High-temperature back pressure regulator
By upgrading to an SS316 diaphragm and Kalrez O-ring, the operating temperature range can be extended to 300°C/527°F. Using a metal diaphragm also allows the pressure range to be increased to a maximum of 10,000 psig/689 bar(g). The standard PTFE/glass composite diaphragm can be used under conditions of low pressure up to 232°C (450°F), but considering the mechanical stress reduction of PTFE at high temperatures, the SS316 diaphragm is more practical for most high-temperature applications. In some applications, diaphragms made of Hastelloy C276 are also available.
