If the supply air pressure is too high in your Siemens Valve Positioners, adjust the supply pressure according to the application requirements.
How to properly tune boosters on Siemens Valve Positioners?
To properly tune the boosters on your Siemens Valve Positioners, rotate the needle valve counter-clockwise to slow down the response and reduce overshoots. Alternatively, rotate the needle valve clockwise to increase valve response. After any needle valve adjustments, re-initialize the PS2. Also, use the buttons to move the valve assembly to each end-stop position.
How to prevent valve block failure in Siemens Valve Positioners?
To prevent valve block failure in Siemens Valve Positioners, install a coalescent filter on the supply line, directly upstream of the positioner.
