DS3800NPCG is a Snubber Board developed by GE under Mark IV series. Mark IV regulates temperature, as well as the injection of water and steam. Startup, shutdown, and cooldown are all automated on the Mark IV. The technology automates operations and safeguards both the turbine and its operators from hazards. Both steam and gas turbines are included in this category. Since the late 1960s, approximately forty years, the Mark IV series has been developed and enhanced.
