Tri-Clamp Diaphragm Valve

Maintaining a clean fluid path is critical in industries where even minor contamination can affect production quality. The DINGYUE Tri-Clamp diaphragm valve features a diaphragm-based isolation structure that separates the operating mechanism from the process media, reducing the risk of leakage and product contamination. With a sanitary clamp connection design, the valve supports convenient installation, cleaning, and maintenance in sterile piping systems. Manufactured for applications including pharmaceutical processing, food and beverage production, and data center liquid cooling systems, it provides stable flow regulation and reliable media isolation under strict hygiene requirements.

Technical Specifications

A tri clamp diaphragm valve is only as good as its materials. We use traceable, certified raw materials to ensure maximum corrosion resistance and longevity.

How a tri clamp Diaphragm Valve Works

A tri clamp diaphragm valve is a special type of valve that uses a flexible rubber/plastic piece (called a diaphragm) to separate the fluid path from the inside of the valve top. This design keeps everything clean and safe.

Here is how it works step-by-step:

To Open : When you turn the handwheel, it pulls the stem and compressor upward. The flexible diaphragm moves up with them, leaving the valve seat. Fluid (like water, gas, or chemicals) can now flow smoothly through the valve with almost no resistance or pressure loss.

To Close : When you turn the handwheel the opposite way, it pushes the stem and compressor down. This presses the diaphragm tightly against the valve seat, creating a perfect seal. It completely stops the flow, ensuring 100% leak-free performance

To Adjust Flow : You can also leave the handwheel in a middle position. This allows you to control and adjust how much fluid passes through, which is very useful for managing flow rates.

Key Benefits

Total Separation: The diaphragm completely separates the fluid from the valve's moving parts (like the stem). This means the fluid won't rust or damage the valve, and the valve won't contaminate your fluid.

Clean & Hygienic : The inside of the valve body is super smooth with no dead corners where dirt can hide. It is very easy to clean and sanitize, making it perfect for the food, beverage, and pharmaceutical (medicine) industries.

Excellent Sealing: The flexible diaphragm creates a tight seal every time. Even if your fluid contains tiny solid particles, fibers, or is very thick (viscous), the valve can still shut off completely without getting stuck.

Anti-Corrosion: The valve body and the diaphragm can be made of different materials to match your needs, allowing it to handle various harsh or corrosive liquids safely.

FAQ

Q1: What is the maximum temperature rating for your tri-clamp diaphragm valves?

A: It depends on the diaphragm material. Standard EPDM handles up to 130°C, while our premium PTFE/TFM combined diaphragms can withstand continuous steam up to 150°C.

Q2: Can I get full material traceability for pharmaceutical audits?

A: Absolutely. Every shipment comes with EN 10204 3.1 Material Certificates, FDA compliance letters, and surface roughness inspection reports.
