Single-stage regulators are commonly used as “line regulators” or Point of Use Regulators. They are used to reduce the pressure of a ring-main or common supply to whatever is required locally or for a particular machine or piece of equipment. The common supply pressure is kept both stable and relatively high to ensure that all users obtain their pressure/flow requirements. The single stage pressure reduction is very precise because the higher inlet pressure is itself stable.

Two stage regulators

Two stage regulators are used on gas cylinders to overcome the effects of the depleting pressure within the gas bottle. This is due to the changing balance of forces within a mechanical regulator whereby the outlet pressure of the first stage actually increases as the bottle pressure decreases. The second stage of regulation smooths out this intermediate pressure setting to lower it, and to precisely maintain, the lower set-point value. Our gas cylinder regulators or gas cylinder valves are available with brass or 316L stainless steel bodies and in ultra-high purity construction.
