Smart valve positioner, straight stroke, single acting, failsafe
The C41 model (single-acting) of the TORLEO series intelligent valve positioner has an additional bypass output switch in the design of the gas circuit structure. In normal operation, turn the switch to the right to the end. If the main board of the positioner or the I/P of the pneumatic components is faulty, the switch is turned to the left in place, so that the intake air circuit is automatically switched to the output air circuit of OUT1. At this time, the user can adjust the The pressure of the air pressure reducing filter valve directly adjusts the control valve to the required valve position for on-site emergency rescue.
