Install and use step 1. Before the installation must check valve cavity and seal face and other parts, there is no dirt or sand clinging to the body; 2. Each bolt connection parts, require uniform tight; 3. Check the packing pressure parts requirements, both to ensure that the packing sealing, also to ensure the gate open flexible; 4. Users must before installing the valve, check Industrial Valves, connected to the flow direction of medium size and note, ensure consistency with the Industrial Valves requirements; 5. User when installing the valve, the valve must be set aside driven necessary space; 6. Drive connection must be according to the circuit diagram; 7.
