9907-1198 压力转换器

Woodward’s second generation current-pressure converter (CPC-1) 25 bar, Zone 2, simplex version with enhanced dynamic characteristics is an electro-hydraulic pressure regulation control valve for positioning valve servomechanism/actuators in single-acting steam turbines. The CPC-1I addresses one of the industry’s number one reliability issues with oil contamination that affects equipment uptime and performance.

The CPC-I accepts the 4-20 mA pressure demand signal and precisely controls the oil pressure to precisely position the single-acting turbine control valve. Accurate and stable steam valve control is directly related to turbine speed and load control
The improvement of the system and the reduction of mechanical wear of the system.
