SCH8O/DIN Pneumatic UPVC Double Driven Diaphragm Valve

The pneumatic UPVC double driven diaphragm valve is made from UPVC material, offering corrosion resistance and lightweight characteristics. With a double driven design operated pneumatically, the valve is highly flexible and reliable. It operates based on pneumatic force and the diaphragm's lifting motion. By controlling the air source to change the pressure in the air chamber, the diaphragm moves up and down, enabling valve opening and closing. It is commonly used in applications requiring corrosion resistance and fluid control, such as in chemical, pharmaceutical, and food processing industries. The valve features a simple structure, low maintenance costs, and extended maintenance intervals. Its precise flow control makes it suitable for various fluid media.

Parameter Application Technical Standards

  • The feature of the pneumatic UPVC dual-route diaphragm valve is that the diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the valve stem, valve disc, and other parts located above the diaphragm are not corroded by the medium, and the packing seal structure is omitted, and No medium leakage occurs. The inner cavity partition is a diaphragm made of rubber or plastic with a soft seal, which has good sealing performance.

SCH8O/DIN Pneumatic UPVC Double Driven Diaphragm Valve Industry knowledge

How to choose pneumatic UPVC diaphragm valves in the chemical and environmental protection industries?

Pneumatic UPVC dual-drive diaphragm valves are widely used in chemical, environmental protection and many high-demand industries due to their excellent corrosion resistance, reliable sealing and lightweight characteristics. The following are the selection points and typical scenario analysis of different industries:

1. Safe Drinking Water & Drinking Water
Selection points: The valve body must meet food-grade hygiene standards (such as FDA, NSF certification) to ensure that there is no heavy metal precipitation; the dual-drive design can prevent medium backflow contamination.
Application scenarios: water plant disinfection system, pure water delivery pipeline, community water supply network.

2. Metallurgy industry (Metallurgy)
Selection points: UPVC needs to withstand acidic/alkaline smelting wastewater (such as sulfuric acid, hydrofluoric acid medium); pneumatic drive is suitable for remote control of high-temperature workshop processes.
Application scenarios: pickling line waste liquid treatment, electroplating wastewater discharge, smelting cooling water circulation system.

3. Photovoltaic & Electronic Semiconductor
Selection points: Ultra-high purity requirements, valves must not fall off particles; UPVC's hydrofluoric acid resistance is suitable for wafer cleaning processes.
Application scenarios: photovoltaic silicon acid etching waste liquid control, semiconductor ultrapure water transportation, PCB board etching line.

4. Nuclear Power
Selection points: Need to pass radiation-resistant material testing; dual-drive structure ensures zero leakage of nuclear waste liquid, and pneumatic actuators require explosion-proof certification.
Application scenarios: low-level radioactive wastewater treatment, coolant pipelines, nuclear fuel reprocessing systems.

5. Medicine
Selection points: The inner wall of the valve body is smooth and has no dead corners to avoid microbial growth; UPVC is compatible with ethanol, sodium chloride and other agents.
Application scenarios: pharmaceutical purified water system, aseptic filling line, CIP (cleaning in place) pipeline.

6. Industrial Water Treatment & Wastewater
Selection points: For wastewater containing chlorine, high salt or organic solvents, it is necessary to select a thickened UPVC valve body; pneumatic control can be linked to PLC to achieve automatic dosing.
Application scenarios: desulfurization wastewater in power plants, neutralization tanks in petrochemical plants, and dye wastewater discharge in the printing and dyeing industry.

General selection suggestions
Corrosive media: Confirm the chemical resistance of UPVC (such as hydrochloric acid, sodium hypochlorite, etc.);
Particle content: It is recommended to add a valve cavity flushing function for high solid content fluids;
Automation requirements: Prioritize the use of intelligent positioners to adapt to DCS/SCADA system integration.
