Flowserve Valtek MaxFlo 3 Control Valve Increases User Safety New Standard Shaft Blow-Out Protection Safety Feature with Upgraded Design Flowserve Corporation, a leading global provider of fluid motion and control products and services (NYSE: FLS), offers increased safety through improvements made to the Flowserve Valtek® brand rotary eccentric plug control valve design. The upgraded Flowserve Valtek MaxFlo 3 provides robust shaft blow-out protection in compliance with ASME standards developed to prevent the stem from being removed or ejected while the valve is under pressure. This important safety feature, stipulated by ASME B16.34 section 6.5.1, comes standard with Valtek MaxFlo 3 control valves.

"Accidents, safety incidents and failures have been attributed to other valves lacking these features," said Flowserve product manager Christophe Granger. "We've engineered a design that can operate in the toughest conditions." The Valtek MaxFlo 3 comes in both a standard length (ISA-75.08.02) and globe valve length face-to-face body (ISA-75.08.01 or DIN 3202 F1.) The new globe valve length option makes it easier for customers to transition from globe style valves to eccentric rotary plug valves when conditions permit. Retaining industry-superior aspects of the original MaxFlo design, the MaxFlo 3 uses a non-crossover shaft resulting in a significantly higher Cv for a given valve size and minimizes shaft damage from erosive process fluid. Other important features include tight bi-directional shut-off and low breakout torque. "All these features contribute to MaxFlo 3's precise control and reliability," Granger said. "High performance is first among the core design principles behind the MaxFlo 3 control valve." The Valtek MaxFlo 3 is available with Flowserve NR and VR actuators, and XL90, Logix500si and Logix 3000 series positioners.
