Why you Cun Expect longer, Trouble-Free Service The choice of mtrtala used in the R PsC Rising Stem Bronze Gate has a lot to do with its fine service record. The body is cast of high test bronze in our own foundry, the stem is high tensile rolled bronze, while the solid wedge and seat rings ore nickel-alloy. The design is important, too. The union bonnet adds strength andwon't distort thevalve body or threadswhen it is removed. Fluids don't come directly in contact with the operating threads and the rising stem shows position of the wedge. It's easy to disassemble this valve where frequent cleaning Is necessary.

Chain Beil Co, Milwaukee 1, tflicoarin In the almost quarter century rhar we have been in business, we hare been called upon lo develop and produce many highly specialised types of expansion joints. None, however, have been more spec tacular rhan the 109-inch joints '.recently developed for use in test ing equipment for aircraft engine prototypes. These low pressure joint* were designed with o hun dred internal lie bars, which per mit (be joints to absorb (he lateral deflection between a long exhaust .header, operating at 690* F. and a series of large gas coolers, without tbc need for heavy anchors. Eight of these joints are now in service in a classified defense project. This is just another exomple of how Zalica engineers, with the experience gained from specializ ing in one product--expansion joints, are able to successfully and economically solve ihe most dif ficult problems confronting this type of industry. But this Is not all--we regularly manufacture complete line of expansion joints capable of service in virtually any type of expansion application. These joints are avail able In diameters from 3 inches to 30 feet for temperatures from sub zero to ldOO*F.... for pressures from vacuum to 3OO psi in stand ard designs and up to 2,000 psi in special detigns. for fuff details regarding your ex pansion joint problems or require ments, just get in touch with us.
