Product Details:
V230/V231 D12/D13Self operated pressure regulating valve
V230/V231 D12/D13 self operated pressure regulating valve (commander operated type), consisting of regulating valve, actuator, and commander, 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 (maximum temperature 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.
