To compliment our range of differential pressure gauges and transmitters, Fluidic offer a variety of 5 valve manifolds. Along with the functionality offered by 3 valve manifolds, a 5 valve manifold lets the instrument engineer carry out in-situ instrument calibration. This is done by connecting the “vent” port to a known pressure reference such as a dead weight tester.
Like 3 valve manifolds, 5 valve manifolds offer the instrument engineer the ability to isolate the differential pressure instrument for removal without interrupting the process. In higher static, but lower differential pressure applications, the equalisation valve may be left open during install to balance pressure across ports, protecting the DP instrument diaphragm from sudden pressure surges on one side. The equalisation port may also be used for in-situ zeroing of the associated differential pressure instrument.
Manifolds may be supplied for direct mount to the differential pressure transmitter, with standard 54mm centres design. The angled bonnet design, evident on the R5, U5, X5 and Y5 designs, prevents fouling of the valve head with transmitter electrical enclosure (/display). Alternatively, a flat faced manifold (V5) is offered as part of a panel mount design.
Fluidic have held a distribution agreement with Stewart Buchanan Gauges for over 20 years, and are proud to offer high quality manifolds from the local manufacturing facility in Scotland. Manifolds are typically manufactured in 316SS, but materials are available for more demanding applications including 6MO, Monel and Hastelloys. For North sea applications with traces of H2S we are able to offer 5 valve manifolds in NACE compliant materials. The usual EN10204 3.1 material certification requirements are a standard option on all manifolds.
Fluidic have a team of engineers able to help with your entire instrument application, including manifolds and pressure transmitters etc. Our engineers are product trained and familiar with a variety of different installations.
