DeZURIK V-Port Ball valves deliver superior perfor-mance and reliability required to optimize process per- formance. This versatile valve is designed for control of fibrous suspension applications, plus clean, dirty, viscous and corrosive liquids and gases.DeZURIK V-Port Ball valves feature one-piece con-struction and are available in flanged or flangeless end connections. They conform to or exceed North Ameri- can and International Standards for control valves. Superior control performance is designed into the geometry of the ball for critical management of flow. A locked ball-to-shaft connection...

The V-Port Ball valve design ensures unsurpassed accuracy over 90 of operation. Splined and locked ball-to-shaft connection, computer-designed ball, characterized v-port, low-friction bearings and low- friction packing combine to give superior control, including fast, accurate response to signal changes. These rigid connections effectively eliminate mechan- ical backlash and hysteresis.The V-Port Ball valve accuracy up to 0.5% means a resolution of up to 200 discrete positions of opera- tion. This exceeds industry valve dynamic perfor- mance standards as well as the accuracy levels of most alternative...

Utilizing computer-aided design and extensive flow-loop testing, the v-orifice was designed to provide the high rangeability and precision throttling required on fibrous suspension applications, as well as clean or dirty liquids and gases.The straight through flow passage provides maximum efficiency and excellent erosion resistance. The ball can be furnished with a range of high-alloy materials, all provided with a heat-treated nickel overlay. This overlay provides a non-porous and lubricous surface, resulting in greater corrosion resistance and less sliding friction. For abrasive and high temperature...

DeZURIK VPB valves offer the ultimate in face-to-face flexibility. The solid one-piece body is available in either ANSI or ISA take-out dimensions. V-Port Ball valves are available in flanged or flangeless con- struction to meet individual requirements and com- mon piping standards. For added versatility, these valves meet ISA, ANSI, IEC, ISO and EN face-to-face dimensions. In plants that have an installed base of both ANSI and ISA control valves, VPB users have been able to minimize storeroom inventory by stock- ing valve bodies, ISA retainers and ANSI retainers. A replacement valve with either...

V-Port Ball valves feature a full, uninterrupted, raised-face gasket surface that provides maximum gasket integrity. The gasket surface provides full seal contact area with ANSI B16.20 gaskets. > Diaphragm and PowerRac actuators rigidly con- nect to the valve and the positioner on the actuator housing. This accurately feeds exact valve posi- tion directly to the positioner. In addition, the close coupling of the actuator to the valve makes the total package as compact as possible > The self-aligning ball and seat on the VPB valve reduc- es lengthy setup time during repair and reassembly. Valves...
