Employing a lifting stem configuration, the ductile iron rising stem gate valve uses threaded connections to link the valve stem and gate. As the handwheel is turned, the valve stem elevates or lowers in tandem with the gate, and the exposed stem length directly reflects the valveâ€™s opening status for easy visual inspection.

Product Description

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.

Key Advantages

✔

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. During debugging, the valve stem lifting distance can be observed to accurately set the stroke, ensuring the sealing surface is perfectly in place.

✔

Timely fault warning and high safety

The exposed design of the valve stem facilitates real-time monitoring. If the valve stem is bent, corroded, or the packing is leaking, it can be detected immediately, avoiding small faults from evolving into serious accidents. This is critical for fire water systems and emergency pipelines.

Packing Details

We utilize standard export wooden case packaging to ensure the safety of the valves during international transit.

Application Scenarios

The rising stem gate valve is suitable for dry and low corrosion environments, indoor piping systems (such as water supply and drainage pipes in shopping malls and hospitals), and neutral fluid conveying pipelines (pure water, cooling water).

Frequently Asked Questions

Q1: What is the main advantage of a rising stem gate valve?

The primary advantage is the visible stem, which allows operators to easily determine if the valve is open or closed and monitor the condition of the stem for maintenance.

Q2: What standards does this gate valve comply with?

This valve is designed according to the DIN F5 standard, ensuring interchangeability and high-quality performance in international piping systems.

Q3: Can this valve be used for hot water systems?

Yes, the valve is rated for temperatures up to 120°C, making it suitable for hot water and various neutral fluid cooling systems.

Q4: How do I handle leaks in the packing box?

If medium leakage occurs at the packing box, you can simply tighten the packing gland bolts. If the leak persists, the seal may need to be replaced.

Q5: Which seal materials are available?

We provide high-quality resilient seals made from NBR or EPDM, depending on your specific medium and temperature requirements.

Q6: Are these valves suitable for underground installation?

Rising stem valves are generally preferred for exposed or indoor installation due to the stem movement. For underground use, non-rising stem valves are typically used unless a pit is provided.
