What is a Quarter-Turn Valve used for?
Quarter-Turn Valves are used in industrial piping systems for on-off isolation, flow control, or backflow prevention depending on the valve type. They are selected based on the process fluid, operating pressure and temperature, required shutoff class, and pipeline size. Vajra Industrial Solutions supplies Quarter-Turn Valves certified to API 6D, ASME B16.34, and other applicable standards.
How do I select the right Quarter-Turn Valve for my application?
Selecting the correct Quarter-Turn Valve requires specifying: (1) nominal pipe size (NPS/DN), (2) pressure class per ASME B16.34, (3) body and trim material based on fluid compatibility and temperature, (4) end connections (flanged RF/RTJ, butt-weld, socket-weld, or threaded), (5) required certifications (API 6D, ISO 9001, fire-safe API 607).
