Two-valves manifolds are supplied with an isolation and bleed valve as standard. The isolation valve serves to separate the measuring system, such as pressure gauges, contacts or transmitters, from the process in progress. By closing this valve, the instrument can be safely removed for recalibration or replacement. In addition, the purge valve allows the instrument to be depressurized by connecting it to the atmosphere before dismantling, or to adjust the zero point.

The use of a fixed-tip stem, which does not rotate, minimizes wear on sealing components, prolonging their service life, especially when opening and closing cycles are frequent. Finally, the valve's anti-ejection design enhances operational safety, particularly in demanding environments.

FCX-AIV series gauge and absolute pressure transmitters transmitters can be fitted with a 2-way manifold, depending on the application and transmitter type.

Manifolds can be supplied mounted on transmitters or separately. If the manifold is mounted on the transmitter, the leak test and calibration operation are carried out on the whole assembly.
