Regarding the gas pressure control valve for vehicles
Thread Content
I would like to ask the experts in the chemical industry to explain the function of the gas pressure control valve during startup. Is this valve used only during startup? :handshake
The original poster isn’t very clear about their intent; it would be better if they could explain things in more detail.
Reply to 2# GSP: I also have very limited information; the tag numbers are PV-606A/B, with a pressure of 3.9 MpaG before the valve and 0.01 MpaG after it.
Reply to 4# sxwzq: That’s right, it’s this back pressure valve – the pressure that is set.
A valve that raises the pressure in the system after feeding at atmospheric pressure. After the pressure returns to normal, direct air to the rear system.
