Cryogenic Butterfly Valves

Compact Isolation Solutions for LNG, Low-Temperature, and Process Service

Manufactured by Belgaum Aqua Valves Pvt Ltd – API & ISO Certified

Product Overview

AquaStream butterfly valves are offered in centric and high-performance eccentric designs for isolation duty across industrial and low-temperature applications. For cryogenic and LNG-related service, butterfly valves are typically selected where compact face-to-face dimensions, lower operating torque, and economical large-diameter isolation are important.

  • LNG storage and transfer systems
  • Low-temperature utility and process lines
  • Tank farm and terminal piping
  • Large-diameter isolation service
  • General industrial shutoff and automated on-off duty
Cryogenic Butterfly Valves

Standards & Compliance

Butterfly valves are produced to recognized international valve standards for design, pressure-temperature performance, inspection, and testing. Cryogenic suitability depends on service conditions, material selection, seat design, and extended bonnet requirements.

API 609 • ASME B16.34 • API 598 / ISO 5208 • BS 6364 (when specified) • ISO 9001 Quality System
