Parker IntraFlow^TM substrate fittings have been developed specifically for analytical, lab and other complex general purpose instrumentation flow control systems.  ISA/ANSI SP76.00.02 compliant, Parker IntraFlow^TM fittings provide maximum flexibility with minimal space requirements.  All flowpaths, regardless of direction, are maintained on a single plane within the system as there are no lower level manifold blocks required.  Contiguous fitting flow paths are intra-connected with slip fit pressure connectors, while a threaded pegboard provides connection force and rigidity when fittings are mounted with cap screws.  System assembly couldn't be simpler: a 5/32" hex head wrench is all you need to build with Parker IntraFlow^TM.

IntraFlow^TM Design Features:

* System size is reduced as much as 75% compared with conventionally plumbed systems, drastically reducing panel space, internal volume and purge times.

* Compliant with ISA/ANSI SP76.00.02 open architecture standards.

* Complex system assembly was never easier! No tube benders or cutters required, and no welding. All that's needed to assemble is a 5/32” hex head wrench!

* Every component on your Parker IntraFlow™ system can be reused when upgrading with emerging NeSSI Generation 2 & 3 technologies.

* All flow paths are on the same plane: Parker IntraFlow™ eliminates lower level manifolds to minimize system weight and leak potentials.

* Whether mounting a fitting to the standard 1/8" pegboard or a valve to the fitting, the same 10-32 x 1/2" SHCS is the only screw required.

* Heated Units are available.  Conventionally fabricated heated systems typically utilize convection heaters inside an insulated enclosure. Parker IntraFlow™ systems deliver the heat through conduction directly where it's needed: within 5/32” of the actual fluid flowpath. Replacing the standard 1/8” thick pegboard with a 1/2” thick internally channeled plate, electric heat cartridges are easily inserted to heat fluid to desired temperatures. A steam heat ported pegboard is also available.

The Parker R-max™ Stream Switching System is a multi-functional system capable of integrating both stream switching and filtering into one unique, compact assembly.  Designed to control both gases and liquids in analytical systems, the R-max utilizes state-of-the-art surface mount technology to reduce leak paths, internal volume and dead volume.  Components can be easily removed and replaced without breaking process connections, and an internal self-purging outlet header eliminates the need for an additional outlet loop.

R-max™ Design Features:

* Surface Mount Technology enhances maximum system flexibility and enables the user to add additional streams to a system without interrupting installed units.

* PCTFE Sealing Technology provides maximum sealing capability for both gases and liquids to eliminate leakage often found when using elastomeric O-ring seat designs.

* Low Internal Volume insures maximum system efficiency by reducing purge time and expensive purge gas.

* Modular Valve Design offers maximum serviceability for quick and easy in-system repair and reduced downtime.

* Internal Loop Design eliminates the need for an external loop and provides maximum capability with minimum system footprint.

* Visual Position Indicator enables the user to easily determine valve position for maximum system safety.

* Low Actuation Pressure design for maximum sealing capability with minimum air supply needs.

* Patent Pending

K-Max™ is a Teflon version of this Stream Switching System.  "Contact Us"  for details.

Vent Master (PDF 2.4MB)

Finally. A process analyzer venting system that resolves the conflict between the need for analyzer accuracy and the mandate for environmental compliance. Sample streams discharged from process analyzers have historically been vented to atmosphere for disposal. This method is not only convenient, but also provides a very stable reference pressure necessary to insure accurate and repeatable analysis results. As environmental legislation becomes more stringent, sample discharge to atmosphere is no longer allowable in many cases and analyzer engineers must choose an alternate method. Catalytic burners offer one alternative, however they do not completely eliminate emissions, have a limited flow capacity and require frequent maintenance. Discharge to a vent header that subsequently feeds a flare header and stack offers another choice, but the dynamic nature of the header is not conducive to pressure stability which compromises analysis accuracy. Complex vent systems installed plant-wide are also available, but they are highly engineered and expensive to install.

The Parker Vent Master™ is a process analyzer venting system that stabilizes pressure fluctuations for both accuracy and compliance.  Vent Master is an affordable, off-the-shelf solution that creates a constant one-inch water column vent header pressure to keep chemical/petrochemical process analyzers operating at maximum accuracy. The new system resolves analyzer accuracy issues associated with pressure fluctuations in flare stacks and other return points when analyzer samples cannot be vented to the atmosphere.  Vent Master is a solid state pump with an ultra sensitive pressure regulator that mixes a compatible gas with the analyzer samples to achieve a constant vent header pressure – even during times of plant upset, when pressure in the flare stack gets up to 20 psig. No matter if the analyzer effluent flow varies, or the backpressure fluctuates … Vent Master’s pressure regulator compensates, providing a stable environment. Plus its built-in economizer circuit keeps motive gas use to a minimum. The end result? Significant benefits across the board.

The Parker Vent Master™ is a totally mechanical integrated solution that actually creates a stable pressure within the vent header within 0.3” H20. Test results prove the Vent Master provides analysis accuracy within 0.06% over a vent header flow range of 0-18 SLPM with a flare header back pressure as high as 20 psig.

Vent Master™ Summary:

* Simple solution to achieve environmental compliance

* Eliminate costly catalyst procurement, replacement labor and disposal

* Maintains analyzer data integrity during plant upset conditions

* Production errors are minimized – the chances of off-grade product due to inaccurate data are negligible.

* Environmental compliance is easily achieved – eliminating the release of hundreds of tons of samples.

* Minimizes N2 consumption on Eductor models with the Economizer Circuit

* Compact package, easy to install and operate

* Pre-engineered, easy startup and commission steps

* Costs are cut – catalyst procurement and disposal are eliminated; the cost and administration of local emission permits are reduced.

* ROI is assured – usually in just a few months.

* Maintenance-free – Vent Master is a totally mechanical solution with virtually no moving parts. Set it. Forget it.

* Installation and operation are easy – various models and SLPM capacities offer a variety of options.
