ABSTRACT:
A valve is provided for precisely controlling fluid flow at low flow rates and simultaneously filtering said fluid. The valve employs a resilient porous filtering medium interposed in the flow path and capable of undergoing adjustable compression by means of a threaded shaft associated with an external handle. When the filtering medium is compressed, it provides greater occlusion of the flow path, thereby diminishing flow rate through the valve. The valve is readily dismantled to facilitate cleaning or replacement of the filtering medium.
