Samson 3277 Pneumatic Actuator | Size 1 | 120 cm | ANSI CL150 | 6.0 Bar / 90 PSI

What pressure, flow and temperature is it rated for?

This actuator operates on a maximum air supply of 6.0 bar / 90 PSI and is rated ANSI CL150. Flow and temperature ratings are not specified in the listing; ask the seller for the stroke time, operating temperature range, and any nameplate data. Pneumatic actuators typically operate across -20°C to +80°C ambient, but valve body ratings impose separate constraints.

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

This is a pneumatic actuator that uses compressed air as its power source, not a component in direct contact with process gases. The listing does not indicate oxygen cleaning or oxygen service certification. For oxygen service applications, ask the seller whether it has been cleaned and whether elastomers and lubricants are oxygen-compatible.

What should I inspect before putting it into service?

The listing states this unit must be re-certified before use to ensure proper calibration and safe operation. Inspect the diaphragm or piston seals for cracks or hardening, verify spring integrity and travel stops, check mounting hardware and pilot valve condition, and bench-test stroke time and positioning accuracy against supply pressure. Leak-test the air supply connection and positioner (if fitted) at working pressure before coupling to a valve.
