ZGPV multifunctional pressure reducing valve can be used for media such as water, steam, natural gas, oxygen, nitrogen, hydrogen, etc. ZGPV pressure reducing valve is an energy-saving control device that does not require external driving energy, relies on the pressure of the regulated medium itself as the power source and its medium pressure changes, and automatically adjusts according to the predetermined set value. It integrates detection, control, and execution functions into one valve, forming an independent instrument control system. ZGPV pressure reducing valve is particularly suitable for urban heating, heating, and situations where there is no external power supply or gas supply, and steam pressure control is required due to its advantages of no external energy source, simple structure, convenient use, and low maintenance workload. According to foreign reports, the use of this product in urban heating and heating systems has significantly improved energy efficiency by 30% -40% compared to before.
