The FT 291 isolator needle valves (angle) are normally used to protect the pressure gauge since they have the double function of dampening pressure surge during opening and of isolating the pressure-gauge entirely. A rotating (locating) swivel nut allows for accurate pressure gauge orientation. For pressure gauges with taper threads, it will be necessary to use copper plug nuts FT 1201, to be requested separately. Provided with connector FT 299-24 they also allow the connection of "Pressure gauges with connection 1/2" Gas". (As alternative it is advisable to use the mod. FT 290-12). Suitable for pressure up to 400 bar and temperature from -20 to +100 they can be panel mounted by use of lock nut (G) which may be supplied on request.
