The aluminum body accommodates 1/4 in ports and is rated to operate up to 150 psi, enabling reliable actuation of compressed‑air lines in compact automation setups. This WT8551 family includes a range of voltage options, including 24 VDC NAMUR variants and 110/120 VAC configurations, reflecting ASCO’s broader portfolio of WT8551 valves.
