Questions buyers ask
What capacity and product purity does it produce?
This is a valve actuator and positioner, not a production unit—it controls valve position in response to process signals but does not produce, purify, or process any product itself. The Size 1 designation refers to actuator force output, which determines what valve sizes and pressures it can stroke; the listing does not specify stroke length or thrust output, so ask the seller for the actuator's force rating in Newtons or pounds and the available stroke to confirm compatibility with your valve.
What utilities, footprint and power draw does it require?
The unit requires instrument air at maximum 6.0 bar / 90 PSI supply pressure; consumption rate is not stated, but Size 1 pneumatic actuators typically draw 5–15 SCFM depending on stroke speed and cycling frequency. The 3730-3 positioner requires a control signal and may need loop power or separate DC supply; confirm electrical requirements with the seller, as Samson positioners vary by model variant. Overall length is 120 cm; ask the seller for the actuator diameter and mounting flange dimensions for installation clearance.
What is realistically involved in relocating and re-erecting it?
This is a compact actuator/positioner assembly that can be removed as a single unit once disconnected from the valve stem and air/signal lines; physical relocation is straightforward. Re-installation requires mounting to the valve yoke, coupling to the valve stem (verify stem diameter and thread compatibility), connecting instrument air supply and control signal, then performing full stroke calibration and positioner tuning. The listing states re-certification is required before use, which involves bench testing, calibration verification, and likely diaphragm/seal inspection or replacement depending on age and storage conditions.
