Overview of Pneumatic Clamp Control Butterfly Valve Products

1. Pneumatic butterfly valves have a small operating torque and are the smallest among all valve types. They open and close quickly, powered by compressed air. The valve stem is mechanically transmitted through a piston rack and gear, and the valve plate can be rotated 0-90 ° with torque output by angular stroke to quickly complete the opening and closing action. The structure is simple, the volume is small, the weight is light, the flow resistance is small, the flow coefficient is large, and the sealing performance is good. The adjustment range is large. It is the execution unit of instruments in the automation control system;

2. Using 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.

3. 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.

4. The pneumatic actuator adopts a piston type cylinder and a curved arm conversion structure, with large output torque, small volume, and a fully sealed waterproof design with high protection level. 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 is not worn.
