Pneumatic Clamp Diaphragm Valves

DIYE VALVE pneumatic clamp diaphragm valves are high-performance automatic valves independently developed by our factory, specifically designed for aseptic, high-purity fluid control. As a professional manufacturer, we maintain strict quality control throughout the entire process. Made in China, these valves combine superior materials and advanced structure, solving the contamination and cleaning problems of traditional valves, making them core components of aseptic production lines.

Core Product Features

1. Superior Materials and Structural Design

The pneumatic clamp diaphragm valves use industry-recognized SUS316L stainless steel for the valve body, which is corrosion-resistant, high-temperature resistant, and non-toxic. The inner surface is electropolished to prevent microbial adhesion and meets hygiene standards. The diaphragm isolation design (no packing gland) completely isolates the fluid chamber from the actuator, eliminating contamination and ensuring fluid purity.

Equipped with sanitary connections such as clamps, SMS, and DIN, installation and disassembly are convenient, compatible with various sanitary pipelines, and improving maintenance and cleaning efficiency.

2. Stable Working Principle

The pneumatic clamp diaphragm valves are driven by clean compressed air. The actuator moves the diaphragm up and down to achieve on/off control: when the diaphragm is pressed against the valve seat, it closes (zero leakage); when it is raised, it opens the full-bore flow path. Single-acting (automatic reset upon air shortage) and double-acting actuators are available to suit safety and frequent switching scenarios, respectively.

3.Superior Hygiene Performance

The seamless flow channel design prevents material residue and microbial growth; compatible with CIP/SIP processes, allowing for online cleaning and sterilization without disassembly, saving costs and ensuring sterility.

Diaphragm Options:

1. EPDM (Ethylene Propylene Diene Monomer): -10~120℃, flexible and cost-effective, suitable for the food industry and CIP/SIP cleaning scenarios.

2. PTFE Composite Diaphragm: Resistant to strong acids and alkalis, wide temperature range, suitable for corrosive fluid scenarios.

3. Silicone Diaphragm: Non-toxic and odorless, heat-resistant, suitable for the dairy and pharmaceutical industries.

4. FFKM (Fluoropolymer KM): High-temperature and corrosion-resistant, suitable for high-end biopharmaceutical processes.

Pneumatic and Automation Characteristics:

1.High-Performance Actuators

Actuators are available in aluminum alloy/stainless steel materials, single-acting (spring return) and double-acting types, with fast and stable operation (0.5~1s cycle), adaptable to different operating conditions.

2.Strong Control Compatibility

Standard configuration includes solenoid valves and limit switches; optional intelligent positioners and bus modules are available. Integration with PLC/DCS systems is possible, supporting remote control and centralized monitoring to enhance automation levels.

3.Reliable Explosion-Proof Safety

Pneumatically driven and inherently safe, with no electrical sparks, suitable for clean areas and flammable/explosive hazardous locations, ensuring production safety.

Quality Assurance and Customization Capabilities:

1.Strict Quality Control

As a responsible supplier, every pneumatic clamp diaphragm valve undergoes 100% pressure and cleanliness testing before leaving the factory, accompanied by material certificates and test reports, guaranteeing quality.

2.Professional Customization Services

Our factory offers comprehensive customization services, covering special materials, non-standard diameters, and custom connections. Our professional team can tailor solutions to customer needs.

Application Areas

These pneumatic clamp diaphragm valves are widely used in the food, pharmaceutical, and bioengineering industries. As core control components, they are suitable for fluid control processes such as raw material conveying and product processing, ensuring product safety.
