Instrument Isolation Valves VCI Series 11F

Instrument Isolation Valves

Compact Wafer

The GVS 11F valve series is a wafer-style ball valve that either isolate an instrument or sit between two process flanges to isolate a line. It’s wafer-style construction makes for a lighter, more compact valve ideal for space and weight sensitive applications such as offshore platforms and other common isolation applications within the oil, gas, and chemical processing industries. The standard 11F valve is 2” x 1” x 2”, ANSI Class 150# and 300#, however this series can be designed and built to meet customers’ needs.

Technical Specifications

  • Sizes: 2" x 1" x 2" (Other sizes are available)

Series 11F Instrument Isolation Valve

Series 11F Instrument Isolation Valve

The Series 11F Instrument Isolation Valve is used in the food and beverage industry to provide compact, sanitary isolation for gauges, sensors, transmitters, and sampling devices without disrupting production. Its wafer-style design minimizes dead space, making it suitable for fermentation tanks, pasteurization systems, brewery and distillery process lines, and CIP/SIP loops, where cleanliness and hygiene are paramount. By allowing instruments to be safely removed, calibrated, or replaced while maintaining process integrity, the 11F valve supports continuous, contamination-free operation in high-purity food and beverage environments.

  • Fermentation Tanks: Allow safe isolation and removal of pressure or temperature sensors without interrupting fermentation.
  • Pasteurization Systems: Enable quick servicing of instrumentation while maintaining sanitary conditions in heat treatment lines.
  • Brewery and Distillery Process Lines: Provide clean, compact shut-off for gauges and meters in wort, mash, or distillation circuits.
  • CIP/SIP Loops: Isolate monitoring devices during cleaning or sterilization to protect sensitive instruments.
  • Beverage Filling Lines: Facilitate maintenance of flow meters or pressure transmitters without halting packaging operations.
  • Dairy Processing Equipment: Permit hygienic isolation of sensors in milk, cream, or yogurt processing lines to ensure compliance with food safety standards.
