F/9F Series Check Valve Flow Regulators

Detailed description:
Manatrol F series butterfly check valves provide flow control in a given direction of flow. The built-in non-return valve allows free flow in the opposite direction with little hydraulic resistance. A 2-stage needle valve is used for very precise control of low flow rates during the first three turns of the control handle. After 3 additional turns, the valve opens fully. The valve setting can be fixed with a locking screw.

Reverse flow control plate. Nominal set pressure: 0.4 bar
Operating temperature: -40 °C to +121 °C
