Pressure regulators have been part of industries to address various requirement related to pressure settings. Being in industry since long time, lot of research's have already been done to address issues & improve performance. The published research papers had addressed the performance issues like cavitation (that happens due to sudden pressure drop causing the bubble formation at localized area which in term results in cavitation), high pressure, high-pressure differential(which is normally achieved by multistage of regulator as single stage regulator cannot work above certain pressure differential), pressure stability (by adding sensitive diaphragm & high precision controlled orifice seat),corrosion (by using high grade NACE complain material like 316L & duplex stainless steel),various failures (like galling, mushroom formation, pitting, diaphragm rupture) & safety (by designing regulator as per various internal standard like PED, ASME BPVC). Ergonomic aspect of pressure regulator considering the human comfort found missing. This paper addresses the ergonomic aspects pressure regulator to ease setting downstream pressure with non-stretching & frictionless material. Research will also address to make pressure regulator setting uniform torque across the pressure range making regulator more sensitive for precise pressure setting. It also addresses the requirement of high flow through controlled orifice by introducing a bypass system working in parallel with controlled regulator to achieve fast volume filling at high pressure.
