Product Description
This Emerson ASCO 553 Series spool valve is a 3/2 bistable pneumatic valve, giving three ports and two switching positions that are each held by their own solenoid rather than a spring return.
A 3/2 valve is typically used for single-acting cylinder control or as a pilot valve, and the bistable configuration means it holds its last commanded position even if power is lost, unlike a spring-return monostable valve. Flow capacity and pressure rating are not listed in our current data — confirm these with our technical team.
Supplied by Z&F Corporation; contact our team for datasheet or exact specification confirmation.
