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

What pressure, flow and temperature is it rated for?

This unit is rated for ANSI Class 150, which corresponds to 285 psig at standard temperatures for carbon steel flanged connections. Flow capacity (Cv) and temperature limits are not provided in the listing; ask the seller for the nameplate data or trim specifications, as these vary significantly with the installed trim configuration. Fisher Type 1052 actuators are typically paired with V100-series globe valve bodies sized for moderate flow control applications.

What materials are the wetted parts?

The listing states the ball and disk are stainless steel/chrome plated and the seat is composite material, but does not specify the body, stem, or other wetted component materials. Fisher V100 bodies are commonly available in carbon steel, 316 stainless steel, or other alloys depending on the service—request the full material specification sheet or nameplate information from the seller to confirm suitability for your process fluids.

What should I inspect before putting it into service?

The listing explicitly states this unit requires recertification before use. At minimum, inspect the actuator diaphragm for cracks or stiffness, verify stem travel and seating with a bench test, check all pressure boundaries for corrosion or damage, and confirm the trim condition through a seat leakage test per ISA/ANSI standards. Replace any elastomers and packing, verify spring force matches your fail-safe requirements, and calibrate the positioner if installed—used control valves often have wear in the guiding and seating surfaces that affects shutoff performance.
