Abstract
A pneumatic pressure regulation valve comprising: a valve inlet; a valve outlet; a piston arranged to control gas flow from the inlet to the outlet; a sense line fluidly connecting the inlet to a pressure regulation chamber and with a pressure relief valve connected thereto to limit the pressure in the pressure regulation chamber; wherein the piston is arranged between the pressure regulation chamber and the valve outlet such that the position of the piston is determined by the relative pressures in the regulation chamber and the valve outlet and the position of the piston controls the flow from the valve inlet to the valve outlet; wherein the sense line comprises a flow restriction upstream of the pressure relief valve. The flow restriction addresses instability that can arise from large volumes of connecting tubes or pipes in the sense line.
