Gauge Isolator Needle Valves

Isolator needle valves are normally used to protect the pressure gauge, since they have the double function of dampening pressure surge during opening and of isolating the pressuregauge entirely. A rotating (locating) swivel nut allows for accurate pressure gauge orientation. For pressure gauges with taper thread, it is necessary to use copper plug nuts (FT 1201) to be requested separately. They can be panel mounted by use of lock nut (G) which may be supplied on request. On request: • Versions with connections Female/Female (01) • For rigid pipes (04) • For fl exible pipes (05) • Seals in Viton (V) • Complete with lock nut (G), indicate whether KM or hexagonal
