When working with ozone systems or high-pressure applications, a dependable check valve is essential to ensure smooth operation and prevent costly damage. The CHK-16SV Stainless Steel Check Valve, specifically designed for ozone gas applications, offers durability, high performance, and long-term reliability. With a 1″ Female NPT connection and ozone-resistant Viton seals, this check valve is an ideal solution for both industrial and commercial settings.
Key Features of the CHK-16SV Check Valve
- Ozone-Resistant Design: The CHK-16SV is built with 316 stainless steel, ensuring it can withstand exposure to ozone gas without corroding or degrading over time. The Viton O-ring used in the valve is resistant to ozone, providing a positive seal and preventing leaks.
- Rebuildable and Serviceable: One of the standout features of the CHK-16SV is its simple yet effective design. The check valve can be easily disassembled, serviced, and rebuilt, making it an excellent long-term investment. If the Viton O-ring ever requires replacement, it can be quickly swapped out without the need to replace the entire valve.
- High-Flow Capacity: With a spring-loaded design and a 2.5 PSI crack pressure, the CHK-16SV allows for a high flow of ozone gas while maintaining a tight seal when needed. This ensures efficient gas flow while preventing unwanted backflow.
- Robust Construction: All critical components, including the spring and plunger, are made from stainless steel, ensuring durability even in high-pressure environments. The valve is designed to operate reliably under pressures up to 1500 PSI and temperatures ranging from -10°C to 105°C.

| CHK-6SV | 3/8″ | 2.165″ | 0.866″ | 0.22 lbs |
| CHK-8SV | 1/2″ | 2.165″ | 1.063″ | 0.286 lbs |
| CHK-12SV | 3/4″ | 2.677″ | 1.417″ | 0.638 lbs |
| CHK-16SV | 1″ | 3.268″ | 1.693″ | 1.056 lbs |
Common Applications
The CHK-16SV stainless steel check valve is incredibly versatile and is commonly used in a variety of ozone and oxygen systems, including:
- Ozone Gas Backflow Prevention: Protect ozone generators from backflow that can damage sensitive components.
- Oxygen Concentrator Isolation: Ensure that oxygen concentrators used in conjunction with ozone generators are protected from potential backflow contamination.
- Water Damage Prevention: Prevent water from entering and damaging ozone generators, especially in systems where moisture may be present.
- Mazzei Venturi Integration: The CHK-16SV check valve can be threaded directly onto Mazzei venturis, providing a more secure and leak-proof connection compared to standard Kynar check valves. For instance:
- 3/4″ venturi requires the CHK-6SV
- 1″ and 1.5″ venturi both use the CHK-12SV
The superior sealing of the CHK-16SV ensures no ozone gas or water leaks, making it an excellent upgrade for venturi-based ozone systems.
Why Choose the CHK-16SV?
When dealing with high-pressure ozone systems, you need a check valve that can stand up to the harsh environment and prevent any possibility of backflow. The CHK-16SV check valve offers:
- Durability: With stainless steel construction, this valve is built to last even in the most challenging conditions.
- Reliability: The Viton seal ensures a tight, leak-free connection that withstands the corrosive effects of ozone.
- Rebuildability: Over time, regular wear and tear may require servicing. The CHK-16SV can be rebuilt and serviced in the field, saving both time and money.
Conclusion
The CHK-16SV Stainless Steel Check Valve is an industry-leading solution for preventing backflow in ozone and oxygen systems. Its ozone-resistant materials, high-pressure capabilities, and rebuildable design make it a valuable addition to any setup that requires reliable protection against contamination and equipment damage. Whether you’re upgrading a Mazzei venturi or protecting an ozone generator from water damage, the CHK-16SV provides long-lasting performance and peace of mind.
