This female thread gauge valve is a micro-sized instrument valve whose internal thread connection is machined on the line side for direct mounting on small-diameter threaded piping. The body is made from 304/316 stainless steel with a total structural length of about 12 mm, and the ceramic stem and seat give a response sensitivity of 0.01 MPa, so the valve passes very small pressure changes through to the gauge without throttling. The compact structure suits experimental benches and precision instruments, and the small internal volume keeps dead space low in clean fluid systems.
At this size, the valve is only as accurate as its machining, and the buyer's real concern is whether the tiny thread and bore are cut consistently. We produce the internal thread and the ceramic seat in the same setup so the flow path stays concentric, which is what keeps the 0.01 MPa sensitivity repeatable from unit to unit. For laboratory customers who need a slightly different thread or a cleaner internal volume, the configuration is adjusted from the drawing and the finished valve is leak-tested before packing, so the delivered lot behaves like a single batch.

Applications
- Laboratory benches: the micro body and ceramic seat control small flows where a full-size valve would over-range the instrument.
- Precision instruments: the 0.01 MPa sensitivity passes fine pressure changes without throttling the reading.
- Clean fluid systems: the small internal volume reduces dead space where media could stagnate between runs.
Customization
Thread size, bore and body length can be confirmed from drawings or samples. OEM/ODM production with fixed micro-configurations for repeat orders is supported.
Packaging & Transportation
Micro valves are packed in moisture-proof cartons with internal cushioning; bulk orders use wooden crates. We support EXW, FOB, CIF, CFR, DAP and DDP.
