Frequently Asked Questions

What is a Multi-Turn Valve?

A valve that requires multiple rotations of the handwheel or actuator to travel from fully open to fully closed. Includes gate, globe, diaphragm, and pinch valves. Opposite of quarter-turn valves (ball, butterfly, plug).

What is a Multi-Turn Valve used for?

Multi-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 Multi-Turn Valves certified to API 6D, ASME B16.34, and other applicable standards.

How do I select the right Multi-Turn Valve for my application?

Selecting the correct Multi-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).
