In line double-acting flow control valves Type FT257/2

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).
