A check valve for urea service

A new in-line, axial check valve (photo) for urea and ammonia service was recently introduced. The new axial check valve complements this company’s extensive urea service product line, which includes Clampseal Y-, T- and angle-pattern globe valves, Swivldisc gate valves and Camseal top-entry ball valves in ASME Class 900 to 2500 ratings. Standard sizes range from 0.5 to 6 in., with flanged, butt-weld, hub, lens-ring or custom connections. All of this company’s urea-service valves are available in many alloys, including 316L Urea Grade, Ferralium 255, 310 MoLN, Duplex F51, Super Duplex F53, 25-22-2 SS, Zeron 100 and Titanium. Features include B16.34 design; integral gland wrench for concentric 360-deg packing load; in-line renewability; exceptional life cycle value; two-year warranty; standard helium leak testing; optional steam jacketing. — Conval, Enfield, Conn.
