Clampseal® urea service valves for high pressure piping of urea reactors, strippers and condensers are now available through Conval. These valves are ideal for use with ammonium carbonate, nitric acid and urea process fluids.

Conval’s urea service valves comply with all international standards, including ISO 9001, and come in ½ in. – 4 in. sizes with flanged end, hub connector or weld ends through ASME/ANSI Class 2500. Accessories include electric, pneumatic and hydraulic actuators; open, closed or both locking devices; single or dual-limit switches; and position indicator. Key features include pressure-actuated backseat; integral gland wrench; modular, interchangeable body styles; and an axial-loaded packing system.

Synthetic urea is created from synthetic ammonia and carbon dioxide and can be produced as a liquid or solid. Most urea is used in fertilizers because the nitrogen in urea makes it water soluble.
