Sanitary Tri-Clamp Diaphragm Valve
KINGMAN supplies sanitary clamp manual diaphragm valves. Featuring tri-clamp structure for quick assembly and disassembly without welding, it enables easy inspection and cleaning. The stainless steel valve body has smooth flow channel. The handwheel controls opening and closing, and the diaphragm isolates medium from drive mechanism to avoid cross-contamination. Suitable for clean pipelines in food, beverage and daily chemical industries and compatible with in-place cleaning & sterilization. Maintenance and disassembly require no pipe cutting, perfect for production lines requiring frequent breakdown and cleaning. EPDM / TFM diaphragms are optional to satisfy temperature resistance and anti-corrosion demands of different media.

Diaphragm
Different from the traditional diaphragm valve body, the aseptic diaphragm valve body has a sealing protrusion that tightly snaps on the inner diameter, which can reduce the annular gap between the diaphragm and the valve body. This feature of the diaphragm valve makes it particularly suitable for aseptic processe.
Diaphragm Material
Diaphragms are available in EPDM rubber and TFM rubber, with single and double diaphragms optional. The dual diaphragm design allows the two diaphragms to operate independently,which reduces tension caused by different thermal properties. Each application has different operating conditions and therefore different requirements for the diaphragm. To select the diaphragm that is best for you, consider the following factors: operating pressure, application temperature, process fluid. EPDM can be suitable for most application conditions, and some high-temperature conditions require the use of TFM material diaphragms.

Working Principle
Sanitary Clamp Diaphragm Valve: Rotate the handwheel to drive the spindle up and down, transmitting axial force to act on the flexible diaphragm. When the spindle moves down, it pushes the diaphragm and presses it firmly onto the weir inside the valve body, forming a reliable face seal to fully seal the flow passage and stop medium flow. When the spindle rises, the diaphragm rebounds and lifts off the weir, fully opening the channel for stable medium flow. The diaphragm acts as a complete physical barrier that isolates process media from all of the valve’s upper mechanical parts, including spindle, threads and transmission assembly. This separation prevents cross-contamination and protects process fluid from contact with metal moving components. Tri-clamp ends allow quick assembly and disassembly for thorough CIP/SIP cleaning, internal inspection, diaphragm replacement and routine maintenance without cutting or rewelding the pipeline.
