Hydraulic Check Butterfly Valve

The hydraulic control check butterfly valve designed by Dazhong Valve Group has a complete hydraulic system and electrical control system. The main sealing pair of the valve adopts triple eccentric metal seal or double eccentric rubber sealing structure. Adjustment screw for seal compensation adjustment. The bearings are lead-free and oil-free self-lubricating bearings. The valve has a wide adjustment range, strong adaptability and good controllability.

• The hydraulic control check butterfly valve is widely used in the pump outlet of various pump stations such as water conservancy, electric power, water supply and drainage, etc. It has the functions of gate valve and check valve. According to the principle of hydraulic excess process, through pre-set procedures, It is closed in two stages (first close a certain angle quickly, and then slowly close the remaining angle) to achieve a reliable cut-off of the pipeline, which is an ideal device to protect the safety of the pipeline system.

• The butterfly valve has a high degree of automation, complete functions and stable and reliable performance. It is the result of many scientific research achievements of our company's designers in the valve, hydraulic, electrical and other industries. A new generation of high-efficiency, energy-saving and intelligent products developed on the basis of.

• The valve has a complete hydraulic system and electrical control system, which can be operated both locally and remotely. The main seal pair of the valve adopts triple eccentric metal seal or double eccentric rubber seal structure, and the opening and closing torque is small , has good self-closing, self-sealing performance, reliable sealing, stable and reliable performance.

• After the rubber seal is worn, the seal compensation can be adjusted through the adjusting screw on the butterfly plate. The bearing adopts lead-free self-lubricating bearing without oil supply, which has strong bearing capacity and good wear resistance.

• The valve has a wide range of adjustment, strong adaptability and good controllability. The hydraulic and electrical control part has multiple adjustment points, and the opening and closing procedures can be set according to different pipeline control requirements to ensure that the opening and closing procedures are satisfied. When the valve conditions are met, the valve can automatically set the time and angle to open and close in two stages, fast and slow. It can also close the valve without electricity, effectively eliminate destructive water hammer, reduce the pressure fluctuation of the pipe network system, and ensure the safety of the equipment. Reliable operation.

• The valve adopts a streamlined design, with a flow resistance coefficient < 0.2, and the appearance is novel and beautiful.
