Product Description

Hygienic Pneumatic External Thread Butterfly Valve

Sanitary pneumatic external butterfly valve has good flow regulation and shut-off sealing characteristics; hygienic pneumatic external butterfly valve adopts standard electronic polishing, smooth surface ensures clean, no media accumulation area, no potential pollution; sanitary external pneumatic thread The butterfly valve quick disassembly valve enables the valve to open and service quickly and easily, butterfly valve, Wafer Type Butterfly Valve, Weld Type Butterfly Valve,Flanged Butterfly Valve,

Lug Type Butterfly Valve,
reducing process downtime.



First, the characteristics of sanitary external butterfly valve

1, the design is novel, reasonable, unique structure, light weight, rapid opening and closing.

2, small torque, easy operation, effort and dexterity.

3, can be installed anywhere, easy maintenance.

4, sealing material, anti-aging, corrosion resistance, long service life and other characteristics.

Second, sanitary grade pneumatic butterfly valve working principle

Hygienic pneumatic butterfly valves are used in dairy products, food, pharmaceuticals, beer, cosmetics and other industrial fields. All parts in contact with the media are mirror-polished. The sealing ring Ф25-Ф108 can be used in two ranges: EPDM, silicone (SI), Ф57 and below is EPDM; the opening and closing parts reciprocate about 90° to open, close and adjust the fluid. A Stainless Steel Butterfly Valve.

The hygienic pneumatic butterfly valve not only has the advantages of simple structure, small size, light weight, material consumption, small installation size, but also small driving torque, simple and rapid operation, and can also have good flow regulation and close sealing properties at the same time. When fully opened, the hygienic, externally actuated butterfly valve has a low flow resistance and can perform sensitive flow control when it is opened between approximately ° and 70°, so that in the field of large diameter adjustment, the movement of the valve plate With wiping properties, it can be used for media with suspended solid particles, and can also be used for powdered and granular media depending on the strength of the seal.

Third, hygienic external thread butterfly valve use

The hygienic pneumatically actuated butterfly valve adopts standard electronic polishing. The smooth surface ensures cleanness, no media accumulation area and no potential pollution. Quickly disassemble the valve, make the valve open and repair quickly and easily, and shorten the process downtime. With a compact structure, easy assembly and disassembly. Extensive sanitary pneumatic butterfly valves are used in process control applications such as food, pharmaceuticals, cosmetics, clean steam, alcohol, beverages, and biochemical industries.

Fourth, sanitary pneumatic butterfly valve sealing performance:

The hygienic pneumatic external thread butterfly valve belongs to the midline stainless steel soft seal butterfly valve. Its sealing principle is that when the valve plate is processed, its sealing surface has an appropriate surface roughness value, and the synthetic rubber valve seat forms a suitable rough surface of the sealing surface during the compression molding. value. When the stainless steel butterfly valve is closed, the hygienic pneumatic external butterfly valve rotates through the valve plate, and the outer circular sealing surface of the valve plate presses the synthetic rubber valve seat, so that the synthetic rubber valve seat generates elastic deformation and the elastic force acts as a sealing ratio to ensure the sealing of the valve.
