Manatrol throttle check valves of series F with fine ad-
justment of the flow rate for a defined flow direction. The
built-in check valve allows free flow in the counter direc-
tion with little flow resistance. A 2-stage needle provides
very exact setting of smaller flow rates with the first three
rotations of the adjustment knob. After 3 more rotations,
the valve is completely open. The valve setting can be
locked using a locking screw.
