Fisher V150 Control Valve with 1052 Size 20 Pneumatic Actuator | 1" | ANSI CL150

What pressure, flow and temperature is it rated for?

This unit is rated ANSI CL150, which corresponds to 285 psig at standard temperatures for carbon steel construction. Flow capacity and temperature limits are not specified in the listing; request the valve body material, trim type, and Cv value from the seller to determine suitability for your operating conditions. Fisher V150 valves are typically sized for flows ranging from a few GPM to several hundred GPM depending on trim and pressure drop.

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

The listing describes this as a general process control valve for hydraulic, pneumatic, and process applications, but does not specify previous service or oxygen cleaning status. Control valves used in oxygen service must be cleaned to CGA G-4.1 or ASTM G93 standards and constructed with oxygen-compatible materials and lubricants. Contact the seller to determine service history and whether oxygen cleaning has been performed or is feasible based on the trim and seal materials installed.

What should I inspect before putting it into service?

The listing states this unit requires re-certification before use. At minimum, inspect the valve body and bonnet for cracks or corrosion, verify trim and seat condition for wear or erosion, check packing for leaks, and bench-test the actuator for proper stroke and air-tightness. Confirm the actuator spring range and failure mode (air-to-open or air-to-close) match your process safety requirements, and verify the positioner or I/P converter (if present) is functional and calibrated.
