V-Ring Piston Pressure Control Valve

A precision-engineered air compressor pressure regulator built with brass and aluminum alloy housing, featuring a 20.5 mm tube diameter and silver surface finish. Each unit is delivered individually and designed for direct replacement or upgrade in domestic and light commercial air systems. Its piston-driven actuation delivers 30% greater air throughput versus legacy diaphragm equivalents, supporting faster recovery and steadier line pressure. Critical to longevity is the V-ring piston seal — providing resilient, self-energising sealing action that resists extrusion, maintains low-friction movement, and sustains performance beyond 10,000 pressure cycles. As a dual-function component, it regulates compressor motor switching based on system demand and acts as a primary relief interface — adjustable via external screw for customised pressure thresholds. Verified to work with OEM gas meter assemblies and exhaust valves across common European compressor platforms.
