Key Design Features
Back seal multiple leakage-proof design
Provides a secondary sealing layer that significantly reduces the risk of external leakage at the stem.
Adjustable packing without disassembly
Field maintenance of stem sealing can be performed while the valve remains in line, reducing downtime.
Seat resilient seal design
Ensures consistent seating load and bi-directional sealing integrity across the rated pressure range.
Stem prevent ejection & scratch design
The stem is mechanically retained against blowout, protecting both personnel and system integrity under pressure.
Full bore design
The 3 way tri clamp valve maintains unobstructed flow through the active port, minimizing pressure drop and supporting CIP/SIP cleaning efficiency.
ISO5211 mounting pad
Direct actuator mounting compatibility across the full size range for automation upgrade without additional adapters.
Applications
This sanitary three way valve is designed for process environments where hygiene, cleanability, and reliable flow diversion are non-negotiable:
- Food & Beverage - tank outlet switching, product routing between process lines, CIP return circuits
- Dairy & Brewing - divert or combine product flows without cross-contamination risk
- Pharmaceutical & Biotech - SIP-compatible construction meets the demands of sterile process systems
- Cosmetics & Personal Care - smooth internal surfaces prevent product trapping and bacterial buildup
- Chemical Processing - CF8M body and F316 internals handle aggressive media and chloride-containing fluids

Frequently Asked Questions
Q: What is the difference between CF8 and CF8M body material?
A: CF8 is the cast equivalent of SS304, suited to most water, steam, and general process media. CF8M is the cast equivalent of SS316, with added molybdenum for significantly better resistance to chlorides and acidic fluids. For dairy, pharmaceutical, or chemical applications, CF8M is the recommended choice.
Q: What is the maximum operating pressure and temperature range?
A: This valve is rated to PN16 and operates between -40°C and 180°C, making it suitable for both cryogenic-adjacent and high-temperature steam applications within the rated range.
Q: How do I select between F304 and F316 for the ball and stem?
A: F304 covers the majority of food, beverage, and general industrial applications. F316 should be specified when the process media contains chlorides, salt solutions, or acidic compounds - such as in certain pharmaceutical, chemical, or coastal installation environments.
Q: Can this valve handle CIP and SIP cleaning cycles?
A: Yes. The full bore design and PTFE seat/gasket construction support in-line CIP cleaning without disassembly. The adjustable packing feature also allows stem seal maintenance without removing the valve from the pipeline, minimizing process disruption during maintenance windows.
Q: What is the minimum order quantity, and do you offer samples?
A: We support flexible order quantities from small development batches to full production volumes. Free samples are available for qualification - contact us at info@cnleadtek.com with your size and material requirement to arrange.
