Woodward 8904-931

Product Introduction:​ Part number 8904-931 belongs to Woodward's 8904-series valve-and-actuator combined assemblies and is configured as a complete 3103 stainless-steel gas metering valve mated with a TM-55P proportional electrohydraulic actuator. Designed for industrial gas turbine fuel control, the TM-55P actuator receives command signals from an electronic controller and, through an electrohydraulic proportional drive system, precisely positions the rotating metering sleeve of the 3103 gas valve to achieve high-accuracy gas flow metering and regulation.

Woodward 8904-847

Product Introduction:​ This assembly combines a 3103-series stainless-steel gas metering valve with a TM-55P proportional electrohydraulic actuator as a complete execution/valve combined unit. Part number 8904-847 corresponds to the TM-55P proportional actuator configuration. Designed for industrial gas turbine fuel control applications, the TM-55P actuator receives command signals from an electronic controller and, through an electrohydraulic proportional drive system, precisely controls the rotating metering sleeve opening of the 3103 gas valve to achieve high-accuracy gas flow metering and regulation.

Woodward 8904-838

Product Introduction:​ This unit is a complete actuator-and-valve assembly in which Woodward mates a 3103-series stainless-steel gas metering valve with a TM-55 integrating electrohydraulic actuator. Part number 8904-838 is configured with the TM-55 integrating actuator. It is designed for industrial gas turbine fuel control; the TM-55 actuator receives command signals from an electronic controller and, through an electrohydraulic servo drive system, precisely positions the rotating metering sleeve of the 3103 gas valve to achieve high-accuracy gas flow metering and regulation.
