Is the check valve a two-way valve?
Check valves are two-way valves, meaning that they have two openings in the valve body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. Although they come in various sizes and costs, check valves are usually very small, simple or cheap.

Setting pressure of safety valve
Set pressure refers to the predetermined pressure when the safety valve disc starts to open under operating conditions. It is the gauge pressure measured at the valve inlet. At this pressure, under the specified operating conditions, the force generated by the medium pressure to open the valve is balanced with the force that keeps the valve flap on the valve. At this pressure, a measurable opening height begins, and the medium assumes a continuous discharge state that can be perceived visually or audibly.
