Texas Integral Two-Stage Regulator Operation
Unlike two-stage systems, Texas integral twin-stage propane regulators are able to deliver propane to appliance at required pressure through one single regulator assembly. Often referred to as just a “twin-stage regulator”, it incorporates all the functionality of two separate regulators and is primarily utilized when the gas service line to the house or appliance covers a short distance and BTU load requirements are not extremely high. The first stage side consists of the regulator inlet and is connected to the pigtail at tank pressure. As gas enters the high pressure side of the regulator it is immediately lowered and delivered to the second stage side at a lower pressure. The second stage side of the regulator then lowers the pressure to about 11″ water column. Following these two subsequent stages of pressure reduction, the gas is delivered through the outlet, into the gas service line, and finally to the appliances downstream.
Important Twin Stage Regulator Information
The utilization of an Texas integral twin stage regulator is primarily limited to residential applications and similar applications where extremely high BTU requirements are not a factor. In gas systems where this type of regulator is installed, it is crucial to know that this is the only pressure regulation device between the tank and the house or structure being serviced. If your propane company recommends replacing the regulator, this suggestion should be taken very seriously. While Texas twin stage regulators are designed to commonly handle less than one million BTU/hr, they are not to be installed on small cylinders. All propane tank regulators are to be installed by licensed propane gas professionals.
