1. The valve body has two structures: casting and welding.
2. Its opening and closing force is small, and it is easy to operate, which is suitable for occasions that require frequent opening and closing.
3. Strong impact resistance: Due to the design of the structure, it can withstand high impact and fluid load, and is suitable for high-pressure systems.
4. Tight sealing performance: The flat gate valve without diversion holes has good sealing performance, and usually uses a flexible sealing ring to contact the gate, which can provide reliable sealing performance under high pressure or high temperature environment.
