Note

1. The handwheel, handle, and other actuation mechanisms should not be used as lifting tools (for details, see the product manual).

2. The double flange gate valve should be installed vertically (the handwheel should be at the top, and the handwheel should be removed).

3. The gate valve with bypass valve should be opened before opening the main valve (to balance the pressure difference before opening the main valve).

4. When used with a motor actuator, follow the manufacturer's instructions for installation.

5. If the gate valve is not opened and closed frequently, apply lubricant regularly.
