Gas pressure regulator РЕД-1
House combined gas pressure regulators "RED-1" are designed to reduce high and medium pressure to low.o low. Gas pressure regulators "RED-1" are spring-operated devices with two-stage pressure reduction. The regulators are equipped with a built-in safety relief valve (UCC), which activates and relieves excess pressure when the outlet pressure rises above the preset value, and a safety shut-off valve (MPC), which activates and stops the gas supply if the outlet pressure exceeds or decreases beyond the preset values.
