— PRED3K* and PRE*K* are explosion-proof pressure relief valves with proportional control.
— They are compliant with ATEX, IECEx and INMETRO requirements and are suitable for use in potentially explosive atmospheres, for surface plants or mines.
—  A low temperature version (up to – 40 °C) is also available.
— The valves can be controlled directly by a current power supply or by means of an electronic control unit, to exploit valve performance to the full.
