V230,V231 series self operated pressure regulating valveDetailed product description：

The V230 and V231 series self operated pressure regulating valves are direct acting self operated pressure (differential pressure) regulating valves composed of valve body, valve seat, valve core components, and other parts. They are energy-saving products that do not require external energy and rely solely on the pressure changes of the regulated medium to automatically regulate pressure. They can be used as pressure control devices for non corrosive (up to 350 ℃) liquids, gases, steam and other media. Widely applicable to industrial sectors such as petroleum, chemical, metallurgical, and light industry, as well as urban heating and heating systems.
