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

What pressure, flow and temperature is it rated for?

This unit is rated ANSI Class 150. The listing does not specify flow coefficient (Cv), temperature range, or maximum differential pressure for this actuator/valve combination. Contact the seller for the nameplate data and any available documentation that would show these ratings.

What materials are the wetted parts?

The unit has a stainless steel inlet and chrome plated ball/disc seat with a composition seal. The listing does not specify the body material, stem material, or the exact composition of the seal. Request complete materials of construction from the seller, particularly if chemical compatibility or high-purity service is a concern.

What should I inspect before putting it into service?

The seller states this unit requires recertification before use to ensure proper calibration and safe operation. At minimum, verify the condition of the composition seal for cracking or compression set, check the chrome plating for flaking or corrosion, confirm the actuator diaphragm has no tears or age-related degradation, and bench-test the stroke and spring return action across the 0-18 range. Leak test the body-to-bonnet seal and verify the seat provides shutoff within your process requirements.
