BS 4504 Ductile Iron PN10 PN16 DN100 50mm Non Rising Stem NRS Gate Valve For Water
Product Introduction
Soft sealing gate valves, industrial valves, and soft sealing gate valves have gate plates as their opening and closing components. The direction of movement of the gate plate is perpendicular to the direction of the fluid, and the gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.
The gate valve has two sealing surfaces, and the most commonly used mode is that the two sealing surfaces of the gate valve form a wedge shape. The wedge angle varies with the valve parameters, with a nominal diameter of DN50 to DN1200 and a service temperature of ≤ 200 ℃.
Product Advantages
1.Low fluid resistance: The medium channel inside the gate valve is straight, and the medium does not change its flow direction when it flows through, so the fluid resistance is small.
2.Labor-saving opening and closing: The direction of movement of the ram is perpendicular to the direction of medium flow, and it is less labor-saving than other types of valves when opening and closing.
3.The flow direction of the medium is not restricted: The two sides of the gate valve channel are symmetrical, and the medium can flow in any direction from both sides, which is suitable for pipelines where the flow direction of the medium may change.
4.Shorter structure length: The ram is placed vertically in the valve body, which is shorter than some other types of valve structures.
5.Good sealing performance: The sealing surface is less corroded when fully opened, and the sealing performance is better.
6.Suitable for working conditions that do not need to be opened and closed frequently: Gate valves are usually suitable for working conditions that do not need to be opened and closed frequently, and keep the gate fully open or fully closed, which is not suitable for adjustment and throttling.
