The Magna Flow Control Valve with an easy to read micrometer dial offers an amazing 1100 precise set points to accurately control flow of gases or liquids. The extremely high CV of the Magna Flow control valve enables very high flows for whatever media is being controlled, up to 200 PSIG pressure or full vacuum. Linear flow characteristics provide easy to set and precise metering of gases and liquids for almost any application where accurate results are required.
Available in either light weight impact resistant nylon or clear polycarbonate construction, the Magna Flow Control Valve offers superior strength and corrosion resistance, making it ideal for use in hundreds of different applications. Simplicity of construction, with removable top and bottom caps, provides easy disassembly for cleaning or maintenance without removing the valve from service. Proven O-ring seals provide a positive zero tight shut-off. Replacement of seals, if required, is quick and easy because disassembly is simple and fast. The Magna Flow Control Valve offers all these features at a very affordable price. |

The deltaflow flometer is continiously developed and inprooved and we hold several patents on the deltaflow Technology. But we do not only rely on our own know-how %u2013 systec is furthermore co-operating with well known partners sich as the institute for flow mechanics of the University of Erlangen oder the PtB in Braunschweig.
Due to the special probe profile the deltaflow can assure a high level of precision and excellent process viability, even in extreme conditions causing the lowest residual pressure loss. The deltaflow has been installed several thousand times.
Typical Applications are flow measurement of steam, perssurized air, water, liquids, stack gas, flare gas, natural gas.
Typical industries where our deltaflow integrating pitot tubes are used are Power Plants, Chemistry, Petrochemistry, Gas- and Oil Exploration, waste water plants.
The program to size and design the deltaflow is very self-explanatory and you can download it for free from our web-page as a Windows file (Windows 9x, 2000 and NT).
You can find more details in the referring information sheets. At the bottom of this page you can find links to the information sheets and to the software |

CNG Series
Single Tower Natural Gas Dryers
CNG Series adsorbers are single tower dryers designed to remove water vapor from Compressed Natural Gas in small to medium gas flow rates. Located at the inlet of the booster compressor, our unique binderless molecular sieve insures dry, pipeline quality gas (-80°F dew point or better) with minimal odorant fading.
Mobile, stationary and contracted regeneration packages available.
Single tower adsorption towers are an economical alternative to twin tower drying systems in CNG vehicular fueling stations which see intermittent or small gas flow rates (up to 300 scfm).
Down-flow design minimizes fluidization of the adsorbent insuring maximum life.
Optional Moisture Monitor & Alarm package for early performance degradation alert.

The gas pressure regulators (RTP) are designed to reduce natural gas pressure from medium to low one, and to keep the gas pressure rate independent on input pressure and flow changes. The regulators are suitable for domestic as well as for industrial installations.
Description
Single stage
Single stage gas pressure regulators have diaphragm - spring single stage pressure regulator with the lever system control element.
Double stage
Double-stage gas pressure regulators have two stages of pressure reduction, both with diaphragm-spring control.
The RTP gas pressure regulators are equipped with the following safety devices:
* The over-pressure and under-pressure shut-off
* The relief valve
Our regulators meet requirements of standard EN 12 279
We are producing various versions and sizes, as an example we are presenting double stage regulator
