GE’s New Cryodisc Service Safety Valve Option Increases Plant Efficiency


New Option Reduces Leakage of Cryogenic Fluids, Cutting Plant Maintenance Costs

HOUSTON, TEXAS - To help power plant operators curb emissions and reduce maintenance costs, GE (NYSE: GE) today released the Consolidated* 1900 Series Universal Media Cryodisc safety valve option. Consolidated valves patented Cryodisc technology, which deflects toward the nozzle to create a tighter seal than other technologies when exposed to isolated colder spots, helps reduce leakage of cryogenic fluids and correct small leak paths. The technology helps customers such as liquefied natural gas (LNG) processing facilities curb plant emissions and cut maintenance costs when keeping liquids at cryogenic temperatures.

The 1900 Series Universal Media Cryodisc safety valve option uses a unique disc geometry that is specifically geared towards the cryogenic application of leakage solutions. The Cryodisc diminishes the amount of process fluid lost during a valve leakage and ultimately reduces the potential need for intervention by maintenance personnel.

“The 1900 Series Universal Media Cryodisc safety valve option was developed specifically to address the lost hours and reduced plant productivity during a valve leakage,” said Nathan Brunell, marketing and product leader for GE Energy. “While other companies do offer safety relief valve options, the Cryodisc is designed with cryogenic technology in mind as an efficient solution to leaking valves. The unique geometry of the Cryodisc allows our customers to reduce plant downtime when leakages occur.”

In addition to reducing the leakage of cryogenic fluids at customers’ facilities, the Cryodisc self-corrects and closes small leak paths due to its disc geometry. The result is typically increased plant efficiency for customers and a decrease in the need for costly and time consuming compensatory behaviors, such as the physical de-icing of valves.

The 1900 Universal Media valve, introduced last year, meets customers’ needs for a pressure-reducing valve certified for both liquid and gas with no adjustments needed. Customers can operate the valve on either liquid or gas at the same pressure point, reducing inventory and simplifying the selection process. The valve provides exceptional blowdown, returning processes back to normal operating pressure quickly while reducing the amount of process media released from the system.

The 1900 Series Universal Media Cryodisc safety valve is among the product solutions that were part of GE’s February 2011 acquisition of Dresser, Inc.
