ABSTRACT:
A valve for the control of corrosive fluids is disclosed which includes a spring returned valve spool in a valve housing, the valve being manually movable by actuation of an exteriorly accessible handle, the valve spool being connected to and movable with a pipe for dispensing, the handle being removably carried on the valve housing, the valve housing having separable portions for access to the interior, the valve spool having a central passageway communicating with the dispensing pipe and having spaced packings movable in a bore, the spool in one position having one packing positioned to permit access of fluid to the central passageway while the other packing prevents access of fluid therebeyond and protects other components associated with the valve spool.
Provisions are also made for locking the spool valve to prevent unintended fluid delivery.
