Wholesale China Rising Stem Gate Valve - Ductile Iron Body with EPDM Seat | Suppliers & Factory Options Available Suppliers, Factory
Product Description
| Valve Type: | Resilient seat gate valve | Structure: | Non-rising type |
| Standard: | DIN F4 | 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
On site inspection personnel can quickly determine the valve opening without the need for additional tools, resulting in high efficiency in debugging and troubleshooting.
The valve stem is exposed, making it easy to inspect for wear and corrosion. It is also easy to replace the packing or repair the valve stem.
When fully opened, the gate completely exits the flow channel, allowing the medium to pass through in a straight line with low energy consumption.

❓ Frequently Asked Questions
A resilient seat gate valve features a rubber-coated gate (typically EPDM) that provides a tight, zero-leakage seal on both sides. Unlike standard metal-seated gate valves, it achieves a better seal at lower operating torques and is more resistant to minor debris in the pipeline, making it ideal for water supply and distribution systems.
Bidirectional sealing means the valve can effectively block and seal the flow of media from either direction — whether the pressure is applied from upstream or downstream. This provides greater installation flexibility, as there is no need to pay attention to the flow direction when installing the valve in the pipeline.
A rising stem gate valve has a visible stem that moves upward when the valve is opened, allowing operators to immediately and visually identify whether the valve is open or closed without any additional tools. A non-rising stem valve keeps the stem stationary while only the gate moves internally, making it more suitable for locations with limited vertical space.
This valve can be installed both horizontally and vertically, as the bidirectional sealing structure does not restrict the flow direction of the medium. However, when installed vertically, it is recommended to orient the handwheel facing upward to ensure convenient and safe operation by maintenance personnel.
This resilient seat gate valve is designed to operate within a temperature range of -20°C to 120°C. This range makes it suitable for most standard water supply, HVAC, and industrial fluid control applications. Operating beyond these temperature limits may affect the sealing performance and service life of the valve.
The valve is packaged in standard export wooden cases, which provide robust protection against impact, moisture, and mechanical damage during international shipping. The valve is manufactured to the DIN F4 standard, ensuring compatibility with internationally recognized pipeline systems and flanged connections.
