ZGPV multi-function pressure reducing valve can be used in water, steam, natural gas, oxygen, nitrogen, hydrogen and other media.
ZGPV pressure reducing valve is a kind of energy-saving control device which can automatically adjust the pressure of the regulated medium as the power source and the pressure change of the medium without additional driving energy. It sets many functions of detection, control and execution in one valve, and becomes an independent instrument control system. ZGPV pressure relief valve has the advantages of simple structure, easy operation and less maintenance work. It is especially suitable for urban heating, heating, no external power supply, gas supply and steam pressure control. According to foreign reports, the energy-saving efficiency of urban heating and heating system using this product has increased by 30% - 40% compared with the previous, and the effect is remarkable.
Product features
ZGPV pressure relief valve does not need additional drive energy, energy-saving automatic control system, low equipment costs, suitable for explosive environment; simple structure, maintenance workload is small; set point adjustable and wide range, convenient for users to continuously adjust within the set range; diaphragm-type execution machinery than cylinder-type mechanism detection precision, action sensitive; The pressure balancing mechanism is adopted to make the regulating valve sensitive, precise and allowable.
