Pneumatic Plastic Diaphragm Valve is a plastic diaphragm valve driven by a pneumatic actuator, which is widely used to control fluids in chemical media, food, pharmaceutical, and other industries.

Features

Strong corrosion resistance
The valve body and diaphragm of the Pneumatic Plastic Diaphragm Valve are made of UPVC, CPVC, PVDF, and PPH, highly corrosion-resistant materials, which can resist the erosion of various corrosive media such as acid, alkali, and salt solutions.

Easy installation
Pneumatic Plastic Diaphragm Valve provides a variety of connection methods such as flange, thread, and welding connection, and complies with international standards such as GB, ANSI, and JIS. It can be easily connected to different systems, and the installation time only takes 15 minutes, which saves about 40% of the time compared to traditional valve installation.

Low maintenance cost
Due to the simple structural design of the Pneumatic Plastic Diaphragm Valve, metal parts are avoided from contact with fluids, which effectively reduces corrosion and pollution. Compared with traditional metal valves, the maintenance cost of the Pneumatic Plastic Diaphragm Valve is reduced by about 30%.

High sealing performance
The valve adopts high-quality diaphragm materials such as EPDM, FPM, PFA, etc., ensuring a low leakage rate of less than 0.01% under a working pressure of 1.0 MPa.

Precise regulation
The Pneumatic Plastic Diaphragm Valve is equipped with a high-response pneumatic actuator, providing precise flow control and capable of adjustment within a ±2% accuracy range, ensuring high efficiency of industrial processes.

Applications

• Chemical and water treatment: stable control of acid and alkali liquids, chlorides, wastewater, and other media.
• Biopharmaceuticals and food and beverages: used for aseptic process pipelines and pipeline control of beer, beverage, dairy products, and other production lines.
• Electronics and semiconductor industry: suitable for the transportation of ultrapure water, cleaning fluids, chemical reagents, etc.
• Environmental engineering and sewage treatment: control sludge transportation, chemical agent addition, and adjust the airflow of aeration tanks.
