Flowserve recently introduced its new Multi-Z severe service control valve.

Flowserve spokespersons say the Multi-Z is designed to handle high-pressure drop applications where entrained solids are a problem, and is suited for system start-up and boiler-feed water recirculation applications.

Multi-Z features multistage trim that’s designed to eliminate cavitation. Additionally, a venturi outlet nozzle provides further trim and seat protection from high velocity, cavitation, and flashing. Its linear, multistage plug design provides high rangeability and throttling resolution.

Multi-Z’s multistage trim design is available as unbalanced or pressure-balanced, with the number of stages optimized to meet specific service conditions. The valve can be installed so media flow direction assists opening or closing. Available in sizes from 1″ to 4″, and in pressure classes from ANSI 300 to 2500, the Multi-Z accommodates diaphragm or piston actuators. Multi-Z’s body is available in angle or globe configurations, and in a choice of carbon steel, stainless steel, and CrMo steel. Custom options and configurations are available upon request.
