Micro Valve with Union
What is a Micro Valve with Union?
A Dairy Micro Valve with Union is a compact, hygienic valve designed for precision control in small-bore sanitary pipelines. It is ideal for applications requiring minimal flow regulation or shut-off in confined spaces. The union-type connections allow easy disassembly for cleaning and maintenance, essential in industries with strict hygiene standards.
Asaid Steel Industries is a trusted supplier of Dairy Micro Valves with Unions, offering durable, corrosion-resistant valves made from SS 304 or SS 316L, designed to meet stringent hygienic standards.

Do you have questions?
It is used for low-flow applications such as sampling, dosing, and precise shut-off in sanitary systems.
Yes. With compatible seal materials, it supports CIP and SIP cleaning up to 140°C.
Union-type valves offer robust threaded assembly and a tighter seal, preferred for higher mechanical stability in sanitary pipelines.
We offer dairy micro valves from ½” to 1.5” with SMS, DIN, RJT, or IDF union ends.
