The valve plug position determines thecross-sectional area between the seat and plug.Depending on how the springs are arranged in the pneumaticactuator (see Data Sheets u T 8310‑1, u T 8310‑2 andu T 8310-3), the valve has two different fail-safe positionsthat become effective when the supply air fails:–Actuator stem extends (fail-close)The valve closes when the supply air fails.–Actuator stem retracts (fail-open)The valve opens when the supply air fails.Fig. 5: Type 3241-1 Control Valve, NPS ½ to 6, with Type 3271ActuatorFig. 5 to Fig. 8 show configuration examples.Fig. 6: Type 3241 Valve, NPS 8 to 122T 8012 EN
