Technical information

The gauge isolator needle valves FT 2291 (90° angle) are normally used to protect the manometer as they have the double function of dampening pressure shock, when opening, and of isolating it from pressure line. Subjected to strict tests, they ensure reliability and long life. A rotating swivel nut allows the user to plug the manometer, directing it in 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. Equipped with connectors FT 2299-24, they also allow the connection with 1/2” BSP port. Suitable for pressure up to 400 bar and temperature from -20° to +130° they can be panel mounted by use of panel nut (G), supplied on request.
