​​Product Description​​

The​​MOORE 42-30​​is a precision pressure regulator designed for accurate pneumatic control in industrial applications.It maintains stable output pressure across varying flow conditions and supply pressures,making it ideal for instrumentation circuits,test equipment,and process control systems

.

​​Application Scenarios​​

In a chemical plant’s instrument air system,the​​MOORE 42-30​​regulators were installed to maintain stable pressure for control valve positioners.When a compressor surge caused supply pressure fluctuations from 90 to 130 psi,the​​42-30​​’s two-stage design maintained a constant 60 psi output,preventing valve hunting and ensuring precise process control.This reliability avoided product quality deviations that could have resulted in$50,000 in batch losses

​​Technical Principles and Innovative Values​​

The​​MOORE 42-30​​employs a unique two-stage design with a pilot-operated pressure control system.The first stage uses a precision screw to apply spring force to a diaphragm assembly,which modulates pilot pressure.This pilot pressure then acts on a main diaphragm that controls the main valve opening,providing high gain amplification for precise output control

.

Innovation Point 1:The​​nullmatic pressure regulation system​​ensures maintenance-free operation by eliminating linkages,levers,and friction-prone components.This design provides exceptional stability and repeatability,with output pressure remaining constant despite significant fluctuations in supply pressure or flow demand

.

Innovation Point 2:The​​integrated safety release valve​​automatically vents pressure if regulation pressure exceeds the set point by 3 psi,providing critical overpressure protection for downstream equipment without requiring additional components

.

​​Application Cases and Industry Value​​

Case Study:A manufacturing facility implemented​​MOORE 42-30​​regulators across their pneumatic instrument network.The units maintained consistent pressure for critical measurement devices despite frequent compressor cycling,improving measurement accuracy by 15%and reducing calibration frequency by 30%.This resulted in annual savings of 25,000inmaintenancecostsandpreventedproductionerrorsestimatedat100,000 annually

​​Installation and Maintenance​​

Installation Preparation:The​​MOORE 42-30​​requires clean,dry instrument air for optimal performance.Ensure adequate pipe sizing and proper filtration upstream of the regulator.Mount in a accessible location allowing for adjustment and inspection

.

Maintenance Protocol:The nullmatic design requires minimal maintenance.Periodically verify output pressure accuracy and check for external corrosion.The epoxy coating provides excellent corrosion resistance,but in harsh environments,annual inspection of the diaphragm and spring assembly is recommended
