Control Valves

DeZURIK BHP High Performance Butterfly Valves are used for everything from general service applications to viscous and corrosive liquids, corrosive gases, and steam. They are used in chemical, hydrocarbon processing, pulp and paper, water and wastewater, and HVAC industries worldwide. These ASME Class 150 and 300 valves are available with PTFE seats, Dual Seats and Metal seats to handle temperatures up to 700°F (370°C) or higher on application. To ensure accurate and reliable performance, BHP High Performance Butterfly Valves have been tested to the most demanding industry specifications: Performance tested in up to 5% consistency pulp stock isolation; Tested for over 1 million cycles in oxygen manufacturing service with zero leakage; Tested in hydrogen peroxide service for over 75,000 cycles with zero leakage; and accuracy to repeat signal changes as small as 0.5% of total signal.

DeZURIK PPE Precision Electric Control Valves are recognized industry-wide as the most accurate and reliable basis weight control  valve available. The Precision Electric Valve is a high-resolution control valve specifically designed for critical paper stock control, and is used for basis weight and headbox level control applications. It provides unmatched control accuracy, positioning and repeatability with up to 7760 repeatable positions. Positioning the valve plug is accomplished with a small, slow-speed motor, a high reduction drive, and rigid connections. Direct drive to the control module provides accurate feedback on plug position. A wide range of sizes and three control modes make this precision valve suitable for a broad range of critical control applications.

The DeZURIK RCV Rotary Control Valve is a quarter-turn, eccentric rotary control valve for throttling liquids, gases and slurries. The RCV Rotary Control Valve has been specially engineered for extremely precise throttling control in severe-service applications in the pulp & paper, chemical, power, petroleum and refining industries. The RCV is ideally suited for tough applications where high-pressure media contain entrained water vapor or suspended abrasive particles, including scaling liquor service, dirty steam service, kaolin slurry, lime mud, TiO2 slurry, fly ash slurry, coking, and other hard-to-handle liquids, gases and slurries. The DeZURIK RCV Rotary Control Valve combines the control accuracy of a globe valve with the strength of a severe-service ball valve. It provides precise throttling accuracy and control over a full 90° of rotation. Tungsten-carbide-coated trim components and design features provide superior erosion resistance. The RCV valve is designed for bi-directional flow capability and includes four trim options for flexibility. It is designed for ease of maintenance with no internal threaded components and self-aligning seat and plug. Flanged or flangeless designs meet ASME or ISA face-to-face dimensions.

DeZURIK VPB V-Port Ball Control Valves deliver superior performance and reliability required to optimize operations. This versatile valve is designed for control of fibrous suspension applications, as well as clean, dirty, viscous and corrosive liquids and gases. When operated by a high-quality DeZURIK actuator and controlled by one of many high-performing positioners, the DeZURIK V-Port Ball control valve can deliver control accuracy exceeding 0.5%. Control accuracy will increase process plant efficiency, improve overall profitability and reduce control valve life-cycle costs. DeZURIK V-Port Ball Valves are available in ASME Class 150 in sizes 1-20″ and ASME Class 300 in sizes 1-12″. DeZURIK V-Port Ball control valves feature one-piece body construction and are available in flanged or flangeless end connections. The solid one-piece body is available in ASME B16.10 or ANSI/ISA take-out dimensions. Four seat types are available. The flexible metal seat is designed to shear fibrous fluids and provides shutoff per ANSI/FCI 70.2 Class IV standard. Reinforced PTFE seats are typically used on clean fluid applications where ANSI/FCI 70.2 Class VI shutoff is required. The clearance seat provides maximum controllability and minimum hysteresis in applications that do not require tight shutoff. Rigid seats are available for abrasive applications including reclaimed fiber systems and applications with suspended chemical solids. The rigid seat provides shutoff performance per ANSI/FCI 70.2 Class IV.
