Handwheel Gate Valves

Hanno Valve durable ‌Handwheel Gate Valves Installation and use

Before installation, it is necessary to check the valve chamber and sealing surface to ensure that there are no dirt or sand particles attached; 2. The bolts at each connection point should be tightened evenly; 3. Check that the filling part is tightly pressed to ensure both the sealing of the filling and the flexibility of the gate opening; Before installing the valve, users must verify the valve model, connection size, and pay attention to the flow direction of the medium to ensure consistency with the valve requirements; 5. When installing valves, users must reserve necessary space for valve actuation; 6. The wiring of the driving device must be carried out according to the circuit diagram; 7. Gate valves must be regularly maintained and not collided or squeezed at will to avoid affecting the sealing.

Hanno Valve durable ‌Handwheel Gate Valves Operation method

1.Gate valves are only used for fully opening and fully closing various pipelines or equipment for the operation of media, and are not allowed to be used for throttling.

2.Gate valves with handwheels or handles should not be operated with additional auxiliary bars (if the seal is not tight, the sealing surface and other parts should be inspected and repaired). Rotate the handwheel and handle clockwise to close, and vice versa to open. Gate valves with transmission mechanisms should be used according to the instructions in the product manual.

Installation and maintenance

1. Handwheels, handles, and transmission mechanisms are not allowed to be used for lifting and collisions are strictly prohibited.

2. Double gate valves should be installed vertically (i.e. with the valve stem in a vertical position and the handwheel at the top).

3. Before opening a gate valve with a bypass valve, the bypass valve should be opened first (to balance the pressure difference between the inlet and outlet and reduce the opening force).

4. Install gate valves with transmission mechanisms according to the product manual.

If the valve is frequently opened and closed, lubricate it at least once a month.
