Even if all valves are the same, there will be different classifications of marine casting valves. Therefore, when we choose this type of Dalian marine valves, we should pay attention to the classification and application range, so that we can select the appropriate Dalian marine valves. Dalian marine valve manufacturers will introduce several different classifications of these products.

Straight through

This should be a stop valve that we often see in our daily life. The straight through type is easy to install and can be used in many pipes. Basically, I can turn it on and off by turning it 90 degrees, so it's good to use my version.

Direct current type

In fact, this type of high-temperature stop valve is a straight through product, which makes the flow channel of the valve body and the main flow channel form a diagonal line directly. The flow state is less than that of the ordinary straight through type, so the pressure will not be lost so much when passing through the valve.

Angular

Such a shut-off valve changes the direction of the primary fluid, so the overall pressure will be reduced when passing through such a shut-off valve. It is necessary to use such a stop valve at some corner positions, and the practicability is also good.

Plunger type

In fact, this type of high-temperature stop valve is a deformation of the conventional one. The valve disc and valve seat are designed with plunger. Moreover, its sealing performance is stronger, and the sealing rings can be replaced at any time. Sealing rings of different materials can be applied. This type of valve is mainly used for opening and closing, and can also be used for flow regulation, so its practicability and application range are wider.
