Working Principle & Core Performance

This pressure regulator adopts diaphragm pressure sensing and spring balance structure to automatically adjust the valve opening. It offsets inlet pressure fluctuation and flow variation, maintaining fixed stable outlet pressure for sample gas delivery. Built-in fine filter screen intercepts tiny particulate impurities in sample gas to prevent valve core abrasion and blockage. Strict pressure linear calibration is implemented before factory delivery to keep outlet pressure constant under long-term continuous gas supply. Internal pressure-bearing components undergo pressure fatigue testing to avoid pressure drifting during long-time operation.

Structural Design & Environmental Adaptability

The valve body is made of corrosion-resistant stainless steel with fluorine-free sealing elements, compatible with conventional industrial process gas such as hydrogen, natural gas and compressed air. Compact inline installation structure fits neatly inside sampling cabinets together with CRL-10-H-H filters and moisture probes. The whole assembly is dust-proof and splash-proof, adapting to thermal power hydrogen sampling cabinets, chemical sampling pipelines and outdoor gas metering stations. It is not affected by slight ambient temperature changes and meets the environmental adaptability requirements of industrial sampling loops.

Matching Equipment & Application Scenarios

Supporting accessory for MMS35, HygroPro, MTS6 series moisture transmitters and matched alumina probes. Widely used in generator hydrogen dew point sampling loops, compressed air drying detection pipelines, natural gas moisture monitoring sampling systems, matched with MG101 calibration equipment for stable standard gas output. It resolves measurement errors caused by unstable sampling pressure and protects moisture sensors from high-pressure impact damage.

Stability & Maintenance Advantages

Every PRE-6-40 assembly passes air tightness inspection and pressure stability testing before shipment to ensure unified batch performance. Manual pressure adjustment knob enables simple on-site pressure setting without professional tools. Wear-resistant valve core extends service cycle and reduces replacement frequency. Original GE pressure regulator avoids pressure surge damage to expensive moisture detection components. Shockproof sealed packaging satisfies long-term spare parts storage needs, and pressure regulation performance remains stable under dry constant-temperature storage environment.
