Fuel shutoff valve is a cost and time saver on turbines
05 April 2012
The AMOT 4420 fuel shut-off valve for gas turbines, has a close time of under 100ms and a special ‘vent’ port that reduces installation cost and time by eliminating the need for separate bleed valves. These compact, single-acting, pneumatically actuated, spring-return valves can be configured to relieve and vent pressure on the down-stream side upon shutdown. They can also be used in hazardous areas.
Developed for use in manual and automatic control systems, they are suitable for 10MW to 110MW turbines, used as starting air/gas bleed valves and unvented fuel/gas valves. Open/closed position switch indication is provided.
The shutoff is normally used alongside AMOT's 8402 gas turbine fuel regulating valve to provide a complete control system. It will accurately meter fuel to virtually any industrial or aero-derivative turbine, with a fast operating speed and large 500:1 turn-down ratio that allows a single unit to deliver fuel precisely from light off to maximum power.
