3A Manual Diaphragm Valves Clamp - Stainless Steel Sanitary Valves for High-Purity Applications
The 3A certified Eagle manual diaphragm valve, with its tri-clamp connections, offers the highest level of sterility assurance for high-purity process piping within the pharmaceutical, biotech, and food applications. Eagle, the pioneering name in sanitary diaphragm valves, offers proven manual diaphragm valves that provide clean, dry, contamination free operation in highly critical aseptic processes.
Price Range: $770 - $4,823 | Size Range: 1/2" to 4" | Connection: Tri-Clamp | Certification: 3-A, FDA cGMP Compliant
Why Select Eagle 3A Manual Diaphragm Valves with Clamp Connections
Easy Installation & Service
Tri-clamp fittings enable quick connection and disconnection without the use of special tools, reducing downtime when performing maintenance or making system modifications.Ideal for applications with frequent cleanings or change-outs.
Absolute Sterility Assurance
The diaphragm fully separates process media from the valve internals so there is no risk of contamination. This stainless steel diaphragm valve configuration is critical for aseptic processing in biopharm applications.
3-A Certified Sanitary Design
All the 3-A valves from are fully compliant with the most rigorous 3-A sanitary standards for food, dairy and pharmaceutical use. The clamp connection design creates a crevice-free seal which eliminates bacterial harborage.

Key Applications for Clamp-Style Diaphragm Valves
Pharmaceutical & Biotech Processing
Aseptic filling lines, bioreactor sampling, and buffer preparation systems: Our 1/2 to 4" size clamp-style manual diaphragm valve in the asq series provides sterile isolation in these applications with excellent access for maintenance. The tri-clamp fittings also allow for quick changeover in a multi-product plant.
"Our plant is designed with Eagle clamp diaphragm valves throughout our production in the aseptic environment. The quick disconnect design enables cleaning validation to be completed more efficiently between product runs." - Manager of Quality Biopharmaceuticals
Food & Beverage Manufacturing
These sanitary diaphragm valves are tested and proven in dew production, brewing and beverage applications that must meet 3-A. The clamp fittings make disassembling things for CIP (clean-in-place) validation, a lot easier.
"We standardized on Eagle clamp valves for our dairy processing expansion. With the 3A certification, and the access for maintenance was so good that it leaped the validation time by 30%." - Food Plant Engineer
CIP/SIP Systeme und Utilities
In cleaning and sterilizing systems, the clamp configuration permits fast changing of parts and maintenance work. The stainless steel construction of the diaphragm valve is designed for multiple sterilization cycles (Max 135ºC with max 60 minutes/sterilization cycle) and continuous operation.
“We never had the possibility of changing diaphragms quickly without pulling the entire valve body out of the line until now, and this has made a huge difference in our maintenance downtime.” – Facility Maintenance Supervisor
Material Specifications & Design Advantages
Body Material: 316L Stainless Steel (Electropolished) | Diaphragm: EPDM (Standard) or VMQ (Optional) | Connection: Tri-Clamp (Sanitary Clamp) | Operation: Manual Handwheel
Zero Dead Leg Configuration
Straight-through flow path minimizes product hold-up and supports effective cleaning validation for pharmaceutical applications.
Diaphragm Isolation Technology
Process media never contacts valve internals, eliminating contamination risks from stem seals or packing glands.
Quick-Change Diaphragm Design
Diaphragm replacement can be performed in minutes without special tools or removing the valve from the pipeline.
Sanitary Surface Finish
All wetted surfaces are electropolished to Ra ≤ 0.8μm, exceeding sanitary requirements for high-purity applications.
Certifications & Quality Assurance
Every Eagle 3A manual diaphragm valve with clamp connections is manufactured under strict quality controls and includes comprehensive documentation for regulatory compliance.
Compliance Standards: 3-A Sanitary Standard | FDA cGMP 21 CFR Part 211 | ASME BPE Standards | EHEDG Guidelines | ISO 9001:2015 Quality Management
Material Traceability
Full material certificates with heat number traceability for all 316L stainless steel components, supporting pharmaceutical validation requirements.
Pressure Testing
Each valve undergoes hydrostatic testing at 15 Bar (1.5x working pressure) with zero leakage requirements.
Surface Finish Documentation
Surface roughness certification provided for all product contact surfaces, ensuring compliance with sanitary standards.
Cleanability Validation
Design validated for effective cleaning with documented CIP/SIP compatibility for aseptic processing applications.
