The DL-56 is a compact, high-performance pressure regulator featuring a unique dual-piston design. It enables precise pressure control up to 6000 psig (414 bar) with dome pressures as low as 40 psig (3 bar), all within the smallest footprint in its class.The regulator is based on the proven PR-56 Series, widely recognized as an industry benchmark for performance, reliability, and quality.Constructed from brass alloy 360, the DL-56 offers an optimal balance of economy and safety. A precision-engineered 316L stainless steel piston sensor ensures excellent sensitivity, repeatability, and extremely low operating hysteresis, confirmed by independent testing.The design is completed with a 316 stainless steel dome. Its freely rotating inlet ring allows easy alignment of the dome gas line during installation while maintaining excellent leak integrity.
