ASC Pneumatic One-Way Flow Control Valves

Description

ASC flow control valves combine an adjustable restriction with a parallel check-valve path. The knurled adjustment controls flow in the throttled direction, while the check path permits return flow in the opposite direction. Select the nominal connection size for the air circuit and orient the valve to suit the required controlled-flow direction.

Flow-control function

The adjustable throttling branch and check-valve branch share the P and A connections. Check the circuit symbol and the body markings before installation; a flow-control valve is not a substitute for a shut-off valve.
