Gas pressure regulator РЕД-2
Direct action pressure regulator with two-stage reduction РЕД-2 are designed to reduce high and medium pressure to medium and low pressure. The regulators are spring-loaded, with two stage reduction. They equipped with a built-in safety relief valve (SRV), which activates and releases excess pressure when the outlet pressure exceeds the preset value, and a slam-shut device (SSD), which activates and stops the gas supply if the outlet pressure exceeds or falls below the preset values.
