China Suppliers Factory DINF5 Rising Shaft Resilient Sealing Gate Valve - Z41X Series, DN40-DN600, PN6-PN25
| Valve Type: | Resilient seat gate valve | Structure: | Non-rising type |
| Standard: | DIN F5 | Workmanship: | Investment casting |
| Sealing Direction: | Bidirectional | Sealing Grade: | Zero leakage |
| Temperature: | -20°C < T < 120°C | Operation: | Handwheel |
Characteristics
This valve has a bidirectional sealing structure, which can be installed horizontally or vertically, and the flow direction of the medium is not restricted; When installed vertically, it is recommended to have the handwheel facing upwards for easy operation.
Advantages
👁️
1. The opening and closing status is intuitive and controllable, with high inspection efficiency
The valve stem is exposed and rises and falls synchronously with the gate. The operator can directly determine the valve opening degree by the length of the exposed valve stem (the valve stem extends the longest when fully open and the shortest when fully closed), without the need for additional opening indicators or instrument detection. This visualization feature greatly improves the efficiency of on-site inspections, especially suitable for working conditions that require frequent debugging and emergency operations. It can effectively avoid insufficient flow or abnormal system pressure caused by misjudging the opening degree.

2. Convenient maintenance and reduced maintenance costs
The key components such as the valve stem and packing box are exposed, and during daily maintenance, there is no need to disassemble the valve body to directly inspect the wear and corrosion of the valve stem, as well as the sealing performance of the packing. If there is medium leakage, simply tighten the packing gland bolts or replace the packing; When the valve stem becomes stuck, it can be directly lubricated, calibrated, or replaced. Compared to the disassembly repair of the valve body of the concealed stem gate valve, the process is simpler, the downtime is shorter, and the maintenance cost is lower.

Frequently Asked Questions
Q
What is the temperature range for this rising stem gate valve?
This valve is designed to operate within a temperature range of -20°C to 120°C, making it suitable for a wide range of industrial and commercial applications including HVAC systems and fire water pipelines.
Q
Can this valve be installed in both horizontal and vertical orientations?
Yes, thanks to its bidirectional sealing structure, the valve can be installed either horizontally or vertically without restriction on the flow direction of the medium. When installed vertically, it is recommended to position the handwheel facing upwards for easier operation.
Q
How can I tell whether the valve is fully open or fully closed?
The exposed valve stem provides a direct visual indication of the valve's status. When the valve is fully open, the stem extends to its longest position; when fully closed, it is at its shortest. No additional indicators or instruments are required.
Q
What standard does this gate valve comply with, and what is its body material?
This gate valve complies with DIN F5 standard. The valve body is made of ductile iron, and the seat is made of EPDM material, ensuring long-term durability and reliable sealing performance.
Q
What should I do if there is medium leakage from the packing area?
If medium leakage occurs at the packing area, you can simply tighten the packing gland bolts as a first step. If the leakage persists, the packing can be replaced directly without disassembling the valve body, minimizing downtime and maintenance costs.
Q
What are the typical application scenarios for this rising stem gate valve?
This valve is widely used in HVAC cold and hot water circulation exposed pipelines, as well as fire water system exposed main pipelines in industrial plants and commercial buildings, where visibility of valve status and ease of maintenance are important.
