The DL-50 is a compact and robust design which employs a unique “DualPiston” set up that enables the user to control pressure up to 6000 psig (414bar) with as little as 100 psig (7 bar) of dome pressure.All of this is accomplished within the smallest envelope the industry has to offer.The regulator portion of this unit was patterned after the time tested PR-50 Series, which is widely recognized as a benchmark of performance and quality.Offering the utmost in economy and safety, this unit is constructed from 316L stainless steel. A carefully engineered diaphragm/piston sensor unit offers good sensitivity and repeatability. Completing this design is the addition of a 316 stainless steel dome unit. The inlet ring to the dome is freely rotating and captured by a high tensile snap ring. This feature allows easy positioning and alignment of the dome gas line within a customer’s system while maintaining excellent leak integrity.
