ABSTRACT:
A large diameter low pressure collapsible pin relief valve adapted to be connected with a vessel containing fluid under low working pressure is formed by a normally closed valve initially released to open by excess fluid pressure in the vessel applied through telescoping valve stems to a diaphragm opposite the valve for releasing a latch in the telescoping stems and collapsing the pin. Springs connected with the valve move it to full open position.
