Pneumatic Fluorine-Lined Bellows Control Valve
The pneumatic fluorine-lined bellows control valve consists of two main components: a pneumatic diaphragm actuator and a straight-through single-seat fluorine-lined bellows control valve body. All parts of the valve body that come into contact with corrosive media are made of corrosion-resistant, anti-aging polyvinylidene fluoride (PVDF) using high-pressure fluoroplastic coating technology, and feature a PTFE bellows seal.

Product Details

Pneumatic fluorine-lined bellows control valves regulate the flow of highly corrosive media such as acids and alkalis, as well as toxic volatile gases and liquids. Consequently, these valves are widely applicable in chemical, metallurgical, pharmaceutical, and other industries. Key features include:

(1) Excellent corrosion resistance: The valve body cavity, plug, and seat are lined with 3mm-thick polyvinylidene fluoride (PVDF), enabling resistance to highly corrosive fluids.

(2) Superior sealing performance: Utilizes dual sealing with PTFE bellows and packing.

(3) Minimal leakage: Soft sealing of the plug and seat ensures leakage far below National Class IV standards.

(4) High Control Accuracy: Utilizes compact pneumatic and electric actuators, featuring small size and light weight.
