Frequently Asked Questions

What is a Isolation Valve?

A valve whose primary purpose is to fully open or fully close to isolate equipment or pipe sections for maintenance or emergencies. Must achieve tight shutoff (ANSI/FCI 70-2 Class IV, V, or VI). Ball, gate, and butterfly valves are common isolation types.

What is a Isolation Valve used for?

Isolation 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 Isolation Valves certified to API 6D, ASME B16.34, and other applicable standards.

How do I select the right Isolation Valve for my application?

Selecting the correct Isolation 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).
