Overview of Pneumatic Diaphragm Sanitary Grade Control Valve:
Pneumatic sanitary grade control valves are suitable for regulating various physical quantities such as pressure, temperature and flow rate, such as in food, pharmaceutical, cosmetic, clean steam, wine, beverage and biochemical industrial process control applications. It features a compact structure, easy assembly and disassembly, and high regulation accuracy. Especially, it has the advantages of small pressure drop loss, large flow rate, wide adjustable range and high flow accuracy, fully complying with the IEC534-1-1978 standard. The leakage of the valve complies with the ANSIB16.104 standard. The control valve is equipped with different multi-spring actuators, providing a large output force. The angular design ensures self-discharge of the valve. The standard electronic polishing makes the smooth surface clean and free of medium accumulation areas, thus avoiding potential pollution. Quick disassembly and assembly of the valve body and valve cap make valve opening and maintenance quick and easy, reducing process downtime.
