The Durabla DFT Restrictor Check Valve (RCV) is a high-performance, spring-assisted in-line valve designed for applications requiring precise flow control and higher cracking pressures (2–40 psi). Unlike standard check valves, this model offers adjustable opening thresholds, making it ideal for HVAC, plumbing, and industrial systems where backflow prevention and pressure regulation are critical.

Constructed with durable stainless steel components and featuring threaded NPT ends, this 2″ valve ensures long-term reliability in demanding environments. Available in sizes from ¼" to 2½", the Durabla DFT series meets 450–6,000 CWP (Cold Water Pressure) ratings, delivering consistent performance across a wide range of pressures. Whether retrofitting existing systems or installing new lines, this valve’s robust design and precise engineering make it a trusted choice for professionals.

What’s the difference between this valve and standard Durabla check valves?

This Restrictor Check Valve (RCV) offers higher cracking pressures (2–40 psi), unlike standard Durabla valves which typically use lower thresholds for basic backflow prevention.

Can this valve be used in both residential and commercial HVAC systems?

Yes, its 450–6,000 CWP rating and stainless steel construction make it suitable for a wide range of applications, from residential plumbing to commercial HVAC installations.
