Specifications
Needle valves and multiport valves isolate measuring instruments such as pressure gauges, contacts or transmitters from the process in progress. By closing these valves, instruments can be safely dismantled for operations such as recalibration or replacement. The venting option allows pressure to be released from the instrument via the needle valve.
In the standard configuration, the multiport valve is equipped with two additional connections, which can be used either for venting or for adding additional instrumentation. The use of a fixed-tip spindle, which does not rotate, reduces seal wear, thus extending component life, particularly in frequent opening and closing cycles. Finally, the valve's anti-ejection design enhances operating safety, particularly in applications subject to high pressure stresses.
The FCX-AIV series gauge and absolute pressure transmitters can be fitted with a 1-valve 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.
| Pressure | 414 bar (6000 Psi) |
| Material | 316 L STAINLESS STEEL |
| Waterproofing | PTFE |
| Connection | 1 Inlet - 1/2" NPT female |
| Assembly | The manifold is mounted directly on the transmitter.
All tests and manufacturing operations are carried out with the manifold mounted:
- Pressure and leak test at 1.5 x static pressure for differential pressure
for differential pressure transmitters, and at the permissible overpressure for gauge pressure or absolute transmitters
- Calibration with manufacturing equipment |
| Miscellaneous | Plug with drain 1/2" NPT 1/2" NPT plug |
| Applications | Closing and venting pressure measurement instruments For aggressive gaseous and liquid media that are not highly viscous or crystallizing, even in aggressive environments |
| Special features | Low-wear design thanks to non-rotating spindle end in valve bonnet
Low torque and smooth operation of the valve handle, even at high pressure
Enhanced safety thanks to anti-ejection design of the valve bonnet
Valve seat leak-tested to BS6755 / ISO 5208 leak rate A
Combination of valve and hook-up on request |
