Instrumentation Pressure Regulators TS311

The TS311 is a two-stage piston-sensed pressure regulator with solid disk seat design and is ideal for Hydrogen applications where embrittlement of metal diaphragms can lead to failure. The large piston sensed elements provide stable pressure control under decaying inlet pressure conditions and have the option of spring energised seals to cope with extreme low temperature conditions. The first stage of the regulator is preset at the factory and locked to prevent alteration. The second stage of the regulator, with a PCTFE seat as standard, can be adjusted by the user between various outlet pressures within the range.
