D671X pneumatic sandwich soft seal butterfly valve

D671X pneumatic clamp soft seal butterfly valve adopts double eccentric structure, with the sealing function of tighter and tighter, and the sealing performance is reliable. The sealing auxiliary material is made of stainless steel and nitrile oil resistant rubber, which has a long service life. Rubber sealing ring can be located on the valve body, can also be located on the butterfly plate, can be applicable to different characteristics of the media, for the user to choose. The butterfly plate adopts the frame structure, high strength, large flow area and small flow resistance. The whole paint, can effectively prevent rust and as long as the replacement of the sealing seat sealing material, it can be used in different media. D671X pneumatic clamp butterfly valve has a two-way sealing function, the installation is not controlled by the flow of the medium, nor affected by the spatial position, can be installed in any direction. The valve has unique structure, flexible operation, labor-saving and convenient.
Pneumatic clamp type soft seal butterfly valve structure characteristics
D671X pneumatic clamping butterfly valve adopts splint type structure, mainly composed of valve body, valve plate, valve shaft, valve seat and transmission device, simple and compact structure, compact and lightweight, convenient transportation, installation and disassembly; 90 opening and closing, fast switching, small operating torque, labor-saving and lightweight; Good sealing performance, long service life, can achieve zero leakage; Its flow characteristics are similar to a straight line, and the adjustment performance is good. The valve is rubber sealed, the sealing performance of the butterfly plate and the seat is good when it is closed, the two-way sealing performance is excellent, the torque value is small, the valve is maintained under the working pressure, and the friction between the butterfly plate and the seat seal is small. D671X pneumatic clamping butterfly valve is driven by the valve shaft valve plate, valve plate to do 90° rotation. Butterfly plate open and close flexible, no jammed, jumping phenomenon, small torque.
Pneumatic clamp type soft seal butterfly valve product use
Soft seal middle line clamp butterfly valve, double eccentric flanged butterfly valve compact structure, 90° rotary switch easy, reliable seal, long service life, D671X pneumatic clamp butterfly valve is widely used in water plants, power plants, steel mills, paper making, chemical, textile, food and other water supply and drainage, gas pipeline for regulating flow and intercepting media.
Pneumatic clamping soft seal butterfly valve actuator
D671X pneumatic clamp butterfly valve adopts a new series GT type pneumatic actuator, with double acting and single acting (spring return), gear transmission, safe and reliable; Large diameter valve adopts series AW type pneumatic actuator fork type transmission, reasonable structure, large output torque.
1, cut off type accessories: single electronically controlled solenoid valve, double electronically controlled solenoid valve, limit switch back actuator
2, regulating accessories: electrical positioner, pneumatic positioner, electrical converter
3, air source processing accessories: air filter pressure regulator, air source processing triplets
4. The use of electric-gas valve positioner, electrical signal and compressed air as the power, accept the control system input 0-10mA DC or 4-20mA DC current signal, the regulator will be compressed air, into the air source pressure signal input and output, change the rotation Angle of the valve plate (0-90° any Angle), with better regulation control flow and other parameters
5, the use of electromagnetic reversing valve, valve position return device, AC220V or DC24V power supply voltage and compressed air as the power, to achieve the rapid two-position cut off control of fluid media. Pneumatic actuator adopts piston type cylinder and bend arm conversion structure, the output torque is large, the volume is small, and the protection level is high with full seal waterproof design
6, the cylinder body adopts mirror cylinder, oil-free lubrication, small friction coefficient, corrosion resistance, durability and reliability. All transmission bearings are using boundary self-lubricating bearings oil-free lubrication, to ensure that the drive shaft does not wear and tear
