TOGNELLA FT291 | GAUGE ISOLATOR

The gauge isolator needle valves FT 291 (90° angle) are normally used to protect the pressure gauge as they have the double function of dampening pressure shock, when opening, and of isolating it from pressure line Moulded in high-resistance steel, protected by an accurate treatment, subjected to strict tests, they ensure reliability and long life. A rotating swivel nut allows the user to plug the manometer, directing it to the more suitable position, with a single blocking operation. The sealing, supplied as standard, and inserted in the nut, prevents any leakages between the connection and the gauge. For pressure gauge with taper threads, it will be necessary to use copper washers FT 1201.
