Canalta Controls Ltd.

DBB ORIFICE FITTING

he Canalta DBB Orifice Fitting brings the unmatched safety of double block and bleed functionality to the already exceptional quality and performance of the Canalta lineup of orifice fittings.

Two valves separate the operator from the flow line - no need to block in the meter run with multiple ball valves. With separate equalization and venting for the upper and middle chambers, toxic or high pressure emissions through the top, putting personnel in danger, are virtually impossible in the rare event of lower valve failure.

Designed after HSE HSG 253 Cat 2 Isolation, and built to meet or exceed ASME and ANSI specifications, as well as to comply with the latest editions of AGA-3 / API 14.3 or ISO 5167, the Canalta DBB Orifice Fitting provides accurate flow metering over a long service life and superior protection from high pressures and toxic flow media.
