GO Regulator pressure regulators and fluid control valves

GO Regulator fluid components: PR-1 pressure reducing regulators, BP-3 back pressure valves, HPR-2 heated vaporizers, and DV1 packless diaphragm valves.

PR-1 series single stage pressure reducing regulators

PR-1 single stage pressure regulators provide precision fluid control across sample handling networks, specialty gas lines, and analytical equipment. Constructed from 316L stainless steel, electropolished wetted internal surfaces limit particulate generation across flows.

Adjustable outlet pressure ranges reaching up to five hundred pounds per square inch
Internal electropolished fluid path with surface roughness held below twenty-five Ra
Interchangeable seat materials including Tefzel, Kel-F, Vespel, and stainless alloys
Body fabricated from 316L stainless alloy with welded tube stubs and threaded ports

BP-3 series direct operating back pressure regulators

BP-3 back pressure regulators maintain stable upstream pressure through continuous throttling action. Unlike conventional on-off relief valves, smooth diaphragm regulation prevents hydraulic pulsations and pressure spikes across sensitive analytical analyzer loops.

Smooth continuous throttling regulation maintaining steady upstream line pressure

HPR-2 series heated vaporizing pressure regulators

HPR-2 heated pressure regulators incorporate heating chambers powered by steam or electric elements. Specifically engineered to vaporize liquid hydrocarbon samples and stop condensation during gas expansion, these units eliminate Joule-Thomson cooling across analyzers.

CT76 modular platforms and Cyclone bypass filtration

CT76 modular platforms built to ANSI/ISA 76.00.02 integrate regulators, diaphragm valves, and transmitters onto a unified baseplate with minimal dead volume. Cyclone filters provide continuous bypass action, separating fine particulates without causing sample transport delay.

Compact modular analytical panel architecture compliant with ANSI/ISA 76.00.02
Minimal internal internal volume eliminating analyzer sample transport lag times
Cyclone bypass filters delivering continuous self-purging particulate separation

GO Regulator manufacturing development and precision facilities

American manufacturer GO Regulator operates as a specialized division within Crane Co., delivering precision fluid control components for analytical instrumentation networks. Crane Co.

has pioneered flow handling engineering since 1855, developing dependable fluid equipment for global process industries. Modern manufacturing plants feature advanced multiaxis machining tools, electropolishing facilities, and cleanroom assembly zones for high purity gas components.

All regulator products comply with the European Pressure Equipment Directive PED under Sound Engineering Practice guidelines, ensuring structural integrity and operator safety across demanding industrial fluid loops.

Design principles and performance of PR-1 single stage regulators

PR-1 series single stage pressure reducing regulators serve as an established worldwide standard across gas chromatographs, sampling panels, and high purity semiconductor loops.

Machined from 316L stainless steel, the internal fluid passage undergoes mechanical finishing to less than twenty-five Ra followed by comprehensive electropolishing. This surface treatment minimizes micro-crevices and prevents contaminant accumulation along sample streams.

Four distinct seat materials, three internal orifice diameters, and six control spring selections enable precise tuning for aggressive fluids and gases with inlet pressures reaching six thousand psig.

Continuous throttling back pressure regulation in BP-3 systems

BP-3 series back pressure regulators provide continuous upstream pressure stability across analytical sample conditioning systems and chemical reactors. Unlike traditional on-off safety relief valves that cycle between open and shut states, the BP-3 utilizes continuous diaphragm throttling action.

This continuous throttling prevents pressure spikes, hydraulic shock, and sensor drift within sensitive laboratory analyzers. Fabricated from 316L stainless steel, Monel, and Hastelloy alloys, the internal fluid path withstands long-term throttling under aggressive acidic liquids and reactive gases.

Thermodynamic sample conditioning with HPR-2 heated vaporizers

HPR-2 series heated vaporizing regulators provide thermodynamic conditioning for liquid hydrocarbons and natural gas mixtures prior to chromatographic analysis.

Rapid pressure reduction induces severe temperature drops via Joule-Thomson cooling, which often triggers liquid dropout and seat freeze-up. The HPR-2 features an integrated heat exchanger powered by steam or explosion-proof electric coils, injecting thermal energy directly into the throttling area.

This continuous vaporization preserves sample homogeneity, eliminates condensation, and guarantees analytical accuracy across process monitors.

Packless metal diaphragm architecture in DV1 ultra-pure valves

DV1 series packless diaphragm valves are engineered for critical sample handling where zero external leakage and fluid stream cleanliness are mandatory. The internal fluid volume is entirely free of springs, bellows, packing glands, elastomeric o-rings, and lubricating oils.

Atmospheric isolation relies on a flexible metallic diaphragm that deflects smoothly via a quarter-turn manual lever or a compact pneumatic actuator.

This design endures over one million switching cycles without compromising external sealing or shedding particulate contamination into the sample fluid.

Technical selection guidelines and system engineering for fluid panels

Proper application of GO Regulator fluid control components requires thorough evaluation of hydraulic parameters during initial engineering selection.

Engineers must define minimum and maximum inlet pressures, required regulated outlet pressures, fluid phase, operating flow rate, and the sizing flow coefficient Cv. Corrosive service conditions require specialized Hastelloy bodies paired with chemically inert Tefzel or Kel-F seats.

Installing Cyclone bypass filters upstream removes suspended solids without sample transport delay, while ANSI/ISA 76.00.02 modular platforms streamline analyzer cabinet layout.
