PVC Globe Valves
Homogenizing Mixer
PVC globe valves are now avail able in Va through 3-inch sizes, with either screwed or socket-weld ends. The valves are rated for 125 p.s.i. at 145° F. High chemical re sistance and mechanical strength arc features of the unplasticized poly (vinyl chloride) valves. Prices vary from $12.75 to $88, depending on size. Dept. IEC, Dorak Prod ucts Corp., 78 Pearl St., New York 4, Ν. Υ. 4
A complete line of mixers for lab oratory and production is now available. The Convertible Jet
Water Draw-off Valve Valves having two seats or valves mounted on the same stem are packless and not subject to freezing conditions. The inner valve is located well within the tank and is insulated by the air chamber be tween the inner and outer valve. Prices vary, depending on which of the four sizes is required. Dept. IEC, The Johnston and Jennings Co., 4700 W. Division St., Chicago 51, III. 5
