AS-Schneider, a leading valve manufacturer with branches in the Americas, offers the E Series Valves and Manifolds with sealing made of graphite, and suitable for use in high temperatures. The E series can be readily used up to 550 degrees Celsius – significantly more than required by the standards. The international standard EN 61518 / IEC 61518 describes the flange connection between the manifolds and the pressure transmitters. Here, the temperature limits of these connections are described, among other things: This is 80 degrees Celsius for PTFE sealing and 120 degrees Celsius for graphite sealing. The temperature limit of 120 degrees Celsius refers to the limits which are applicable for the transmitter. The limit for the flange connection itself can be dimensioned higher according to the pipeline standards.
