This product is a kind of output apparatus for gas pressure reduction. It can adjust pressure of all sorts of gaseous apparatus. It can be connected with larger gas collector, middle collector, and some air supplies. It can get two types of output gas, each of which has distinct pressure in the rated range of pressure through adjusting pressure of two set of reducing valves. Each set of above valves has a emergency valve which has the effect of auto-protection to avoid overload or relief of pressure of gas-supply. The pipe manifolds of this series of products have 1～4 output hoses from which users can select. The pipe manifolds of air supply mainly match the air controlled analytic instrument for drilling fluid produced by us.
