Series 4600 Ordering Guide

This series comes in two sizes, with flat gasket, a choice of three head styles, and four different alloys. Add a FH to any model number for a fixed head design. Add a Q to any model number for a vessel with an O-ring seal and split-ring without cap screws that limits the Maximum Temperature to 225 °C. Or, add an HP to your model number to achieve pressures of 2900 psi (200 bar) at 350 °C or 3000 psi (200 bar) at 300 °C.
