Product Overview

The Tartarini 040 series is a direct acting spring loaded regulator with an internal filter and relief valve, made for small and medium gas supply lines. The 040-C1/IRV version regulates without a slam-shut valve, while the 041-C1/IRV/OS-66 adds the OS-66 self-operated overpressure and underpressure slam-shut device for protection of the downstream equipment.

• Maximum inlet pressure 70 bar, inlet range 0.7-70 bar, outlet setting 0.7-20 bar

Typical Applications

Burner trains, furnaces and ovens, small industrial and commercial gas supply lines, laboratory gas panels and district pressure reduction points where a compact regulator with integral safety shut-off is required.

Selection Guide

Decide first whether a slam-shut valve is needed, then give the inlet pressure (up to 70 bar), the outlet setting (0.7-20 bar), the flow up to 900 Nm3/h and the port size 1/4 in, 3/8 in or 1/2 in. The 1 in BSP connection is standard; the relief valve can be deleted on request.
