Product Overview

The TARTARINI R/70, R/72, R/70-AP and R/72-AP are two-stage spring loaded pressure regulators designed for accurate pressure reducing control in domestic and industrial gas installations. R/70 versions use right-angle threaded connections while R/72 versions use horizontal axial connections.

Key Features

• Two-stage regulation with built-in relief valve and 0.5 mm internal filter

• Maximum inlet pressure 6 bar, 10 bar for R/70-AP and R/72-AP versions

• Outlet set ranges of 15-70 mbar standard and 70-300 mbar for AP versions

• Accuracy class up to +/-5% with lock-up pressure class up to +10%

• OPSO and UPSO slam-shut valves with manual reset, response time under 1 second

Typical Applications

The regulators are suitable for non-corrosive gases such as natural gas, LPG, propane, butane, compressed air and nitrogen. Typical applications include burners, furnaces, boilers, industrial burner trains and distribution lines that require accurate regulation and fast response under varying inlet pressure.
