Cf8 / Cf3 Cryogenic Check Valve Straight Through Butterfly Check Valve

 

Good quality OEM CF8/CF3 DN10 to DN250 cryogenic check valve for LNG

 

Cryogenic check valve is a check valve that slides along the vertical centerline of the valve body. The internally threaded check valve can only be installed on horizontal pipelines. On high-pressure small-diameter check valves, the ball can be a ball. The body shape of butterfly check valve is the same as that of globe valve (can be used with globe valve), so its fluid resistance coefficient is large. Its structure is similar to a globe valve, with the same body and disc as the globe valve. The upper part of the valve disc and the lower part of the valve cover are processed with a guide sleeve. The valve disc guide can be freely raised and lowered in the valve guide. When the medium flows, the valve disc is opened by the thrust of the medium. When the medium stops flowing, the valve disc is closed by itself. Falling down on the valve seat, it plays a role in preventing the medium from flowing backward. The direction of the medium inlet and outlet channels of the straight-through butterfly check valve is perpendicular to the direction of the valve seat channel; the vertical lift check valve has the same direction of medium inlet and outlet channels as the valve seat channel, and its flow resistance is smaller than that of the straight type.

 

 

Structure description
 

During the use of this valve, the medium flows in the direction of the arrow shown in the figure.

1. When the medium flows in the prescribed direction, the valve disc is opened by the force of the medium; when the medium is flowing backward, the valve disc is tightly sealed with the valve seat due to the weight of the valve disc and the reverse force of the medium Closed together to achieve the purpose of preventing the medium from flowing back.

 

2. The sealing surfaces of the valve body and disc are made of stainless steel.

 

3. The structural length of this valve is in accordance with GB12221-1989, and the flange connection size is in accordance with JB / T79-1994.

Notes When Use

1. It should ensure that the pipe is blown clean before installation.


2. When installing, make sure that the flow direction indicated by the arrow on the valve body should be consistent with the flow direction of the fluid.


3. This valve has been degreased. Store and keep clean when installing.


4. After the pipeline construction is completed, all the valves on the pipeline should be opened, and the residue in the pipeline should be thoroughly and thoroughly kept to ensure that the pipeline system is clean and free of debris.


5. The installation system diagram with the oil-free requirements should be degreased.


6. Slowly open and close during use.


7. If the precision parts such as the valve disc, valve seat and valve stem are worn or damaged, it must be repaired and replaced in time.


8. For parts such as gaskets and sealing materials, replace them with new ones each time.
