How
Relief valve opens stem when the pressure exceeds a set pressure and closes when the pressure falls below.
WHERE
To protect the equipment form the over pressure. In the system which control the overpressure by heat expansion. When the low drain rates is not the problem point in high pressure. When the system requires “bubble tight’ sealing.
WHERE NOT
Pressure ~ below 1,000psi. If the system requires to increase venting or drain rates when the pressure rises. If the back pressure occurs at the drain port. High corrosive fluids, liquid N2 or any other fluids that defect the valves.
