As a leading supplier and factory in China, we proudly present our ductile iron rising stem gate valve. This high-quality valve features a unique lifting stem design, connecting the valve stem and gate through durable threads. By rotating the handwheel, the valve stem moves up and down seamlessly with the gate, ensuring precise control of flow. The length of the exposed stem section changes in accordance with the valve's opening degree, providing optimal functionality and performance for various applications. Trust our expertise as a reliable China supplier for your gate valve needs.

Key Advantages

👁️ Intuitive Status Monitoring

The valve stem is exposed and moves synchronously with the gate. Operators can immediately determine the valve's opening degree by the length of the exposed stem. This visualization significantly improves inspection efficiency and prevents misjudgment of flow status during emergency operations.

🔧 Simplified Maintenance

Key components like the valve stem and packing box are fully accessible. Daily maintenance does not require disassembling the valve body. If leakage occurs, tightening the gland bolts or replacing the packing is straightforward, leading to shorter downtime and lower maintenance costs.

Frequently Asked Questions

Q: What is the temperature range for this rising stem gate valve?
This valve is designed to operate reliably within a temperature range of -20°C to 120°C, making it suitable for HVAC systems and industrial fire water pipelines.
Q: Can this valve be installed in both horizontal and vertical orientations?
Yes. Due to its bidirectional sealing structure, it can be installed horizontally or vertically. For vertical pipes, we recommend the handwheel faces upward for better accessibility.
Q: How can I visually confirm if the valve is open or closed?
The valve stem acts as a visual indicator; it extends to its maximum length when fully open and retracts to its shortest position when fully closed.
Q: What materials are used for the valve body and seat?
The valve body is constructed from high-quality ductile iron, and the resilient seat is made of EPDM, ensuring zero leakage and long-term durability.
Q: Is it difficult to maintain the valve if a leak occurs at the packing?
No, maintenance is simple. The packing gland is exposed, so you can tighten the bolts or replace the packing directly without needing to disassemble the entire valve body.
Q: What standards do these valves comply with?
These valves are manufactured in accordance with the DIN F5 standard, ensuring compatibility and reliability for international engineering requirements.
