Description
The FT 257/2 valves allow you to control the flow in both directions. The valve is equipped with a needle that provides the following:
- Effective metallic seal
- Flow linearity at opening
- Precise control over a wide flow range
The typical painted and FT (standard) screen-printed aluminum handwheel is equipped with a scale, which, together with a metal ring with a key and a fractional scale, forms a dual reference system, making it easy to identify the flow state. The locking screw in the handwheel ensures stable flow values, preventing accidental adjustments or displacements caused by vibrations and unwanted shocks.
