- Max. Pressure 400 BAR
- Flow 220 LT/MN
The valves FT 257/2 allow flow control in both directions. They are equipped with a needle so to obtain: • efficient metallic seal; • flow linearity at the opening; • accurate regulation for a wide range of flow rate. The typical painted and FT ( standard ) serigraphed aluminium handwheel is equipped with a scale that, together with a keyed metal ring with graduated fractional scale, made up a double reference system to easily identify flow condition. A locking screw in the handwheel ensures stable flow values preventing accidental adjustments or movements due to vibrations and unwanted impacts. A ring nut (G) is used to carry out the panel mounting, on request.
