FLCOS

Rupture Disk & Sensor Combination

The Oseco FLCOS is a combination rupture disk and sensor that is easy to install and fits between standard ANSI flanges. The uni-body construction makes the FLCOS the most rugged and dependable disk/sensor on the market today.

The FLCOS is suggested for applications in which the normal operating pressure does not exceed 50% of the rated burst pressure.

This combination disk/sensor has a standard 316 Stainless Steel center membrane that controls the burst pressure and is also the sensor circuit. (Consult the Oseco factory for other metals).

The stainless steel center membrane is lined on both sides with a Fluoropolymer liner to form a corrosion-resistant anti-stick barrier. Klingersil C-4401 ring gaskets are standard and attached to both sides to form the completed assembly.

• No Special Holders Required
  Fits between standard 150# ANSI RF flanges.
  
  
• 2 Products in 1
  Patented design eliminates the need for separate disk & sensor.
  
  
• Bi-Directional
  Same burst pressure in either direction. Cannot be installed incorrectly.
• Low Pressure Relief
  Oseco exclusive.
  
  
• Corrosion-resistant Fluoropolymer in Contact with All Process Media
  Isolates rupture disk from corrosion. Cost savings due to combined rupture disk/sensor.
