China Suppliers Factory Ductile Iron Rising Stem Sluice Valve DINF5 EPDM Seal Resilient Seated DN40-DN600
| Valve Type: | Resilient seat gate valve | Structure: | Rising type |
| Standard: | DIN F5 | Workmanship: | Investment casting |
| Sealing direction: | Bidirectional | Sealing grade: | Zero leakage |
| Temperature: | -20°C<T<120°C | Operation： | Handwheel |
Characteristics
After long-term use, it is necessary to regularly check the sealing performance of the packing box. If there is medium leakage, the packing gland bolts can be tightened; When the sealing surface is severely worn, it is necessary to replace the gate seal in a timely manner.
Advantages
1. Flexible installation and debugging, suitable for exposed pipelines
For scenarios with sufficient space such as overhead open installation and pump room equipment rooms, the lifting structure of the rising stem gate valve will not interfere with surrounding pipelines and equipment, and there is no need to reserve additional concealed space during installation. During the debugging phase, the valve stem lifting distance can be observed to accurately set the opening and closing stroke of the valve, ensuring that the sealing surface is in place and avoiding sealing failure caused by improper stroke.
2. Timely fault warning and high safety
The exposed design of the valve stem facilitates real-time monitoring of its operating status: if the valve stem is bent, corroded, blocked, or the packing is aging and leaking, it can be detected and dealt with in a timely manner, avoiding small faults from evolving into serious accidents where the valve cannot be opened or closed. This advantage is particularly important in scenarios with high safety requirements such as fire water systems and emergency water supply pipelines.
Packing
Standard export wooden case packaging
Application Scenarios
The rising stem gate valve are suitable for dry and low corrosion environments, indoor piping systems (such as water supply and drainage pipes in shopping malls and hospitals), valve stems are not easily corroded by dust and water vapor, reducing maintenance frequency; Neutral fluid conveying pipelines (such as pure water, cooling water), without corrosive media affecting the valve stem life.
Frequently Asked Questions (FAQ)
What standard does this resilient seat gate valve comply with?
This resilient seat gate valve complies with the DIN F5 standard, featuring a rising structure, investment casting workmanship, and bidirectional sealing for zero leakage.
What is the working temperature range of the rising stem gate valve?
The valve is designed to operate safely within a temperature range of -20°C to 120°C (-20°C < T < 120°C).
What are the main advantages of using a rising stem structure?
It allows flexible installation and debugging in exposed pipelines. The exposed stem also functions as a visual indicator for open/closed positions and helps in timely fault warnings such as stem bending or packing leaks.
How should the packing box be maintained?
Regularly check the sealing performance of the packing box. If there is medium leakage, tighten the packing gland bolts. Replace the gate seal promptly if the sealing surface is severely worn.
What are the typical application scenarios for this valve?
It is ideal for dry, low-corrosion environments, indoor piping systems (such as in hospitals and shopping malls), and neutral fluid conveying pipelines like cooling water and pure water.
What packaging is used for shipping?
Standard export wooden case packaging is used to ensure safe transport and prevent damage to the valve stem and body.
