RHT8013 - Uniweld RHT8013 Heavy Duty 2-Stage CO2 Regulator CGA 320

Precision Control for Industrial CO2 Applications

The Uniweld RHT8013 (Model 11105) is a high-performance two-stage regulator engineered specifically for the precise control of Carbon Dioxide (CO2) in demanding industrial environments. Unlike standard single-stage regulators that allow delivery pressure to rise as the cylinder pressure decays—a phenomenon known as the 'decay rise' or 'end-of-tank drift'—this two-stage unit maintains a constant output pressure throughout the entire life of the cylinder. This is achieved through a dual-diaphragm system: the first stage reduces the high-pressure gas from the cylinder to a preset intermediate pressure, and the second stage reduces it further to the user-defined working pressure. This architecture isolates the final delivery pressure from fluctuations in the supply source, ensuring unwavering stability.

Constructed with a rugged forged brass body and bonnet, the RHT8013 is built to withstand the rigors of heavy-duty usage. The internal components are protected by a sintered bronze inlet filter, which prevents dirt and debris from damaging the seating mechanism, a common cause of regulator failure. The unit features a CGA 320 inlet connection, the standard for Carbon Dioxide cylinders in North America, and is equipped with a washer to ensure a leak-tight seal. The large, easy-to-read gauges provide clear visual confirmation of both cylinder contents and delivery pressure, allowing operators to monitor system status at a glance.

Safety and reliability are paramount in the design of the RHT8013. It includes an internal pressure relief valve that automatically vents excess pressure in the unlikely event of a malfunction, protecting downstream equipment and personnel. The ergonomic T-handle allows for smooth, low-torque pressure adjustments, giving technicians fine control over gas flow. Whether used for MIG welding shielding gas, laboratory applications, or specialized industrial processes, the Uniweld RHT8013 delivers the consistency and durability required for professional-grade operations.
