How do bellows valves work?
Bellow is similar to a hollow flexible hose. It functions like a vertical diaphragm (parallel instead of perpendicular to valve stem). It seals with the valve stem at one end, and seals with the valve body at the other end. Therefore, it allows a small relative move between valve stem and body, but prevents fluid from leaking across bellow surface. The move pushes seat or stem tip for valve to close or open. --SteveX

What is blow down pressure of safety valve?
the blowback or blowdown of the safety valve is at least 2 psi and for pressures over 100 psig is 2% of the popping pressure. The blowback is adjusted with the adjusting ring on the safety valve. The blowback is the pressure less than the popping pressure at which the safety valve will reset. Examples: a safety valve set to pop at 15 psig will reseat at 13 psig, the blowback is 2 psi. A safety valve set to pop at 250 psig will reseat at 245 psig the blowback is 5 psi or 2%.
