KD741X Heavy-weight Pressure-Resisting Butterfly Valve, Pressure-Resisting Butterfly Valve

Features of KD741X Heavy Weight Pressure Holding Butterfly Valve:

1. It can replace the original electric gate valve and check valve at the pump inlet, and integrates the mechanical, electrical and hydraulic systems into one unit, reducing the floor space and infrastructure investment. 2. The heavy weight pressure holding butterfly valve is complete. Without additional configuration, it can be used as an independent system for local debugging and control; or it can be a device unit of a distributed control system (ICS), managed centrally by a central computer through I/O channels, achieving coordinated operation with pumps, water turbines, bypass valves and other pipeline equipment; it also has a manual function, without power supply.

Originally, it can also achieve manual opening and closing of the valve to meet the requirements of valve debugging and control in special working conditions. 3. It has good controllability, a wide adjustment range and strong adaptability. The electro-hydraulic control system has multiple adjustment points, which can set the opening and closing procedures according to different pipeline control requirements, ensuring that the valve can and only can automatically open and close at the pre-set time and angle when the conditions for opening and closing the valve are met. It can also achieve automatic closing without power supply, effectively eliminating destructive water hammer, preventing runaway accidents of pumps and water turbines, reducing pressure fluctuations in the pipeline system, and ensuring the safe and reliable operation of equipment. 4. The main valve sealing pair is a three-eccentric metal sealing or double eccentric rubber sealing structure, which is easy to open and close and has reliable sealing; and there is an additional enlarged eccentric, making the valve have good self-sealing performance. The butterfly plate of medium and small diameters is designed as a streamlined flat plate structure, and the butterfly plate of large diameter is designed as a double flat plate frame structure, which is compact, the water flow is smooth, and the flow resistance coefficient is 0.1 - 0.6, much smaller than the flow resistance coefficient of the check valve (1.7 - 2.6), with obvious energy-saving effect.

The heavy hammer pressure retaining butterfly valve is complete and does not require additional configuration. It can be used as an independent system for on-site debugging and control by itself. It can also serve as a device unit of the distributed control system (DCS), which is centrally managed by the central computer through I/O channels, and can achieve coordinated operation with pumps, water turbines, bypass valves and other pipeline equipment.

Packing of Standard Packing:
