Emergency Shutdown Valve Quarter-Turn Operation Close Valve In Less Than A Second ESDV features are designed for accuracy and dependability ■ Trunnion-mounted ball valve ■ Fail-safe spring return actuator ■ Low emissions design ■ Anti-blowout stem configuration ■ Fast response time 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. ■ Valve Type: Trunnion mounted full port ball valve ■ Body Style: Side entry, forged body ■ Actuator Type: Single-acting, spring return ■ Instrumentation: Pneumatic ■ 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
