Multistage Control Valve

The Multi-Z is well-suited for system start-up and boiler feed water recirculation. The valve features a multistage trim design that eliminates cavitation and provides extended trim life. The addition of a venturi outlet nozzle provides further trim and seat protection from high velocity, cavitation and flashing. The Multi-Z multistage trim design is available as unbalanced or pressure-balanced, with the number of stages optimized for specific service conditions. The valve can be installed so the flow assists either opening or closing. Available in sizes from 1-inch to 4-inch, and in pressure classes from ANSI 300 to 2500, the Multi-Z accommodates diaphragm or piston actuators.
