Principle of gas booster valve: using compressed air as a power source, without any power supply can be pressurized gas, gas pressure can be increased by several times to dozens of times, by adjusting the pressure of the drive gas can be obtained by the required pressure, when the gas pressure reaches the set value, the booster pump automatically stops working in order to save energy, with the high pressure of the gas consumption, the booster pump and automatically start working. The pressurizing valve is included in the selection of Fast and Easy Automation, which utilizes the low-pressure gas drive at the large-area piston end to generate the high-pressure gas at the small-area piston end. Automatic restart work, the gas booster quickly reciprocating work, with the output pressure close to the set pressure value when the pump reciprocating movement slows down until it stops. And maintain this pressure, this time the energy consumption is very small, no heat generation, no parts movement. When the pressure balance is broken, the booster automatically start working to the next balance.
