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.

Core Valve Types for Hygienic Applications

Different processes demand specific valve designs. Below are 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; 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).

Material & Design Standards

• Material Selection: Austenitic stainless steel (AISI 304/316L) + food‑grade elastomers (EPDM, Silicone, PTFE, FKM)

• Surface Finish: Ra ≤ 0.8 μm (standard), Ra ≤ 0.5 μm for ultra‑hygienic applications

• Cleanability (CIP/SIP): No dead legs or cavities; 15‑30° recommended installation angle for complete drainage

• Connections: Hygienic clamp (Tri‑Clamp), SMS, or DIN – replacing traditional flanges in product contact areas
