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.

Valve for corrosive fluids

A powder sprayer is described having a barrel or cylinder of synthetic plastic material with an interior baffle cup preferably adhesively secured in the cylinder and closed by a cup closure plate, a check valve being carried therein, the cup bounding a powder chamber and having an air delivery tube, preferably slitted, extending thereinto. The air delivery tube has a threaded end for engagement by a nut rotatable by a manually accessible knob pivotally mounted on an end closure removably sealed to the barrel. The end closure carries a powder delivery tube extending therethrough with its inner end closed and with slits for receiving powder to be delivered through the outer end of the powder delivery tube. The outer end of the powder delivery tube is adapted for attachment of extension tubes and fittings for various types of powder delivery. The powder chamber can be readily refilled by turning the knob and removing the end closure for that purpose. The cylinder at the inlet end has an inlet end collar detachably secured to the cylinder with a hollow tubular piston or plunger also of synthetic plastic material, closed at its inner end and with spaced plates for reception therebetween of a gland or strip packing which serves as an inlet valve. The cap closure plate and inlet end collar bound a pumping chamber within which the tubular plunger is longitudinally movable. The tubular plunger provides a space for storage of extension tubes and nozzle tips and has a resilient closure cap frictionally engaged therewith.
