Overview
The all stainless steel 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 is widely used in pressure control devices for corrosive liquids, gases, steam and other media. Applied to industrial sectors such as petroleum, chemical, and metallurgical industries.
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.
