Inline Check Valves
JAECO’s inline check valves are engineered to prevent reverse flow, protect equipment, and maintain dosing accuracy in chemical, metering, and process systems. Every valve is designed to seal quickly and reliably, flowing in one direction only.
We offer a full range of ball, spring-loaded, poppet O-ring, and high-viscosity models. Valves are available in materials such as 316 stainless steel, Alloy 20, and Hastelloy C to ensure compatibility with your pressure, fluid, and chemical requirements.
Explore Our Check Valves
Ball Check Valves, No Spring
Ball check valves use a compact design to allow flow in one direction while preventing backflow. These valves are available with or without springs and can be configured with single- or double-ball options depending on the system’s needs.
Poppet, O-Ring Check Valves
Poppet check valves feature a spring-loaded poppet that seals against an O-ring or elastomer seat for quick, reliable closure. They are a strong choice for metering systems or injection lines where consistent pressure control and leak prevention are critical.
Spring Check Valves
Spring-loaded check valves are engineered to close quickly under flow reversal. Their responsive design makes them ideal for dynamic systems where minimizing backflow is essential to maintain dosing accuracy.
Stainless Steel Check Valves
Built entirely from 316 stainless steel, these valves offer excellent corrosion resistance and are suitable for high-pressure environments. They’re widely used with metering pumps and in chemical systems requiring long-lasting components.
High-Viscosity Check Valves
High-viscosity check valves are designed to handle thicker fluids without clogging or failing. They are a reliable solution for specialty chemicals and industrial processes with challenging flow characteristics.

Check Valve FAQs
What’s the difference between ball and poppet check valves?
Poppet check valves use a spring-loaded mechanism and seal against an O-ring or elastomer seat to provide reliable shutoff and leak prevention. Ball check valves use a metal-on-metal sealing surface and may be either spring-loaded or non-spring-loaded, depending on the application.
Are JAECO check valves compatible with metering pumps?
Yes. JAECO check valves are specifically designed for integration with metering pumps and are used in both new systems and replacement installations.
How fast can I get check valves shipped?
Most small orders ship within 48 hours. For large volumes or custom requests, contact JAECO for lead times and bulk pricing.
