Quality & Testing

DTC threaded ball valves are manufactured under strict quality control and tested to ensure reliable performance. Every valve undergoes hydrostatic shell testing, air seat leak testing and torque verification before shipment. Our valves are designed and built to provide years of trouble-free service in demanding applications. We also offer custom options such as special materials, seat configurations and actuation packages to meet specific project requirements.
