Fisher Controls Type 1052/V100 Pneumatic Actuator Valve | Size 20 | ANSI CL150

What pressure, flow and temperature is it rated for?

This valve is rated for ANSI Class 150, which corresponds to 285 psig at standard temperatures for carbon steel flanged connections. The listing does not specify flow coefficient (Cv) or temperature limits for this particular unit, so contact the seller for those values and consult the Fisher 1052 technical documentation for size 20 trim capacity data. Operating range is stated as 0-18, likely referring to spring range in psi.

What materials are the wetted parts?

The ball and disk are stainless steel/chrome plated, and the seat is composite material. The listing does not specify the body material, stem material, or the exact grade of stainless steel used in the trim. Request a complete material certificate or original datasheet from the seller to verify compatibility with your process media.

What should I inspect before putting it into service?

The seller states this valve requires recertification before use to ensure proper calibration and safe operation. At minimum, inspect the seat and ball/disk for scoring or erosion, verify actuator spring integrity and diaphragm condition, bench-test stroke and shutoff at rated pressure, and confirm the pneumatic signal range matches your control system. Check all bolting for corrosion and verify flange faces are undamaged if this unit has been in service.
