This document describes the operating conditions and procedures for using the Model 355 burner, as well as a method for removing contaminants using a 3-way solenoid valve.
This document provides step-by-step instructions for installing and operating the 3-way decoking valve option G6600-60058. The valve is designed to remove carbon and contaminants from the burner by switching hydrogen off and oxygen on. It is mounted on the rear of the Model 355 controller and controlled via a GC actuator. The guide includes wiring, flow setup, and safety precautions.
The valve body is mounted on the back of the controller. Hydrogen inlet and outlet tubes are disconnected, the copper line is removed, and the bulkhead fitting is slid through the valve’s mounting plate. The lines are then reconnected to the valve’s ports.
The valve is typically 24 VDC, but Varian GCs use 24 VAC, requiring a rectifier in the electrical line.
