Pressure Regulators

Automated Confining Pressure Controller

Manufacturer: Vinci Technologies
Model Number: ACP

The ACP 700 is designed to generate and maintain automatically a constant confining pressure requested during core studies. It can also be used to maintain a constant differential pressure between the pore pressure and confining pressure. The system consists of a positive displacement pump of 250 cc capacity and 10,000 psi pressure, an automatic dual valve, a fluid reservoir and two pressure transducers for pore and confining pressure control.

Back-Pressure Regulator

Manufacturer: Vinci Technologies
Model Number: BPR

Vinci offers back pressure regulators designed to regulate the pressure in fluid flow studies. The BPR consists of two chambers separated by a piston with a needle connected to it on the lower side. The upper chamber receives the gas dome pressure and the lower chamber the process pressure. The BPR acts a comparator. When the dome pressure is higher than the process pressure the needle seals off the pressure and maintains the pressure. Inversely when the process pressure exceeds the dome pressure the needle opens up and the excess process fluid flows out. That way, on continuous flow these 2 stages are looped continuously and the process pressure is balanced to the dome controlled constant value.
