There are angle valves capable of reducing pressure for both high-temperature to low-temperature applications and high-pressure to low-pressure applications; the principle of pressure reduction and the structure of these angle valves
That’s because the back pressure at low temperatures is low; it’s not that the angle valve has a pressure-reducing function. For example, the pressure in the device for discharging cold, low-temperature acidic water is also low
It should be by changing the flow cross-sectional area, thereby increasing resistance losses in order to reduce pressure; generally, this involves lower inlet pressure and higher outlet pressure
The valve core of a corner valve differs from that of a regular control valve, as it features multiple stages of pressure reduction
