Electric control valve SAMSON
Series 240 Control Valves are available in nominal sizes ranging from DN 15 to DN 300 (½" to 12") and up to a nominal pressure PN 40 (Class 300).
Control valves in the standard version are suitable for temperature ranges between -10 and 220 °C (15 and 430 °F). An insulating section allows the temperature range to be extended to -200 and 450 °C (-325 and 840 °F).
The plug stem is sealed either by a self-adjusting PTFE V-ring packing or an adjustable packing. To meet stricter emissions control requirements, a stainless steel bellows is used. The Type 3241 Control Valve can be equipped with a heating jacket that may also include the bellows.
Series 250 Control Valves are used when large nominal sizes and/or high pressures are involved in process engineering, power plant or supply engineering.
In addition to globe, three-way and angle valves, four-flanged valve bodies with bottom plug stem guides, and valves with axial multi-stage throttling plugs, customized valve constructions to meet customer specifications can be engineered as well.
The valves are manufactured in nominal sizes from DN 15 to DN 500 (½" to 16") and for nominal pressures between PN 16 and PN 400 (Class 150 to 2500).
The standard versions of these control valves are suitable for temperatures ranges between -10 and 220 °C (15 and 430 °F). This temperature range can, however, be extended by using an adjustable high-temperature packing to a temperature range between %u201310 and 350 °C (15 and 660 °F) and by using a bellows seal or an insulating section to a temperature range between %u2013200 and 500 °C (%u2013325 and 930 °F).
Series 280 Steam-converting Valves are used to reduce both the steam pressure and steam temperature to optimize plant operation and heat efficiency in process plants, for example, in refineries, food and beverage, tobacco or pulp and paper industries.
Steam-converting valves are based on Series 250 Valves fitted with a flow divider St III and an additional spray water connection. They are available in nominal sizes ranging from DN 50 to DN 400 (1" to 16"), with nominal pressures of PN 16 to PN 400 (Class 150 to 2500) and for temperatures up to 500 °C (930 °F).
The Type DUV-C3 Steam-converting Valve from Welland & Tuxhorn is designed for high-pressure ranges and can be engineered with varying inlet and outlet sizes. The inlet nominal sizes range from DN 80 to DN 500 and the outlet nominal sizes
from DN 100 to DN 1600. Large amounts of spray water can be injected thanks to the integrated atomizing steam cooler. The valve can be operated in a wide load range.
