The Fisher Type 119 switching valve from Emerson can be used for on/off or throttling control of noncorrosive or mildly corrosive gases. It is designed to meet low-pressure gas application requirements in many industries. The 119EZ and 119EZS valves can be used as fuel gas valves for oil and gas natural-draft burners. They are designed with a built-in speed controller that allows opening speed to be tuned, which helps ensure proper ignition of the main burner.
