Abstract: A pressure retaining valve adapted to retain correctly any predetermined pressure of any fluid and serve as a safety valve which discharge the fluid to the second side for counter balance when the pressure of the fluid at the first side exceeds the predetermined pressure. The valve comprises a valve casing having an inlet and an outlet for fluid, a vertically disposed axial bore having stepped portions, and an uniquely shaped valve body fitted in the vertical bore, an adjustable spring loaded cylindrical member installed beneath the casing and connected to the vertical bore.
