In the water and wastewater industry, "good enough" is a liability. We deliver valves engineered for a lower Total Cost of Ownership (TCO) through superior materials, smarter design, and guaranteed long-term reliability.
See Our Valve SolutionsAn under-specified valve seems like a saving upfront, but it creates a cycle of compounding expenses that impact your bottom line and operational stability.
A single failure can halt plant operations, leading to service disruptions and emergency repair costs that dwarf the initial valve price.
Frequent repairs, seal replacements, and manual interventions for hard-to-operate valves consume valuable labor hours and spare parts budgets.
Poorly designed valves create high torque and pressure drops, increasing pumping costs. Leaking seals mean wasted energy and lost product, 24/7.
Leaks of treatment chemicals pose significant safety hazards and can lead to costly environmental compliance violations.

| Application Stage | Key Challenges | Recommended Solution Tier | Typical Materials / Liners |
|---|---|---|---|
| Sludge & Biosolids Handling | High solids content, extreme abrasion, potential for clogging, high viscosity. | Severe Service Tier | Ductile Iron (DI) Body / SS 316 Gate / Metal or Resilient Seat |
| Chemical Dosing & Disinfection | Aggressive chemical corrosion (chlorine, ozone, acids, alkalis), zero-leakage essential. | Severe Service Tier | PTFE Lined / Duplex SS / FEP Coated Disc |
| Raw Water / Sewage Intake & Screening | Debris, grit abrasion, high flow, need for robust and reliable isolation. | Process-Duty Tier | Fusion Bonded Epoxy (FBE) Coated DI / SS 316 Disc / EPDM or NBR Liner |
| Secondary (Biological) Treatment | Continuous operation (aeration), moderate solids, long-term reliability for process control. | Process-Duty Tier | FBE Coated DI / Duplex SS Disc / EPDM Liner |
| Tertiary Filtration & Backwash | Frequent, high-velocity cycling, requires fast actuation and durable sealing. | Process-Duty Tier | SS 316 Body & Disc / RPTFE Seat |
| Potable Water Distribution | Must meet strict drinking water standards, long-term leak-tight performance. | General Service & Utility Tier | NSF-61 Certified FBE Coated DI / NSF-61 EPDM Liner |
| Plant Utilities (Service Water, Drains) | General purpose isolation, cost-effectiveness, and dependable shutoff. | General Service & Utility Tier | Cast Iron (CI) or DI / SS 304 Disc / NBR Liner |
Find the right valve architecture engineered to solve your specific challenge within the water and wastewater treatment process.
For the most demanding applications like sludge lines, biosolids, and aggressive chemical dosing, where extreme abrasion and chemical attack cause standard valves to fail rapidly.
For high solids, our heavy-duty Knife Gate Valves with hardened SS 316 gates slice through media without clogging. For corrosive chemicals, our PTFE Lined valves provide a complete, non-reactive barrier, ensuring zero leakage and ultimate process safety.
For raw water intake, secondary treatment, and filtration backwash systems. These applications require robust valves that withstand continuous operation and frequent, high-velocity cycling.
Engineered for high-cycle applications. Features like an eccentric disc design, robust bearings, and superior seat materials (EPDM/RPTFE) prevent premature wear and ensure consistent, low-torque operation, reducing actuator stress and long-term energy costs.
For potable water distribution and general plant utilities, where the primary needs are certified safety, long-term leak-tight performance, and economic value.
Our standard workhorse, built to a higher standard. We use high-quality, a robust, fusion-bonded epoxy coating for long-term, reliable performance. The most economical choice without ever sacrificing quality.
As a source factory controlling the entire production chain, we build value and reliability into every valve. This is our commitment to reducing your Total Cost of Ownership.
Our in-house foundry gives us total control. Every batch is spectrographically analyzed to guarantee the specified corrosion and wear resistance, from Ductile Iron to Duplex steels.
We analyze your specific problem—abrasion, corrosion, or high torque—and engineer a solution. This includes custom material selections, innovative low-torque mechanisms, and specialized coatings.
Every valve undergoes rigorous hydrostatic and pneumatic testing. We provide full traceability with MTRs and hold key certifications like ISO 9001 for potable water safety.
"The chronic failure of our sludge line valves was a constant budget drain. The JRVAL High-Performance valves have been a 'fit-and-forget' solution, paying for themselves many times over in saved maintenance costs and eliminated downtime."
— Plant Superintendent, North American Municipal Water Authority
Let our engineers analyze your application and demonstrate how a purpose-built valve can lower your Total Cost of Ownership and bring stability to your operations.
We don't only sell generic valves. We provide engineered solutions tailored to the specific operating environment of your process area.
