The 71000 series is a modified sweep angle valve designed to minimize fluid impingement through the body. This design includes very heavy guiding and durable trim parts to withstand harsh operation. Specific applications: visbreaker, hot hydrocarbon fluid and coking applications.	The 73000 Series control valve is especially suited to throttle highly erosive, flashing, and 2 phase flows. Specific applications: mining coal slurry ash handling hydrocarbon bottoms	The 75000 series tank drain valves includes a full sweep angle design and heavy duty plug design to minimize erosion impact from solids or debris found in tank bottoms. Available in 45, 60, and 90 degree angle configurations. Specific applications: Tank level control and pressure letdown applications commonly in reactor or crystallizer tanks.
