The Type 119 control valve is used for on-off or throttling control of noncorrosive or mildly corrosive liquids and gases, in applications such as fuel valves for heaters and treaters. It is designed to meet low-pressure liquid and gas application requirements in many varied industries. If the control valve requires maintenance, the trim can be exposed by removing two bolts and lifting the actuator assembly off the valve body without disassembling the actuator.
