Design Features
Pressure-actuated Backseat
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.
Axial-loaded Packing System
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.
Compliances to Nuclear Standards
Conval urea service valves comply to Appendix B of 10CFR50 and International Standard ISO 9001. Applications include high-pressure piping of urea reactors, strippers and condensers. Ideal for use with ammonium carbonate, nitric acid, and urea process fluids.
