Flowserve Corporation, a leading provider of flow control products and services for the global infrastructure markets, announced the availability of Flowserve Multi-Z anti-cavitation control valves in a new cast globe body. The Multi-Z will be sold under both the Flowserve Kämmer and Flowserve Valtek valve brands.
“With the availability of the new cast body design we are able to provide shorter delivery times for customers with dirty service applications in the oil and gas, chemical and power industries,” said Jeff Parish, senior product manager, Flowserve Flow Control Division. “The Multi-Z virtually eliminates cavitation, which helps minimize maintenance costs and improves reliability.”
Cavitation occurs when the pressure of the process fluid drops below the vapor pressure, which allows small bubbles to form in the fluid that can then collapse on the valve’s surfaces and impart significant energy that can damage the valve trim. To achieve zero cavitation, the Multi-Z is designed to divide the pressure drop into three to six stages to gradually reduce pressure and minimize velocity spikes. Additionally, in dirty service applications with particles in the process fluid, this staged pressure reduction serves to lessen erosion, extending the life of the valve, decreasing maintenance and minimizing downtime.
Multi-Z valves facilitate quick and easy maintenance with a top-entry design that enables the valve body to stay in line while the trim is replaced or repaired.
