High-Purity Four-Port Single-Stage Precision Line Regulator
DruvaPUR
The DruvaPUR high-purity four-port single-stage precision line regulator is used in gas supply systems for pure, inert, flammable, and oxidising gases and gas mixtures up to gas purity 6.0. It is not usable for corrosive and/or toxic gases and their mixtures.
High-Purity Four-Port Single-Stage Precision Line RegulatorIntroduction
Designed for unmatched precision, the Druva high-purity single-stage line regulator is engineered to deliver stable, low outlet pressures with exceptional accuracy. Its big housing diameter accommodates larger metal diaphragms, enabling extremely fine adjustment of back pressure at relatively high flow rates down to 250 mbar. The result is a precise, low-pressure supply with minimal hysteresis and reliable performance. This high-purity pressure regulator features four ports for flexible gas distribution in various sensitive environments.
