Alloy Piston Air Compressor Regulator

This air compressor pressure regulator valve combines brass and aluminum alloy materials for strength, thermal stability, and weight efficiency. Measuring 20.5 mm in tube diameter and finished in silver, it is supplied individually and designed for straightforward installation. Its defining feature is the precision-machined piston mechanism — delivering 30% more airflow than conventional diaphragm alternatives — resulting in smoother pressure delivery and lower operational stress. The V-ring piston seal provides exceptional sealing consistency, high abrasion resistance, and stable performance across temperature fluctuations. It functions as both a pressure-sensing switch and a relief interface: users adjust the differential between start and stop pressures using an external screw, while surplus air escapes instantly through its overflow-structured body. Confirmed compatible with original gas meter assemblies and exhaust valves across multiple UK-market compressor brands.
