Features
• Connection form corresponds to the standard ISO 6149
with conical contacting surface for the O-ring.
• Metric connecting thread
• Seal works reliably against leakage due to O-ring seal
between screw-in threaded joint and connecting thread.
• Can be replaced world-wide.
Manatrol throttle check valves of the series 6F have met-
ric connecting thread. The flow can be finely adjusted in a
defined direction. A bypass check valve allows revers
free flow.
