This post was last edited by leo_0088 on 2017-5-18 at 11:18. What does HM mean on the body of a direct-through hemispherical valve, and what do numbers like 8856 below it mean? Seeking advice

HM is a pneumatic sleeve control valve.

How could it be pneumatic? Valves on-site, right?

H means manual, and M means switch; in other words, only OPEN and CLOSE are available for regulating flow
