Pneumatic clamp type soft seal butterfly valve D671X

D671XPneumatic clamp type soft seal butterfly valveAdopting a double eccentric structure, it has a sealing function that becomes tighter as it closes, with good sealing performance. The sealing auxiliary material is paired with stainless steel and nitrile oil resistant rubber. The rubber sealing ring can be located on the valve body or on the butterfly plate, and can be suitable for different characteristics of media for users to choose from. The butterfly plate adopts a frame structure, with high strength, large overcurrent area, and low flow resistance. The overall baking paint can effectively prevent rust and can be used in different media as long as the sealing material of the valve seat is replaced. The D671X pneumatic clamp butterfly valve has bidirectional sealing function, which is not controlled by the flow direction of the medium or the spatial position during installation, and can be installed in any direction. This valve has a unique structure, flexible operation, labor-saving, and convenience.

The D671X pneumatic clamp butterfly valve adopts a clamp center plate structure, mainly composed of a valve body, a valve plate, a valve shaft, a valve seat, and a transmission device. The structure is simple and compact, small and lightweight, and easy to transport, install, and disassemble; 90 ° opening and closing, quick switching, low operating torque, labor-saving and lightweight; Good sealing performance, long service life, and can achieve zero leakage; Its flow characteristics are similar to a straight line, with good regulation performance. The valve is sealed with rubber, and when closed, the sealing performance between the butterfly plate and the valve seat is good, with excellent bidirectional sealing performance and low torque value. The valve maintains 100% zero leakage under working pressure, and the friction between the butterfly plate and the valve seat seal is small. The D671X pneumatic clamp butterfly valve is driven by the valve shaft to rotate the valve plate 90 degrees. The butterfly plate opens and closes flexibly, without jamming or jumping, and has low torque.

Soft sealed center line clamp butterfly valve, double eccentric flange butterfly valve has a compact structure, easy 90 ° rotary switch, reliable sealing, and long service life. D671X pneumatic clamp butterfly valve is used in water plants, power plants, steel mills, papermaking, chemical, textile, food and other water and gas pipelines to regulate flow and intercept media.

The D671X pneumatic clamp butterfly valve adopts a new series of GT type pneumatic actuators, which have double acting and single acting (spring reset), gear transmission, and are safe and reliable; The large-diameter valve adopts a series of AW type pneumatic actuators with fork type transmission, with a reasonable structure and high output torque.

1. Cut off accessories: single electric control solenoid valve, dual electric control solenoid valve, limit switch feedback device

2. Adjustable accessories: electrical locator, pneumatic locator, electrical converter

3. Air source processing accessories: air filtration pressure regulating valve, air source processing triad

4. Adopting an electric pneumatic valve positioner, powered by electrical signals and compressed air, it receives 0-10mA DC or 4-20mA DC current signals from the control system input. The regulator converts the compressed air into a gas source pressure signal input and output, changing the rotation angle of the valve plate (any angle from 0-90 °), and has good control over flow rate and other parameters

5. Adopting electromagnetic directional valve and valve position feedback device, powered by AC220V or DC24V power supply voltage and compressed air, to achieve fast two position cut-off control of fluid medium. The pneumatic actuator adopts a piston type cylinder and a curved arm conversion structure, with a large output torque and a small volume precision

6. The cylinder block adopts a mirror cylinder, oil-free lubrication, low friction coefficient, corrosion resistance, and has super durability and reliability. All transmission bearings adopt boundary self-lubricating bearings without oil lubrication to ensure that the transmission shaft does not wear out
