Ross Controls 501B91 Pneumatic Valve Sub Base Manifold

Ross Controls 501B91 Pneumatic Valve Sub Base Manifold is a side-ported ANSI size 1 sub-base assembly designed to mount under a base-mounted valve and form a compact multi-station pneumatic manifold with a 3/8" outlet port. Its dimensions are 2.8 inches long, 1.6 inches wide, and 6.2 inches tall (72 × 41 × 157 mm), with NPT threads for inlet and outlet connections and a Cv (flow) rating of 0.9 to 1.0. Weighing about 1.00 lb, this sub-base is configured specifically for a 3/8" outlet port and NPT threads, aligning with standard ANSI size 1 valve stations in Ross' base-mounted valve family. This sub-base enables the creation of multi-station valve banks in automated pneumatic systems by providing the supply and exhaust paths for each station in a compact form factor.
