The pneumatic diaphragm low-temperature regulating valve is composed of a pneumatic diaphragm actuator and a low-temperature resistant single-seat and double-seat valve. It uses an extended upper valve cover, so although the temperature inside the valve body is very low, the packing on the upper end is still working at room temperature. This product is suitable for regulating media (such as liquid oxygen, liquid nitrogen, etc.) at low temperatures of -60~-250℃. To ensure the regulation accuracy, a valve positioner must be used.
