Product Introduction：
D671X-16Q Pneumatic Wafer type butterfly valve, which is composed of piston type double acting or single acting (spring return) pneumatic actuator and butterfly valve, is a rotary high-performance regulating or shut-off valve. It is equipped with electric pneumatic valve positioner or solenoid valve, air filter pressure reducer and limit switch (valve position annunciator), which can realize the proportional regulation and two position cut-off control of fluid medium in process pipeline, so as to achieve the flow, pressure, temperature Automatic control of liquid level parameters, etc. It is widely used in gas, turbid liquid, concentrated slurry or ash powder, suspended particles and other media.
1. The pneumatic butterfly valve has a small operating torque, which is one of all valves. It can be opened and closed quickly. Driven by compressed air, it can rotate the valve plate by 0 ~ 90 ° with the torque output by angular stroke through the mechanical transmission valve rod of piston, rack and gear. It has the advantages of simple structure, small volume, light weight, small flow resistance, large flow coefficient and good sealing performance. Large adjustment range. The execution unit of the instrument is the control unit in the instrument system;
2. The D671X-10Q Pneumatic wafer type butterfly valve positioner is adopted, which takes the electrical signal and compressed air as the power, receives the 0-10mA DC or 4-20mA DC current signal input by the control system, converts the compressed air into the air source pressure signal input and output by the regulator, changes the rotation angle of the valve plate (any angle of 0-90°), and has a good ability to adjust and control the flow and other parameters.
3. The electromagnetic directional valve and valve position annunciator are adopted, and the AC220V or DC24V power supply voltage and compressed air are used as power to realize the fast two position cut-off control of fluid medium.
4. The pneumatic actuator adopts piston cylinder and curved arm conversion structure, with large output torque and small volume. It adopts fully sealed waterproof design and high protection grade. The cylinder block adopts mirror cylinder, oil-free lubrication, small friction coefficient, corrosion resistance, super durability and reliability. All transmission bearings adopt boundary self-lubricating bearings without oil lubrication to ensure that the transmission shaft is not worn.
