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

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. Flow capacity (Cv) and temperature rating are not provided in the listing; ask the seller for the nameplate Cv value and the specific trim material to determine temperature limits. Fisher Type 1052 actuators are typically paired with various valve body styles, so flow characteristics depend on the specific V100 body configuration.

What materials are the wetted parts?

The valve body is 2" with a stainless steel/chrome plated ball/disk seat according to the listing. Body material (likely carbon steel or stainless steel), stem material, and seal materials are not specified; request the valve's material specification sheet or tag information from the seller. On Fisher control valves, the trim designation (e.g., standard, hardened, or corrosion-resistant) determines wear resistance and chemical compatibility.

What should I inspect before putting it into service?

The listing explicitly states this valve must be recertified before use. At minimum, inspect seat and plug for erosion or corrosion, verify actuator diaphragm integrity and spring condition, check packing for leaks during a seat leakage test per ANSI/FCI 70-2, and confirm stroke calibration across the 0-18 signal range. Verify all wetted materials are compatible with your process media, especially if previous service is unknown, and bench-test the positioner or controller if installed.
