ASCO's Stainless Steel Redundant Control System

ASCO’s Stainless Steel Redundant Control System (RCS) extends the company’s market leadership position in pilot valve safety into aggressive environments in midstream, upstream, and offshore oil and gas applications. The new stainless steel RCS features 316L valve bodies and pressure switches, making it ideal for use in environments where corrosion resistance is critical.

The ASCO RCS is the only pilot valve system with no single point of failure that could result in an unwanted trip of the process valve. By greatly reducing spurious trips, the ASCO RCS helps customers avoid unplanned downtime and the associated costs. It achieves higher levels of safety by incorporating a redundant, fault-tolerant architecture, high diagnostic coverage, and automated testing. The availability and reliability of the RCS provides the industry’s best choice for process valve diagnostics and actuation.
