V230 Self operated Pressure Regulating Valve
V230 Self operated Pressure Regulating Valve
Product details
Product Overview
The V230 series self operated pressure regulating valve consists of 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 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.
