Conval Severe Service valves are designed for best in class service life and in-line reparability. Designs include provisions for self-draining waterways and the elimination of collection points where the corrosive media (e.g. ammonium carbamate) can stagnate resulting in crevice corrosion and subsequent cracking.
The Clampseal® pressure-actuated backseat provides maximum valve integrity by ensuring a positive internal stop for the valve stem and disc assembly. The pressure actuated backseat also extends packing life by securely isolating the packing from the pressure when the valve is fully open.
The axial design ensures tight concentricity, which eliminates side loading of the packing and minimizes wear forces on the trim components. This feature is critical for superior valve performance.
Conval urea service valves applications include high-pressure piping of urea reactors, strippers and condensers. Our valves are designed for use with ammonium carbamate, nitric acid, ammonia, and other urea process fluids.
