Surface-mount miniature pressure
regulator
Veriflo has launched a miniature pressure regulator for gas instrumentation applications that is compatible with the ANSI/ISA SP76.00.02 modular surface-mounting instrumentation standard
The Veriflo division of Parker Hannifin has launched a miniature pressure regulator for gas instrumentation applications that is compatible with the ANSI/ISA SP76.00.02 modular surface-mounting instrumentation standard The new instrument - DM3000 - allows flow control systems for process or laboratory instrumentation to be constructed in extremely small spaces, and can be installed in minutes on any standard substrate such as the Parker IntraFlow product

The highly compact DM3000 delivers excellent pressure regulation performance including a Cv (flow coefficient) of 0.1 typical and a maximum inlet pressure of 500 PSIG (35 BarG), with a choice of outlet pressure ranges of 1-30, 1-60, 2-100 or 3-250 PSIG (from 2 to 17 BarG).
The relatively high Cv and broad operating range means that the instrument is purged rapidly, and may be used in a wide variety of regulation applications.
Internally, the Veriflo DM3000 has a threadless type, non-tied diaphragm regulator.
Special design features provide fine control over regulation without compromising the dampening that guards against vibration in high flow conditions.
Fabricated from 316L stainless steel, with Hastelloy C-22 diaphragms and an Inconel poppet, DM3000 features a PCTFE seat with a poppet design that is self-centering, for repeatable positive closure.
The standard surface finish (Ra value) is 32 micro-inch or less.
The component operates over a -40 to +150 degrees F (-40 to +66 degrees C) temperature range.
This new regulator is supported by the Parker ISA/ANSI SP76.00.02 compliant substrate, IntraFlow, which features a novel slip-fit connection system that eliminates welding when building systems.
A key feature of IntraFlow is its intrinsic support for three-way flow paths.
Unlike the linear substrates in common use for semiconductor 'gas stick' delivery systems, IntraFlow maintains flow paths on a single plane - regardless of direction.
No manifolds on additional substrate layers are needed to implement the more sophisticated functionality required by sampleing systems.
This approach allows flow control substrates to be constructed with extremely low profiles (less than 3/4 inch/20 mm), and additionally optimises efficiency in terms of smaller internal volume sizes for faster sampling and purging cycles. Request a free brochure from Parker Hannifin ...
