Chemola™ Desco Valve Flush NSR

For Corroded and Frozen Valves

Chemola™ Desco Valve Flush NSR
 is a butyl flush formulated to free up and clean difficult-to-operate lubricated valves. Cuts residual gums, lacquer deposits, inert solids and corrosion deposits that make valves hard or impossible to operate.


Recommended Uses

Although not all valves are recoverable with Desco Valve Flush NSR, a popular maintenance suggestion is the periodic use of Valve Flush NSR. By doing this, many operators have found that valves remain operable through year of use under severe conditions. When the valve is again operational, inject the Desco synthetic lubricant recommended for the particular valve service.
