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.
On request: Versions AISI 316 code FT 2257/2. Viton seals (V). NPT Threads. Equipped with ring nuts (G). Handlewheel in ABS (mp). Lobes aluminium die-cast handwheel (RA).
