Ultra Low Temperature Globe Valve
Introduction:
The ultra-low temperature globe valve is composed of valve body, valve disc, valve stem, valve cover, hand wheel and seal. The packing and the lower packing form a double compression sealing structure. The direction of the medium flow channel adopts low in and high out. The inlet channel of the valve body is below the sealing surface of the valve seat, and the outlet channel of the valve body is above the sealing surface of the valve seat. After the system is pre-cooled for the first time, please check the locking status of fasteners such as bolts, nuts and packing caps. If there is a small amount of leakage, it is caused by the shrinkage of the material when it is cold, and the fasteners should be cooled again. It can be tightened down.
