The semi-automatic switching pressure reducer for pipelines is a regulating device that reduces high-pressure gas to low-pressure gas and maintains stable pressure and flow rate of the output gas.

Classified by function

It can be divided into two categories: centralized and post based; According to different constructions, it can be divided into single-stage and two-stage types;

Classified by working principle

It can be divided into two types: positive action and negative action. At present, the common types of domestically produced pressure reducers are single-stage reaction type and two-stage hybrid type (the first stage is positive action type and the second stage is reaction type);

According to the medium

It can be divided into oxygen pressure reducers, acetylene pressure reducers, nitrogen pressure reducers, air pressure reducers, argon pressure reducers, hydrogen pressure reducers, helium pressure reducers, carbon dioxide pressure reducers, propane pressure reducers, natural gas pressure reducers, and stainless steel pressure reducers with corrosive properties.
