Throttle Check Valve Series F / 9F

Catalogue HY11-3500/UK

Characteristics / Ordering Code Manatrol throttle check valves of series F with fine adjustment of the flow rate for a defined flow direction. The built-in check valve allows free flow in the counter direction 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. ∆p γ

Flow rate Q [l/min] = Kv · Kv ∆p [bar] γ [kg/dm3] (γ for mineral oil
