JARO JRV30 PVC Check Valve is an automatic non-return inline valve engineered to prevent fluid backflow and protect water pumps from water hammer shock in pressurized piping systems. Molded from 100% virgin PVC-U resin with resilient EPDM/FKM seals, it delivers low cracking pressure, tight sealing, and full flow efficiency across water treatment skids, agricultural irrigation, and industrial process lines. Every unit undergoes 100% factory pressure testing for zero-leak reliability.
Key Features & Advantages
Resilient 304 Spring Mechanism
Features a 304 stainless steel spring that retains tension over time for instant, leak-tight non-return sealing.
Low Cracking Pressure Sealing

Frequently Asked Questions
Find answers to frequently asked questions about JARO PVC check valves below. For technical selection, OEM solutions, or project-specific requirements, please contact our sales and engineering team.
A PVC check valve automatically permits forward fluid flow and seals tight when reverse flow occurs, protecting pumps and upstream piping from water hammer and siphon backflow.
It is commonly installed immediately downstream of water pumps, chemical dosing lines, or filtration skids where backflow could damage equipment or contaminate supply lines.
Operating strictly under ISO 9001 quality management, JARO enforces a comprehensive ‘Triple-Check Quality Protocol’ across all manufacturing stages: (1) On-site workshop patrol inspections, (2) In-line visual inspections at every injection molding machine, and (3) 100% manual hand inspections during final packaging. In addition, 100% of all valve products undergo hydrostatic shell and seat pressure testing before shipment.
