Stainless Steel Sanitary Automatic Membrane Control Valve
Pneumatic sanitary membrane control valve is suitable for various pressure, temperature, flow and other physical quantity adjustment, such as food, pharmaceutical, cosmetics, clean steam, alcohol, beverage, biochemical industrial process control occasions. It has the advantages of compact structure, convenient assembly and disassembly, and high adjustment accuracy, especially in the small pressure drop loss, large flow, wide adjustable range, and high flow accuracy, which fully meets the IEC534-1-1978 standard. The valve leakage volume complies with the ANSIB16.104 standard. The regulating valve is equipped with different multi-spring actuators and has a large output force.
Features and benefits:
The angular design ensures self-draining of the valve, standard electronic polishing, and smooth surfaces ensure cleanliness, no medium accumulation area, and no potential pollution. Quick disassembly of valve body and bonnet makes valve opening and maintenance quick and easy, and shortens process downtime.
