Description
The function of FT 257/5 valves is to control the flow and, if necessary, close it in one direction, while ensuring unobstructed flow in the other direction. These valves are valued not only for their aesthetic appearance, which fits well with the design guidelines of the equipment mounted on them, but also for their reliability. Proper sizing made it possible to achieve high mechanical resistance for components in a small space. The spring, made of high-resistance material, is positioned so that it does not close as a package during the conical, one-way valve opening.
All valves in the FT 257 series are equipped with:
- Effective metallic seal
- Flow linearity at opening
- Precise control over a wide flow range thanks to the dual reference system
- Wide flow control range
- The needle should not leave its place even in the maximum opening position
- Stable position thanks to an internal screw in the knob
- Quick Panel Mounting (Nuts [G] are available on request)
The check valve is set to 0.5 bar.
