Application: The sequence valve is used in cases where another consumer is connected to the circuit after a set pressure has been reached. The sequence valve ensures a controlled clamping sequence. Once a defined pressure is reached, another hydraulic circuit is opened. Note: The sequence valve can be screwed directly into the threaded connection for the swing clamp top flange and base flange types 6951KP, 6951FP, 6941KP and link clamp 6942KK, and with support elements for flange design 6964H and 6964HS. The oil must be supplied via the O-ring connection. The sequence valve can be screwed directly into fixtures as well.
