Water and wastewater treatment faces severe valve failures from extreme corrosion (acids, bases, salts) and abrasive solids. Operating large, high-pressure valves also presents difficulty, causing gearbox issues and downtime. JRVAL offers scientific, tailored solutions.
We select advanced materials (duplex SS, nickel alloys, special coatings) specifically for diverse wastewater chemistries, ensuring superior corrosion and wear resistance. For large valves, our innovative zero-angle misalignment lever provides ultra-precise, low-torque operation under high pressure. These innovations drastically extend valve life (up to 8x, 90% less wear) and reduce operating torque (40%), preventing costly leaks and failures. Proven in demanding applications, our technology delivers the reliable, cost-effective performance essential for continuous water/wastewater operations.
