Control Valve Less Cavitation, Reduced Maintenance, More Reliability

Editor: Dr. Jörg Kempf

A new cast globe body for the Multi-Z anti-cavitation control valve from Flowserve reduces weight and shortens lead times for customers in the oil and gas, chemical, and power industries.

Most importantly, it reduces maintenance costs and improves reliability by virtually eliminating cavitation. To achieve this, the Multi-Z divides the pressure drop into three to six stages, gradually reducing the pressure and minimizing velocity spikes. In dirty service applications with particles in the process fluid, this staged pressure reduction also lessens 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.
