ANSI 150LB 316 stainless steel Cast iron PN16 Rising Stem soft seal Flanged Gate Valve
Advantages of gate valves
1. Low fluid resistance: Because the internal medium channel of the gate valve body is straight, the medium does not change its flow direction when it flows through the gate valve, so the fluid resistance is small.
2. The opening and closing torque is small, and the opening and closing are more labor-saving: When the gate valve is opened and closed, the direction of movement of the gate plate is perpendicular to the direction of medium flow, and the opening and closing of the gate valve is more labor-saving compared with the globe valve.
3. The flow direction of the medium is not restricted: The gate valve can flow from any direction on both sides, which can achieve the purpose of use, and is suitable for the pipeline where the flow direction of the medium may change.
4. The structure length is shorter: The gate valve gate is vertically placed in the valve body, and the structural length is shorter than that of the globe valve.
5. Good sealing performance: The sealing surface is less eroded when fully opened, and it is suitable for various media.
6. Wide range of application: The body shape is relatively simple, the casting process is good, and it is suitable for large-diameter pipelines.
Gate valve application field
1.Chemical industry: Gate valves are widely used in the piping system of various corrosive media, such as acid, alkali, salt, etc.
2.Petroleum industry: Gate valves are widely used in oil pipelines, oil production platforms and oil refining equipment.
3.Power industry: Gate valves are widely used in steam pipelines, water supply systems and condensate systems.
4.Paper industry: Gate valves are widely used in pulp pipelines, paper machine water and lye systems, etc.
5.Food industry: Gate valves are widely used in food production processes such as beverages, beer, and dairy products.
