Cryogenic Globe Valve Extended Bonnet for -196℃
✧ Description
Cryogenic Globe Valve with Extended Bonnet used for -196℃, widely used in chemical industry, petroleum, natural gas, metallurgy, electric power and other industries. The forged steel globe valve adopts a fully welded structure, and the valve body and gate are made of forged steel parts. The valve has good sealing performance, strong corrosion resistance and long service life. Its structure is simple, small in size, easy to install and maintain. The gate switch is flexible and can completely cut off the medium flow without leakage. The forged steel globe valve has a wide temperature range and high working pressure, and can be used for medium flow control under high temperature and high pressure and low temperature and high pressure conditions.
✧ Features of API 602 Cryogenic Globe Valve Extended Bonnet for -196℃
1.The structure is simpler than the globe valve, and it is more convenient to manufacture and maintain.
2.The sealing surface is not easy to wear and scratch, and the sealing performance is good. There is no relative sliding between the valve disc and the sealing surface of the valve body when opening and closing, so the wear and scratch are not serious, the sealing performance is good, and the service life is long.
3.When opening and closing, the stroke of the disc is small, so the height of the stop valve is smaller than that of the globe valve, but the structural length is longer than that of the globe valve.
4.The opening and closing torque is large, the opening and closing is laborious, and the opening and closing time is long.
5.The fluid resistance is large, because the medium channel in the valve body is tortuous, the fluid resistance is large, and the power consumption is large.
6.Medium flow direction When the nominal pressure PN ≤ 16MPa, it generally adopts forward flow, and the medium flows upward from the bottom of the valve disc; when the nominal pressure PN ≥ 20MPa, generally adopts counter flow, and the medium flows downward from the top of the valve disc. To increase the performance of the seal. When in use, the globe valve medium can only flow in one direction, and the flow direction cannot be changed.
7.The disc is often eroded when fully open.
✧ Advantages of API 602 forged steel globe valve
During the opening and closing process of the forged steel globe valve, because the friction between the disc and the sealing surface of the valve body is smaller than that of the globe valve, it is wear-resistant.
The opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for the adjustment of the flow rate. Therefore, this type of valve is very suitable for cut-off or regulation and throttling.
