The pneumatic sanitary clamp butterfly valve is composed of pneumatic actuator and high-quality sanitary butterfly valve body. The sanitary grade pneumatic butterfly valve adopts standard electronic polishing, with smooth surface to ensure cleanness, no medium accumulation area and no potential pollution. The valve can be disassembled and disassembled quickly and easily to open and maintain the valve, and the shutdown time of the process can be shortened.
1. Simple, small volume, light weight, small flow resistance, large flow coefficient and good sealing performance. The adjustment range is large. It is the executive unit of instrument in automatic control system.
2. The pneumatic actuator adopts piston type cylinder and crank arm conversion structure, with large output torque, small volume, fully sealed waterproof design and high protection level. The cylinder block adopts mirror cylinder, no oil lubrication, small friction coefficient, corrosion resistance, super durability and reliability. All drive bearings adopt boundary self-lubricating bearing without oil lubrication to ensure that the transmission shaft is not damaged.
