The ¼- and ½-in. Actuator Control System (ACS) is a compact range of standard, explosion-proof systems for the control of actuators on process valves. The range comprises solenoid-, spool- and manual-reset valves as well as filter regulators, and may also feature redundant components to prevent unplanned shutdowns. The modular ACS is manufactured in 316L stainless steel. Tested up to 150 bars, the system features an optimized flow path and is lighter, stronger and more compact than conventional panel-mounting assemblies. — ASCO Numatics Ltd., Skelmersdale, U.K.
