Asco Numatics has introduced the 1/4in and 1/2in Asco Actuator Control System (ACS), 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 demand for manifold systems, especially in applications where corrosive atmospheres are present. The modular ACS is manufactured in 316L stainless steel to resist aggressive environments. Tested up to 150bar, the system features an optimised flow path. 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. The system eliminates complex arrangements using panels, pipes and additional fittings and is pre-assembled ready for use.
