JARO JRV30 PVC Check Valve provides automatic non-return flow control, powered by a rust-proof SS304 spring and 100% virgin PVC-U body. Designed to absorb water hammer surges and prevent backflow, it features low cracking pressure and resilient EPDM/FKM seals for irrigation, water treatment skids, and industrial fluid networks. 100% factory pressure tested for zero-leak B2B supply.
Key Features & Advantages
Suction Line Liquid Prime Retention
Automatic non-return flapper seal retains liquid in the pump suction line after pump shutdown, eliminating repeat manual priming delays.
Integrated Debris Strainer Screen
Precision slotted PVC strainer cage screens out rocks, leaves, and large suspended debris, preventing impeller clog and premature pump wear.
100% Virgin PVC Construction
Molded from 100% virgin PVC-U resin under ISO 9001 certified quality systems, offering complete rust-proof performance in submerged water wells.
Hydrostatic Pressure Tested
Every JRV31 foot valve undergoes 100% factory hydrostatic shell and seat pressure testing prior to shipment, guaranteeing zero-leak back-seal performance.
Multi-Standard Compatibility
Supports global piping standards (GB, DIN, ANSI, JIS, NPT, BSPT), simplifying installation for international irrigation and water intake projects.

Frequently Asked Questions
Find answers to frequently asked questions about JARO PVC foot valves below. For technical selection, OEM solutions, or project-specific requirements, please contact our sales and engineering team.
A PVC foot valve combines a non-return flapper seal with a debris strainer screen, retaining liquid in the pump suction line to prevent pump dry-running while screening out solid particles.
It is installed submerged at the lowest intake point of a pump suction line in wells, ponds, or storage tanks. Ensure adequate submergence depth to prevent air vortex intake.
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.
