Product details

V230Y type self operated pressure regulating valve

Product Details:
The V230Y self operated pressure regulating valve consists of a valve body, valve seat, valve core components, etc. It is an energy-saving product that does not require external energy and relies solely on the pressure changes of the regulated medium to automatically regulate pressure. It can be used as a pressure control device for non corrosive liquids, gases, steam and other media. Compared with ZZYP, the control spring is less affected by medium temperature due to its distance from the valve body, and is easier to replace or adjust Therefore, it is 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. It has a larger pressure difference range than the old model.
Main component materials
Valve body: ZG230-450, ZG1Cr18Ni9Ti, ZGCr18Ni12Mo2Ti Valve core: 1Cr18Ni9Ti, Cr18Ni12Mo2Ti Valve seat: 1Cr18Ni9Ti, Cr18Ni12Mo2Ti Valve stem: 1Cr18Ni9Ti, Cr18Ni12Mo2Ti Membrane cover: A3, 1Cr18Ni9Ti Packing: polytetrafluoroethylene, flexible graphite membrane: nitrile rubber, oil resistant rubber, fluororubber
