Pneumatic Antibiotic Shut-off Valve

Antibiotic globe valves are operated separately from the original three valves, and now they are converted into three-in-one operation, which greatly changes the original appearance, saves trouble and money, breaks the original shut-off valve with poor sealing performance, and the temperature resistance of the diaphragm cannot meet the requirements. Many pharmaceutical factories rely on high-priced imported diaphragms to maintain their operations. The new anti-valve consists of a throttling valve, a stop valve, and a diaphragm valve in one to replace the original antibiotic valve.

Antibiotic globe valves are mainly used in biological fermentation, pharmaceutical and beer fermentation, amino acid fermentation, biological pesticide fermentation, biological fertilizer fermentation, various antibiotic fermentation, biological, biochemical, chemical pharmaceutical materials, water, steam, cold control and other fields. Drain holes can be opened according to customer needs, high temperature resistance and long service life, no dead angle to achieve zero leakage level.

The piston actuator has relatively high strength and can withstand greater air source pressure.
The stroke of the piston actuator is large, and the stroke of the cylinder can be designed according to the stroke of the valve.

Processing process

The inner cavity of the antibiotics intercept valve is required to be polished, because the surface is not easy to accumulate, and the deposition of dirt will cause stainless steel to rust and even cause corrosion. Hygiene conditions are important for many industries, such as food processing, catering, brewing and chemical industry.

The sealing cushion of antibiotics can be replaced, it is more convenient to disassemble, and the maintenance cost is low. It has strong sterilization and poisoning function to prevent product staining. Sealing pads, sealing rings of the middle road of the valve body, and the filling of the valve stem filler are made of polytetrafluoroethylene material. Long life, corrosion resistance, and ensure no internal and external leakage. The sealing pad is made of high-temperature polytetrafluoroethylene composite material. The streamlined runner makes the pressure loss.
