Micro flow control valve is designed for small flow regulation and development of small diameter control valve. Body with threaded connection, with a small size, light weight, installation, easy maintenance and so on. Adjust the non-clean media, it should be for its throttling gap small problem, pay attention to prevent the occurrence of blocking card phenomenon. It is suitable for liquid, steam and other media injection flow adjustment occasions.
