Drosel hidraulic bidirectional FT257-2

Double-acting shut-off

They allow flow control in both directions.

They are equipped with a needle so to obtain:

• metallic seal;
• flow linearity at the opening;
• accurate control for a wide range of flow rate.

A double reference system made up of a decimal scale on the handle and of a keyed metal ring with graduated fractional scale and divided into sectors allows the identification of flow conditions.

A locking screw in the handle ensures stable flow values preventing accidental adjustments or movements due to vibrations.

A ring nut (G) is used to carry out the panel mounting, on request.
