V230Y type self operated pressure regulating valveDetailed product description：

V230Y regulating valve is composed 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 adjust the 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, V230Y regulating valves are widely used in industrial sectors such as petroleum, chemical, metallurgical, and light industry, as well as urban heating and heating systems. The V230Y regulating valve 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.

The main component materials of V230Y self operated pressure regulating valve are:

valve body	valve core	valve seat	valve stem	Membrane cover	filler	diaphragm
