Explosion-proof solenoid actuated pressure relief valves, with unloading and pressure selection compliant with ATEX, IECEx, INMETRO, PESO
RQM*K*-P
DESCRIPTION
RQM3K*- P RQM5K*- P and RQM7K*- P are explosion proof, solenoid actuated pressure relief valves, with unloading and pressure selection. They are suitable for flowrates up to 500 l/min, for subplate mounting.
They are compliant with ATEX, IECEx, INMETRO or PESO 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.
Five versions are available, for the discarge of the entire flow by a solenoid valve or for selection of up to 3 pressure values: the selection of the second and third pressure value is obtained by means of a pressure relief valve placed between the main stage and the solenoid valve. Ports for remote pilot supply of the valve and for pressure gauge are present.
The valves are available with DC solenoid or RAC solenoids to be feed with AC power supply. Rectifier bridge is built-in in the coil. Several connection types are available, metric or NPT type. Cable-glands are available.
