DECELERATION VALVES - IN-LINE MOUNTING
These valves are used as cam controlled unidirectional flow regulators.
Normally mounted in line between actuator and directional valve for the dis-
placement of carriages or slides, they enable cam controlled acceleration or
deceleration of the moving mass.
A special internal check valve allows free flow the opposite direction.
To ensure correct functionning, connect “Y” to draining line.
