4.13 Air in a spring loaded piston/cylinder has a pressure that is linear with volume, P. = A + BV. With an initial state of P = 150 kPa, V = 1 L and a final state of 800. kPa and volume 1.5 L it is similar to the setup in Problem 3.16.
In direct acting pressure reducing valves, the amount of valve opening is determined directly by the movement of the adjustment spring. If the spring is compressed, it creates an opening force on the valve which increases flow.ypes of Pressure Reducing Valves for Steam. In pressure reducing valves, the mechanism that automatically adjusts the downstream pressure typically uses the balance of forces between the steam pressure and an adjustment spring. At present, this is a universal concept on almost all manufactured pressure reducing valves.
