Throttle Check Valve, Series F
Manatrol throttle check valves of series F allow the adjustment of the flow rate for a defined flow direction. The medium can flow back in the opposite direction via the built-in check valve with little flow resistance. A two-stage needle allows for 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.
