Redundant Control System


Florham Park, New Jersey – ASCO, the world's leading manufacturer of Solenoid Valves, has expanded its product offering to meet the increasing requirements of critical system operation such as Emergency Shutdown Systems.

As an addition to ASCO's Process Valve System technology, RCS was designed to meet the expanded national and international hazardous location requirements for safety systems, high reliability, and critical control applications.

The RCS Solenoid Valve Assembly allows the end-user to specify a normally closed, normally open or double acting constructions in redundant control "2oo2" (two-out-of-two) or single solenoid with back-up "1oo1" (one-out-of-one) operation. All constructions are available with "automatic on-line testing" of the solenoid valves and "partial stroke testing" of the process valve.

According to George Laubenstein, ASCO product manager, "In order to maintain plant efficiency, RCS provides users with a maintenance/ by-pass mode, which permits service to the device without taking the process valve off line. This allows the plant to maintain production without jeopardizing its safety.
