High purity dual stage gas regulator

High purity dual stage gas regulator
This two-stage chrome-plated brass pressure pressure or stainless steel pressure regulator is essentially a 2-in-1 pressure regulator.  This pressure regulator is designed for pressure control of high purity and non-corrosive gases in applications where constant delivery pressure is required. The pressure regulators feature metal-to-metal diaphragm seals to prevent gas contamination. It's also known as dual stage pressure regulator, double stage pressure regulator or multistage pressure regulator.

Ancor Sdn Bhd had supplied this gas regulator to various users that required stable outlet pressure performance.
