Questions buyers ask

What pressure, flow and temperature is it rated for?

The maximum air supply is rated for 6.0 bar / 90 PSI, and the unit is rated ANSI CL150. Flow and temperature ratings are not specified in the listing—ask the seller for the controller's process temperature range and the actuator's spring range or force output, which will determine valve sizing compatibility.

What gases is it compatible with, and has it been oxygen cleaned?

This is a pneumatic actuator—it operates on instrument air and does not contact process media directly. The listing does not specify oxygen cleaning status. If you're installing this on an oxygen or other oxidizer service valve, verify whether the actuator and controller have been cleaned per CGA G-4.1 or your facility's requirements, and ask the seller about previous service history.

What should I inspect before putting it into service?

Inspect the diaphragm for cracks, hardening, or delamination, check all stem connections and linkages for wear or play, and verify the 3730-3 positioner calibration and zero/span settings. Stroke the actuator through its full travel with air supply applied to confirm smooth operation, proper seating, and absence of hysteresis. The listing recommends inspection and re-certification before installation.
