China Sluice Valve DINF5 Rising Shaft Type with EPDM Seal - Reliable Suppliers & Factory Direct Offer
| 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
❓
What is a rising stem gate valve and how does it differ from a non-rising stem gate valve?
A rising stem gate valve features a valve stem that moves upward visibly when the valve is opened, allowing operators to immediately determine the valve's open or closed position by visual inspection. In contrast, a non-rising stem gate valve has a stem that rotates in place without moving vertically, making it more suitable for confined or underground spaces. The rising stem design offers better fault visibility and easier maintenance.
❓
What materials are used in this rising stem gate valve?
This rising stem gate valve features a ductile iron body combined with an EPDM (Ethylene Propylene Diene Monomer) resilient seat. The body is manufactured using investment casting for precise dimensions and smooth surfaces. The EPDM seat provides excellent sealing performance and resistance to water, steam, and mild chemicals within the specified temperature range.
❓
What is the operating temperature range for this valve?
This valve is designed to operate within a temperature range of -20°C to 120°C. It is suitable for most standard water supply, drainage, and cooling water applications. For media or environments exceeding this range, please consult with our technical team to select an appropriate alternative.
❓
How should the rising stem gate valve be maintained regularly?
Regular maintenance includes checking the packing box for any signs of medium leakage — if leakage is detected, tighten the packing gland bolts as needed. Inspect the valve stem for signs of bending, corrosion, or obstruction. If the sealing surface is severely worn, replace the gate seal promptly to ensure zero-leakage performance is maintained. Periodic lubrication of the valve stem thread is also recommended to ensure smooth operation.
❓
What are the typical application scenarios for this rising stem gate valve?
This valve is ideal for indoor piping systems in environments such as shopping malls, hospitals, and commercial buildings where dust and moisture are controlled. It is also well-suited for neutral fluid conveying pipelines handling pure water, cooling water, and similar non-corrosive media. Its exposed stem design makes it especially valuable in fire water systems and emergency water supply pipelines where fast visual status confirmation is critical.
❓
What standard does this valve comply with, and how is it packaged for export?
This rising stem gate valve complies with the DIN F5 standard, ensuring compatibility with European and international pipeline systems. For export, the valve is packaged in standard wooden cases designed to protect the product during long-distance shipping, preventing damage from impact, moisture, and vibration during transit.
