1. What are sanitary valves?

Sanitary Valves (Sanitary Valves) are specialized valves designed specifically for industries with high cleanliness and aseptic requirements such as food, beverages, pharmaceuticals, bioengineering, and cosmetics. The core features are anti-pollution, easy cleaning, and no residue.
II. Core Design Features:
• Pure material
The main body is made of 316L / 304 stainless steel, which is corrosion-resistant, non-toxic and does not react with the medium.
• The inner wall is extremely smooth
The inner surface is mirror-polished with Ra ≤ 0.8μm (even Ra ≤ 0.4μm), preventing bacteria from adhering.
• No blind spots, complete emptying
No grooves, no threads, no dead zones. The fluid can be completely emptied, preventing the growth of bacteria.
• CIP / SIP Online Cleaning and Sterilization
Supports in-situ cleaning (CIP) and in-situ steam sterilization (SIP), allowing for thorough cleaning without the need to remove valves.
• Hygienic sealing
Made of FDA/3A certified materials: EPDM, silicone, PTFE, etc., non-toxic, high-temperature resistant, no leaching.
• Quick-install connection
Tri-Clamp couplings, welding, threads. Easy to install and remove, and highly maintainable.
• Compliance Certification
Complies with FDA, 3-A, EHEDG, GMP, ISO and other hygiene standards.
III. Common Types and Uses
• Hygienic ball valve
Low flow resistance, quick opening and closing, full diameter, no dead space; suitable for milk, beverages, syrups, pure water.
• Hygienic diaphragm valve
No contact between the medium and the valve stem, zero pollution, extremely strong sealing; preferred for pharmaceuticals, injection water, and aseptic systems.
• Hygienic butterfly valve
Simple structure, large diameter, low pressure, low cost; suitable for beer, beverages, large flow pipelines.
• Hygienic check valve (one-way valve)
Prevents backflow, no dead space; prevents backflow of the medium and contamination of the system.
Four. Core selling points of hygienic valves (must be viewed for sales/selection)

1. Hygiene and Safety: Zero Pollution, No Residues
• All stainless steel + mirror polishing + no dead corners, no dirt accumulation, no bacterial growth.
The sealing material has received FDA/3A certification. It is non-toxic, odorless, non-adsorptive and non-migratory.
Completely meets the GMP, FDA, 3A, and EHEDG compliance requirements.
2. Easy to Clean: CIP/SIP is convenient and efficient
• Supports online cleaning and sterilization, without the need to remove the valve, with short downtime and low labor costs.
Full emptying design ensures no residue of cleaning solution and thorough sterilization.
3. Long lifespan, low maintenance
316L stainless steel is resistant to corrosion, acid and alkali, and high temperature.
The structure is simple and it features a quick-installation design. Assembly, disassembly and cleaning can be completed within just 10 minutes.
• The sealing is reliable, with zero leakage, long service life and low failure rate.
4. Excellent fluid performance
The flow resistance is extremely low, the flow rate is high, and the pressure loss is small.
Quick opening and closing, stable control, suitable for automation.
5. Compliance and Quality Assurance
• Compliant with food/pharmaceutical grade regulations, easy to obtain approval, stable quality, and high brand trust.
V. Applicable Industries
• Food and beverages: Milk, yogurt, beer, juice, soy sauce, cooking oil
• Pharmaceuticals/Biology: Injection water, purified water, sterile medicinal solutions, biological fermentation
• Cosmetics: Lotion, cream, perfume, hair care products
• Fine chemicals/semiconductor: High-purity fluids, ultra-pure water
VI. Summary in One Sentence
Sanitary valves = Cleanliness and Safety + Easy Cleaning + Long Life + Compliance Certification
They are the standard valves for high hygiene requirements production lines in industries such as food, pharmaceuticals, beverages, and cosmetics.
