Certified to ISO 9001, Valvtechnologies is the leading manufacturer of metal seated ball valves. At Valvtechnologies, we won't ship a valve unless it shuts off completely: 100%. We test every valve we make according to ANSI procedures, but we toughen the standards. And we attach our signed and witnessed test report to every valve. With that kind of quality control, Valvtechnologies valves last longer and reduce maintenance cost.
