Duplex SS, and PTFE-lined steel prevent surface degradation and scaling, significantly extending valve service life and reducing maintenance.

4. What valve types are recommended for sludge handling?

For sludge and slurry media, Knife Gate Valves and Plug Valves are ideal due to their unobstructed flow path and non-clogging design.

5. How can I reduce energy loss in water treatment systems?

Selecting low-torque, full-bore valves with precision sealing reduces flow resistance, improving energy efficiency and lowering pumping costs.

6. Do you provide valves compatible with seawater and desalination plants?

Absolutely. We manufacture Duplex, Super Duplex, and SS316L valves specifically for high-chloride seawater and RO desalination systems.

7. How long do wastewater valves typically last?

With proper material selection (DI, CF8M, PTFE-lined, EPDM), the lifespan ranges from 10 to 20 years, depending on sludge load and chemical exposure.
