Why Choose The Aperval 101 Pressure Regulator
Why Choose The Aperval 101 Pressure Regulator
Value Elements
Accurate Gas Pressure Regulation: Pilot-operated design provides precise downstream pressure control, with an accuracy class of up to AC 5, supporting consistent natural gas delivery.
Stable Pressure Performance: Balanced regulator design helps maintain consistent outlet pressure despite fluctuations in inlet pressure and gas demand.
Wide Flow Range: Dynamic balancing technology provides excellent turndown capabilities, allowing the regulator to maintain reliable performance across varying natural gas flow requirements.
Simplified Maintenance: Top-entry construction allows technicians to access and service internal components without removing the regulator body from the pipeline, reducing maintenance complexity and downtime.
Compact, Efficient Design: Space-saving construction and low-noise operation make the Aperval 101 suitable for natural gas pressure reduction and distribution stations.
Flexible Pressure Control: Available in 2", 3" and 4" sizes, with multiple pilot configurations to accommodate different inlet and outlet pressure requirements.
Reliable Utility Performance: Designed for previously filtered, non-corrosive gases, providing dependable pressure regulation in medium and low-pressure natural gas distribution networks.
Comparison vs. Next Best Alternative
Compared to Direct-Operated Gas Regulators: Pilot-operated control provides greater pressure regulation accuracy and stability across changing flow and inlet pressure conditions.
Improved Pressure Stability: Balanced construction minimizes the influence of inlet pressure fluctuations on downstream pressure, supporting consistent gas delivery.
Greater Flow Flexibility: Wide turndown capabilities allow the Aperval 101 to accommodate varying natural gas demand without sacrificing pressure control performance.
Reduced Maintenance Downtime: Top-entry access simplifies servicing compared to regulator designs that require removal from the pipeline.
