V231 D12、 13 Self operated pressure regulating valve

The commander operated self operated pressure regulating valve consists of a control valve, an actuator, and a commander. It is an energy-saving product that does not require external energy and relies on the pressure changes of the regulated medium to automatically regulate pressure. It can be used as a pressure control device for non corrosive (up to 300 ℃) 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.
