The DL-57 is a compact, heavy-duty pressure regulator with a dual-piston design, providing precise control up to 10,000 psig (689 bar) with dome pressures as low as 58 psig (4 bar). This performance is achieved within the smallest footprint available in the industry.The regulator design is based on the proven PR-57 Series, widely recognized as a benchmark for performance, reliability, and quality.Manufactured from brass alloy 360, the DL-57 delivers an optimal balance of safety and economy. A 316L stainless steel piston sensor ensures high sensitivity, excellent repeatability, and exceptionally low operating hysteresis, validated by independent testing.The regulator is completed with a 316 stainless steel dome featuring a freely rotating inlet ring. This allows easy alignment of the dome gas line during installation while maintaining superior leak integrity.
