Altek® Multi-z Anti-Cavitation Control Valve
Flowserve engineer and manufacture a Valtek Multi-Z control valve product which functions to eliminate cavitation under conditions of high pressure drop. That makes it ideal for severe servicing processes with trapped solids, cavitation, or erosion in these industries and applications:
Valtek® Multi-Z . Anti-Cavitation Control Valve
All plants

- Seal pressure control
- Water injection pump recirculation
Products have been customized to meet uniquely demanding performance requirements
The updated Multi-Z valve is available in globe and angle configurations as well as several material options, allowing it to be customized to meet specific application requirements. It features a multistage trim design and is available with multiple staging options. The Multi-Z valve’s axial flow design utilizes a large pass size, allowing it to pass much larger particles than conventional borehole or stacked disc technology.
The ideal anti-cavitation replacement that avoids costly safety recertification
The updated Multi-Z valve with standard trim has verified valve flow capacity (Cv) through computational fluid dynamics (CFD) and tests to match generally accepted industry capacities. This allows the operator to replace existing valves and avoids costly and time-consuming re-evaluation of the safety assistance system in a change management review (MOC).
Fully controlled solids and cavitation
Flowserve designed the Valtek Multi-Z valve to contain solids in a liquid medium, minimize high sound levels, tolerate high temperatures, eliminate cavitation formation, and resist corrosion.
