The units are designed to close in less than 3 seconds and provide Class VI shutoff. The integrated speed controller reduces installation cost associated with using an external speed controller. The 119EZ and 119EZS are retrofitable to existing burner systems in the field.
The Fisher Type 119EZ and 119EZS are based on the compact, field-proven, and reliable Fisher Type 119 control valve platform. The new main burner valve shares the same internals (diaphragm, disk, orifice, and springs) as the Fisher Type 119, which has been used for more than 25 years on burners in the oil and gas industry.
“The design requirements of burner systems provided a great opportunity for the engineering team to develop new technology that improves the tuning process and helps simplify customer installation,” said Thomas Weyer, director of upstream business, regulator technologies, Emerson Automation Solutions. “By integrating an adjustable orifice to our valve we allow our customers to precisely tune the valve opening speed. Utilising feedback from the field, we were able to optimise the performance to create a product that meets all of our customers’ needs.”
