1. The output pressure and total flow are different
Among them, the output pressure of the high-pressure valve is high, and the total flow rate is also high, and its pressure will increase the screw-in pressure of the mold thimble and reduce the screw-out pressure. The low-pressure valve has a small output pressure and a small total flow, which can control the pressure of the liquefied gas tank and release the gas little by little.
2. The main uses are different
The high-pressure valve is generally used on the side of high-power gas stoves such as hotel restaurants, restaurants, and canteens. Low-pressure valves are generally used on the side of gas stoves or electric water heaters at home.
3. The security level is different
The high-pressure valve has high pressure and a fast flow speed. In the case of no fire, liquefied gas is very easy to be released into the air to cause engineering blasting. The low-pressure valve has low pressure and slow flow speed, which can control the pressure and release the gas little by little. Even if the maintenance screw falls off during application, the released gas will not be very large.
