The PCM Modulating Control and new higher pressure HPCM Modulating Control offer a variety of features. It opens in proportion to the overpressure to minimise fugitive emissions and product loss as well as to reduce noise. The PCM also reduces the shock loads to vessels and piping systems due to valve actuation. Its set pressure is not affected by constant
or variable back-pressure. In addition, he Modulating Controls can be directly interchanged with our snap acting control in the field for both cost and time savings.
