The use of soft seal gate 1. Soft seal gate valve opening and closing direction of operation, should be closed clockwise. 2. In order to facilitate a person's opening and closing operations, under plumbing conditions, the maximum opening and closing torque should be 240N-m. 3. Due to the pneumatic valve in the pipe network, often manual opening and closing, opening and closing speed should not be too much, that is, large-diameter valves should also be within 200-600 turn. 4. If the soft seal gate valve buried deeper, the operating mechanism and the display panel from the ground distance ≥ 1.5m, should be equipped with additional rod facilities, and fixed firmly, so that people from the ground to observe and operate.
