Structure: Air compressor pressure valve with 1/4" outlet safety valve with 2 gauges. Includes on/off switch. The piston seal uses a V-type seal design for reliable sealing, wear resistance, and stable performance. Advantage: Piston structure provides a flow rate 30% higher than traditional diaphragm types. Operation: Valve body includes an overflow port for rapid pressure reduction. Performance: Air compressor pressure valve switch delivers high precision and quick response. Feature: Compact size, lightweight, and easy to install. Product: Air compressor control valve regulator with gauges for rapid pressure reduction. The primary function of this valve is to regulate the start and stop pressure of the air compressor.
