Industrial gate valves
Industrial gate valves are used to isolate or control flow in industrial piping. Selection starts with the service medium, design pressure and temperature, DN, body and sealing materials—not with price alone. A replacement inquiry must also verify flange standard, face-to-face dimensions, stem clearance and maintenance access. State the applicable design and test standards, leakage criterion, actuator and required documentation. TAZ evaluates each inquiry against submitted project data; availability of a particular execution and compliance with a named standard are confirmed in the technical quotation and contractual documentation.
