ML7421/ML8824 Series 1800N Linear Valve Actuators
ML7421 and ML8824 series linear valve actuators are used with control valves in sizes ranging from DN15 to DN150 connection size, with 20mm and 38mm stroke. They are used in a variety of applications where control accuracy is critical.
ML7421 series provide 0...10Vdc or 4...20mA control of 20mm and 38mm stroke control valves. ML8824 series provide 0...10Vdc, 4...20mA, or floating 3-P control of 20mm and 38mm stroke control valves. The actuators are used with threaded valves in the V5011 and V5013 series, and flanged valves in the V5015, V5016, V5025, V5049, V5050, V5328, and V5329 series.
Varieties include 24Vac/dc and 230Vac power, manual operation, and visual position indication. ML7421 stroke timing is 108s or 210s runtime (for 20mm and 38mm stroke respectively), ML8824 with 20mm stroke can be configured for 40s or 80s runtime, while the 38mm version can be confiugred for 80s and 120s runtime. Actuators are rated at 1800N linear force and IP54 protection class. Accessories are available separately, such as high temperature kits.
