The 1/4" and 1/2" Actuator Control System (ACS) from Asco Numatics is a compact range of standard, explosion proof systems for the control of actuators on process valves. The range comprises solenoid valves, spool valves, manual reset valves and filter regulators and may also feature redundant components to prevent unplanned shutdowns. The new range has many applications in the process industry and addresses the growing demand for manifold systems, especially in applications where corrosive atmospheres are present. The high reliability modular ACS uses proven technologies and is manufactured in 316L stainless steel to resist aggressive environments. Tested up to 150 bar, the system features an optimised flow path and is lighter, stronger and more compact than conventional panel mounting assemblies. The components are connected by means of a versatile, leak tight coupling system and mounted on a vibration resistant and shock proof stainless steel base plate.
