Fisher V150 Control Valve with Type 1052 Size 20 Actuator | 1" Body

What pressure, flow and temperature is it rated for?

The listing does not provide pressure class, Cv rating, or temperature limits for this unit. Fisher V150 valves are typically available in ANSI Class 150-600 with trim configurations for various flow capacities, but you'll need to ask the seller for the specific nameplate data, trim style, and any pressure/temperature stamps on this body. End connection type (flanged, threaded, socket weld) will also affect the working limits.

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

The listing does not state the previous service or whether oxygen cleaning has been performed. Standard Fisher V150 control valves are general-purpose units suitable for gases, liquids, and steam depending on trim material, but oxygen service requires special cleaning, compatible elastomers, and documented certification. Ask the seller for service history and whether it meets CGA G-4.1 or equivalent oxygen cleaning standards if that's your application.

What should I inspect before putting it into service?

The listing states this unit must be re-certified before use. At minimum, verify actuator spring range and calibration, check for seat leakage per ANSI/FCI 70-2 or your site standard, inspect packing for leaks and proper adjustment, and confirm positioner (if present) is functioning. Check plug-and-seat condition for erosion or wire-drawing, verify stem travel matches specified stroke, and test air supply response across the operating range. Service history will dictate whether soft parts or trim need replacement.
