Emerson has released the Fisher Type 119EZ and 119EZS main burner valves for burner systems used in oil and gas production. The 119 Series can help improve oil and gas burner performance, increase reliability and reduce capital and operational expense.
The 119EZ provides an adjustable opening speed for pneumatically controlled burners while the 119EZS incorporates a solenoid valve enabling it to be used with automated burner systems. The 119EZ and 119EZS are designed with a built-in speed controller allowing the unit’s opening speed to be tuned to meet the burner design. Tuning the opening speed of the main burner valve to match the burner design, helps ensure proper ignition of the main burner. The opening speed can be adjusted from 3 seconds for smaller burners to 12 seconds for larger burners.
The units are designed to close in less than three 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.
