PF3WS and PF3WR are remote, separated versions of the manifold. PF3WS is the supply path and does not include a sensor. This type is mechanical only. The 1" main supply is oriented at 90° to the flow paths, and can flow through or be closed on the opposite end. 3 flow ranges are available, with up to 10 stations on the smaller two ranges, and up to 5 stations on the largest. Flow adjustment and stop valves are optional, and will match on every station. PF3WS is IP65 rated, and CE and RoHS compliant.
