For almost 100 years, Cash Acme has designed and manufactured water pressure, thermostatic, and temperature valves. In 1893, a young engineer named A.W. Cash was challenged to design valves for U.S. Navy submarines. With the unforgiving ocean as his testing ground, his new valves would require unprecedented levels of performance, reliability and dependability. When he later started the Cash Valve Manufacturing Company, those same standards became its foundation and they remain at the heart of today?s Cash Acme.
