Micro Pressure Reducing Regulating Valve

The micro pressure reducing regulating valve adopts a single-stage diaphragm pressure reducing structure and uses rubber or PTFE diaphragms for pressure transmission. It is designed specifically for micro pressure applications, with stable output pressure. It is mainly used in small flow, medium flow gas and liquid systems. It can also be used as a nitrogen seal valve at the top of a storage tank to keep the gas pressure inside the tank stable and within a safe range, usually in conjunction with a nitrogen vent valve.
