Low pressure shut off valve and system

Filed:2020-04-30Pub:2023-05-23
Applicant:Engineered Controls International, LLC

A CO2 low-pressure shut-off system is described. The low-pressure shut-off system may include a low-pressure shut-off valve including a first valve inlet, a second valve inlet and at least one valve outlet, a solenoid valve including a valve inlet, a first valve outlet, and a second valve outlet. The solenoid may be configured to direct a flow of a pressurized gas from the valve inlet into at least one of the first valve outlet and the second valve outlet. The CO2 low-pressure shut-off system further includes a gas monitor electrically coupled to the solenoid valve. The gas monitor may be configured to transmit one of a first signal and a second signal to the solenoid valve to control the flow of the pressurized gas through the solenoid valve.

Combination valve for pressure building and final-line gas regulation

Filed:2021-06-17Pub:2023-05-16
Applicant:Engineered Controls International, LLC

A combination valve for pressure building and final-line gas regulation is disclosed. An example valve includes a body defining a first tank port and a second tank port, an outlet port, and a linking chamber fluidly connected to the second tank port. The valve includes a first piston diaphragm at least partially defining a first pressure cavity fluidly connected to the first tank port and a first plug operatively connected to the first piston diaphragm. The first pressure cavity is fluidly connected to the linking chamber when the first plug is in an open position. The valve includes a second piston diaphragm at least partially defining a second pressure cavity fluidly connected to the outlet port and a second plug operatively connected to the second piston diaphragm. The second pressure cavity is fluidly connected to the linking chamber when the second plug is in an open position.
