Product details

  • Product Details:

    　　V230D01Type self operated pressure regulating valveIt is an energy-saving product composed of valve body, valve seat, valve core components, etc. It does not require external energy and relies solely on the pressure changes of the regulated medium to automatically adjust the pressure. It can be used as a pressure control device for non corrosive liquids, gases, steam and other media. Widely used in industrial sectors such as petroleum, chemical, metallurgical, and light industry, as well as urban heating and heating systems.
    This product has a nominal pressure of PN16 and 40, a nominal diameter range of 20-300mm, and an operating temperature of ≤ 350 ℃. There are a variety of varieties to choose from.
