SP439 Self-Operated Micro-Pressure Regulating Valve

SP 439 is a Spring Driven- Self-Operated Micro-Pressure Regulating Valve. Suitable for various types of low corrosive gases. It can reduce and stabilize high-pressure gas to the extreme low pressure. It is only used for downstream pressure control. It is also used for micro-pressure control of different gases, especially applied to the nitrogen blanketing system. The minimum control pressure is 0.3Kpa. The maximum control pressure is 15Kpa. The minimum operation temperature is -48℃ and the highest operating temperature is 120℃.
