Rotary Control Valves
Without dispensing with the state-of-the-art technology of the BED valve, from which it uses the smart solutions as, concave disc with optimized geometry in order to assure high flow rate capacity, self-centering seat ring with soft or metal sealing, and disc stop on the body in order to avoid excess rotation, the BXL line has been developed to meet industrial application needs at pressure classes ANSI 150 and 300 that can be served by a more standardized eccentric disc valve, with reduced cost and fast delivery, capable to achieve reference performance levels.
The EXL eccentric rotary plug control valve is versatile, with excellent cost-benefit ratio and can be used in most applications involving low and medium pressures, particularly where a high flow rate is required.
The robust non-crossover shaft remains out of the flow path and creates an unobstructed passage area, factors that enable EXL to perform duties in light and slightly erosive conditions.
The plug, which moves away from the seat immediately upon the first degrees of rotation, assures a long-lasting sealing capacity.
Although it incorporates some technical characteristics of the VB valve such as, self-centering seat and splined drive shaft that prevent motion loss, the project of VXL segmented ball valve has been developed with day-by-day applications in mind, namely with ANSI ratings 150 and 300.
Thus, the VXL line benefits from a rationalized range of options, the high level of interchangeability with other Valtek Sulamericana rotary valves and a high production volume, which make it one of the most competitive segmented V-notch ball valves of the world market.
The BED model bi-eccentric disc control valve is characterized by its flawless performance, which combines reliability and control accuracy.
Such characteristics, along with rangeability of 100:1, make this valve model a particularly advantageous option in applications involving high flow rates and small or medium differential pressures.
The double eccentricity causes the disc to move away from the seat immediately upon the first degrees of rotation, increasing controllability and seat lifespan.
Light body, with compact face-to-face dimensions makes for easy installation and maintenance tasks, while non-selective disc and shaft contribute to an extremely low operational cost.
