ASCO Numatics, the world’s leading manufacturer of comprehensive fluid automation, flow control and pneumatics solutions, is pleased to announce two new products. During the upcoming Emerson Global Users Exchange 2013, being held at the Gaylord Texan Resort & Convention Center, Grapevine Texas, September 30-October 4, 2013, ASCO will highlight the improved range of 0.55 Watt low-power solenoid valves and the new stainless steel Redundant Control System. Both of these introductions extend our leadership position in the key industries of Low-Power technology and Safety Systems.
The new 0.55 watt low-power solenoid valves have improved SCADA system drop-out current performance and extend the range to include four additional valve series. ASCO 0.55 W low-power solenoid valves are now compatible with all 24V control systems with a leakage current less than 1.8mA, which covers nearly the entire installed base in North America. The new additions to the range include 2-way Normally Closed 8262H and 8223H 300 series valves and 4-way dual solenoid 8344H 300 series valves. Low power technology adoption has been most robust in Upstream Oil & Gas applications where power consumption is critical, such as in remote natural gas wellhead automation packages or remote tank monitoring systems which run on battery or solar power only.
With the introduction of the new ASCO stainless steel Redundant Control System (RCS), ASCO has extended its market leadership position in Pilot Valve Safety into corrosive environments and Upstream Oil & Gas applications. The ASCO Redundant Control System is the only pilot valve system that has no single point of failure that could result in an unwanted closure of the process valve. It is SIL 3 capable, which greatly reduces spurious trip rates and improves overall safety system integrity.
The new stainless steel Redundant Control System features 316L stainless steel valve bodies and pressure switches, making it ideal for use with dry natural gas and other aggressive media applications. Sharing the same control logic as the RCS, it achieves a high level of process safety and reliability by using a redundant, fault tolerant architecture, high diagnostic coverage, and automated testing. A keyed bypass allows for easy on-line maintenance of the RCS without process interruption.
