<p>A pressure- balanced three way transfer valve (100) for controlling fluid flow into one or two fluid lines, particularly adapted for use in fluid systems to control flow through filter assemblies (101,102) that require servicing or replacement from time to time, permitting continued flow through one function while putting the other function off stream. The valve comprising in combination: a) a housing (1), b) a valve chamber (10), c) first, second and third fluid flow parts (2,3,4) and passages (5,6,7) in the housing (1), d) a first and a second valve member (20,21), e) a cam follower mechanism composed of the camshaft (26), cam wheel (70), the cam-following valve-actuating means, the reciprocable connecting rods (42,43) for moving the tubular valve members (20,21) between open and closed positions, f) a first and a second pressure-equalizing chamber (59).</p> |
