Different processes demand specific valve designs. Below is a comparison of the most commonly used valve types in sanitary processing:
Diaphragm Valve
Fermentation tanks, mixing vessels, fillers, CIP/SIP systems. Isolates process fluid from the environment; smooth internal surface; supports complete drainage.
Ball Valve
Product transfer lines, shut-off applications, diverting flow (3-way). Smooth, crevice-free bore; easy to clean; “fully drained” designs available.
Butterfly Valve
Handling lower-viscosity liquids like milk, beer, juices, water. Compact design; thin valve disc minimises pressure drop; suitable for CIP.
Check Valve
Preventing backflow in pipelines to avoid contamination. Designed for cleanability; often made of polished stainless steel.
Regulating/Control Valve
Precise control of flow, pressure, and temperature for processes like pasteurisation. High-precision internal polishing; meets strict leakage standards (e.g., ASME B16.104 V).
Core Valve Types for Hygienic Applications
At Shield Engineering & Technology Co., Ltd., we understand the critical role valves play in your food and beverage production.
We are committed to providing more than just components; we offer hygienic flow solutions that ensure safety, efficiency, and compliance.
Our expertise covers the supply and integration of high-quality sanitary valves, including diaphragm, ball, and butterfly valves, designed to meet the strictest international standards.
We focus on:
Application-Focused Selection: Helping you choose the optimal valve type and specification for your specific process, whether it’s dairy, beverages, sauces, or brewery applications.
Commitment to Compliance: Supplying valves that adhere to relevant FDA, 3-A, and EHEDG guidelines, with material traceability and supporting documentation.
Technical Support: Offering expert guidance on installation, maintenance, and integration to optimise your process performance and hygiene.
Essential Material & Design Standards
Selecting the right valve involves stringent material and design criteria to ensure safety, durability, and cleanability.
-
Material Selection: The primary material is austenitic stainless steel (AISI 304 or 316/316L) due to its excellent corrosion resistance and inert properties. For seals and diaphragms, food-grade elastomers like EPDM, Silicone, PTFE (Teflon), and FKM (Viton) are used, selected for their compatibility with product and cleaning agents.
-
-
Surface Finish: A smooth, polished internal surface is non-porous, prevents bacterial adhesion, and facilitates cleaning. Finishes are measured by Ra (Roughness average), with Ra ≤ 0.8 μm being standard and Ra ≤ 0.5 μm specified for ultra-hygienic applications.
-
-
Cleanability (CIP/SIP): Valves must be designed for Clean-in-Place (CIP) and Sterilize-in-Place (SIP) processes. This means no dead legs or cavities where product or cleaning fluids can stagnate. Design features like a 15-30° recommended installation angle for diaphragm valves ensure complete drainage.
-
-
Connections: To facilitate fast disassembly for inspection or maintenance, hygienic clamp (Tri-Clamp), SMS, or DIN connections are standard, replacing traditional flanges in product contact areas.

Resilient Seated Butterfly Valve
The resilient seated butterfly valve stands out for its simplicity, reliability, and cost-effectiveness. It is a quarter-turn valve used to start, stop, and regulate the flow of liquids and gases in a piping system.¥ 0.00Buy now
-
Small Size Ball Valve
A threaded ball valve is a crucial component in industrial fluid control systems, known for its robust design and reliable shut-off capability. As the name suggests, this valve features threaded ends (often NPT threaded or BSP threaded), allowing for straightforward installation into piping systems without the need for welding. Its versatility makes it a preferred choice across sectors like water treatment, oil and gas, and chemical processing.¥ 0.00Buy now
