The invention discloses a micro-flow high-precision light miniaturized pressure stabilizing valve which comprises a valve body, a valve seat, a membrane assembly, a spring seat, a spring, a valve element, a pressing device, a pressing ring, a main spring seat and an adjusting ball. The valve body and the valve seat form a separating structure, the machining requirements for the valve body and the valve seat are reduced, and machining is easy. The valve seat and the valve element are in a soft-hard sealing mode. No friction is achieved in the working process through clearance fit. The valve seat serves as an independent assembly to be assembled on the valve body, meets the requirement of the matched position between the valve seat and the valve element and improves the reset precision. The membrane assembly is sensitive to pressure and prevents leakage of a working medium, and product performance is improved. The valve element is designed integrally, the part number is decreased, and assembly and machining are easy. Based on the characteristics, the product performance is met, space is saved, and light miniaturization is achieved.
