316L Rising Stem Gate Valve Z41W
Advantages
1. Extremely low flow resistance. The internal passage of the valve body is straight-through, allowing medium to flow in a straight line with minimal flow loss.
2. Requires less opening/closing force. Compared with globe valves, the movement direction of the gate plate is perpendicular to the medium flow direction during opening and closing operation.
3. High overall height and long operation travel. The gate plate travels a large stroke, with opening and closing driven by the stem screw rotation.
4. Less prone to water hammer, thanks to its long closing time.
5. Medium can flow freely in both directions, allowing for easy installation. The gate channel is symmetrical on both sides.
6. Short structural length (distance between the two end connecting flanges).
7. Simple overall shape, short structural length, excellent manufacturing process, wide range of applications.
8. Compact structure, high valve rigidity, smooth flow passage and low flow resistance. The sealing surface adopts stainless steel and hard alloy overlay, ensuring long service life. Equipped with PTFE packing for reliable sealing and easy operation.
Disadvantages
The sealing surface is prone to erosion and scratches, making maintenance relatively difficult. Large overall dimensions require extra installation space for operation, with long closing time and complex internal structure.
