Their function is to control and eventually shut-off the flow in one direction, allowing a free return in the opposed one. The suitable dimensions allow to obtain in reduced spaces a remarkable mechanical resistance of components. As all valves of the series FT 257 they ensure: • efficient metallic sealing; • flow linearity during opening; • accurate flow control, clearly visible with the double reference system; • wide control range of specific flow rate; • absolute safety against needle withdrawal also in the maximum opening position; • positioning stability, thanks to the screw inserted in knob. They are provided with plate connections mod. CETOP 03 or interchangeable with the widely used valves ( kind 60 ). The connection O-rings are equipped in series. Max. working pressure 250 bar
