Resilient Seat Gate Valve
01
Rising stem gate valve ductile iron body and EPDM Seat
| 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
1. Intuitive opening and closing status:
On site inspection personnel can quickly determine the valve opening without the need for additional tools, resulting in high efficiency in debugging and troubleshooting.
2. Convenient maintenance:
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.
3. Low flow resistance:
When fully opened, the gate completely exits the flow channel, allowing the medium to pass through in a straight line with low energy consumption.
Packing
Standard export wooden case packaging
Application Scenarios
The rising stem gate valve is suitable for scenarios that require frequent inspection and adjustment of opening, making it easy for maintenance personnel to quickly determine the valve's opening and closing status and adjust the flow rate in a timely manner.
