ANSI 150LB PN16 ductile iron resilient seat cast iron gate valve
Functional characteristics of the valve body
1. Good sealing performance: The gate valve has good sealing performance, which can maintain small medium erosion in the fully open state to ensure the tightness of the system.
2. Low fluid resistance: The design of the gate valve makes the resistance encountered by the fluid when passing through small, which is conducive to improving the flow efficiency of the fluid.
3. Labor-saving opening and closing: Compared with some valves, the opening and closing operation of the gate valve is more labor-saving, which is convenient for the operator to operate.
4. Wide range of adaptation: Gate valve is suitable for a variety of media, including water flow, steam, oil and oxidizing media, etc., and is not limited by the flow direction.
5. Simple structure and low manufacturing cost: The structure of the gate valve is relatively simple, the manufacturing cost is low, and it is convenient for large-scale production and maintenance.
Installation precautions
1. The handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.
2. The double gate valve should be installed vertically (that is, the valve stem is in a vertical position and the handwheel is at the top).
3. The gate valve with bypass valve should be opened before opening (to balance the pressure difference between the inlet and outlet and reduce the opening force).
4. The gate valve with the transmission mechanism shall be installed according to the provisions of the product instruction manual.
5. If the valve is often opened and closed, lubricate it at least once a month.
6. The gate valve is only used for the operation of the medium on all kinds of pipelines or equipment that is fully open and closed, and is not allowed to be used for throttling.
7. For gate valves with handwheels or handles, no auxiliary levers shall be added during operation (if the sealing is not tight, the sealing surface or other parts should be checked and repaired). The handwheel and handle rotate clockwise to close, and vice versa. The gate valve with the transmission mechanism should be used in accordance with the provisions of the product instruction manual.
