Spring check valve Drip-Pro™

for high flow rates

Reducing scorched particle contamination and post shut drip The Drip-Pro™ is the Spray Nozzle Engineering check valve for the Click&Dry™ series, also known as non-return valve and reflux valve, this valve works automatically without external control or intervention. The check valve allows fluid (liquid or gas) to flow in only one direction; it will crack (open) at a minimum pressure preventing inconsistent start up flow, and reseal (close) upon shut down to further prevent undesirable drips leading to scorched particles and product contamination. Check Valve: featuring the most cost effective, efficient and safest nozzle system A call from a spray dryer OEM revealed a problem with nozzle drips, which resulted in scorched particle, deposits at the fluid bed and post shut dripping, compromising the quality of the milk powder. The challenge to develop an anti-drip check valve, which would function reliably with the fluid path & difficult service conditions. We soon discovered this same problem was extremely common to many other customer’s dryers, for all dryer and commodity types. The result of our work was the unique Drip Pro™ patented design. As a result, OEMs set to work converting many existing plants with this first generation valve (Gen 1).
