Technical information
The valves FT 2257/5 have function of regulating and, if necessary, to shut-off the flow in one direction, allowing a free flow in the opposite direction. Appreciated for their aesthetic characteristics that indulge positively the constructive directions of the equipments on which they are installed, they are also a reliable solution. The proper dimensioning has made possible to obtain, in a little space, a great mechanic resistance of the components. The spring in high-resistance material is housed in such a way that it does not close as a pack during the opening of the taper single-acting shutter valve. Like all the valves of the series FT 2257 they ensure: • efficient metallic sealing; • flow linearity at the opening; • accurate control for a wide range of flow rate, thanks to the double reference system • wide range of the flow rate control; • impossibility for the needle to leave its seat even in the max. opening position; • stable positioning thanks to a screw inside the knob; • quickness in panel mounting (the ring nuts (G) are supplied on request). The check valve is set to 0,5 bar.
