Manually and mechanically operated valves

A manual valve is one operated by a person and a mechanical valve is operated by a machine interface. Manual and mechanical valves are strong, robust and reliable and so the units have multiple uses, which gives rise to their popularity. Manual and mechanical valves are of the spool type. In a spool valve, a profiled spool slides within a machined metal bore. As the spool moves in the bore, the profile of the spool either blocks or opens the connection between ports. There are a variety of operators, but the valve functions are those normally seen 3/2 and 5/2 ways
