Aohoy's Sampling & Diaphragm Valve combines the functions of sampling and diaphragm valve. The valve body is made of high-quality stainless steel with strong corrosion resistance. The diaphragm is made of non-toxic, sanitary materials with good sealing performance, which can effectively prevent medium leakage and contamination.
The structure design is compact, the flow channel is smooth, and it is easy to clean. It is suitable for industries such as food, pharmaceuticals, and chemicals that have strict requirements on hygiene and medium purity.
Zero-Leakage Assurance via 100% Pressure Testing Every single valve undergoes rigorous air-tightness and hydraulic pressure testing before leaving our factory—we never rely on random sampling. We use FDA-compliant EPDM and PTFE seals designed for high-cycle durability, ensuring stable operation even in intensive processing environments.
Hygienic Design for Contamination Control Our valves feature a "Full Bore" and "Dead-leg Free" internal structure that eliminates fluid retention areas where bacteria can grow. This precision-engineered flow path maximizes CIP/SIP cleaning efficiency, safeguarding your product purity in food and pharmaceutical applications.
Complete Material Traceability (EN 10204 3.1) Quality you can trace. All valve bodies are laser-marked with a unique heat number. We provide full Material Test Certificates (MTC 3.1) with every shipment, ensuring complete traceability from the raw steel ingot to the finished valve.
Low-Cost Maintenance & Serviceability Designed for the real world, our valves feature an easy-disassembly structure that requires no special tools for seal replacement. We maintain a permanent stock of standard seal kits, minimizing your downtime and maintenance costs.
