High Accuracy Emergency Shutdown Valve Quarter Turn Operation Close Valve In Less Than A Second

Emergency Shutdown Valve Quarter-Turn Operation Close Valve In Less Than A Second

ESDV features are designed for accuracy and dependability

Full Open Position – Normal Operation
The ESDV provides minimal pressure Differential when Differential when the valve the valve is in full-open-open position.
The full bore ball valve virtually acts like a pipe minimizing process fluid turbulence

Full Closed Position – Emergency Situation

Setpoint pressure has been exceeded and the ESDV the ESDV has fully closed providing fully closed providing tight shutoff with its double-seated design.

■ Pressure Ratings: ANSI Class 150 - 2500

■ Shut Off: Soft seat - tested up to Class VI Metal seat - tested up to Class V

■ End Connections: RFFE, RTJ, weld end

■ Closing Time < 2 second (depending on size
