Instrumentation Valve and Manifold Selection Guide
Instrumentation valve packages are small in size but critical in service. Correct connection details, pressure rating and material compatibility help avoid field changes during transmitter, gauge and analyzer hook-up work.
Common instrumentation valve products
Instrumentation packages often include isolation valves, manifolds, monoflanges, check valves, needle valves, tube fittings, air headers and flushing rings. The correct product depends on the instrument connection, process side connection and maintenance access.
- Two-valve, three-valve and five-valve manifolds
- Monoflange and DBB monoflange assemblies
- Needle valves and instrumentation ball valves
- Tube fittings and compression connectors
- Air header distribution systems and flushing rings
Key buyer inputs
For an instrumentation valve RFQ, share pressure rating, material grade, connection thread standard, bore size, seat design, vent and drain arrangement, mounting requirement and any project documentation format.
Application fit
Instrumentation valves are used around pressure gauges, transmitters, differential pressure measurement, sample lines, air distribution and process take-off points. Compact selection can reduce leak paths and simplify maintenance.
Frequently asked questions
What is the difference between a manifold and a monoflange?
A manifold is generally used for instrument isolation, equalizing, venting and calibration. A monoflange mounts directly to a process flange and can combine isolation and vent functions in a compact body.
What connection details are needed for instrumentation valves?
Typical inputs include process connection, instrument connection, thread standard, pressure rating, material, vent or drain requirement and quantity.
