The plant operator replaced traditional globe style valves in this steam facility – without making any other changes to the plant – with sliding gate valves. Then the temperature control parameters were readjusted and the resulting steam consumption measured with the following remarkable results. Afterwards, the steam consumption fell in the

60 degree line by 200 kg/h, or 36 %,

65 degree line by 200 kg/h, or 25 % and

70 degree line by 150 kg/h, or 17 %.

The investment in the sliding gate valves had payed off within a matter of a few months.

Palm oil producer Palmaju Edible Oil saves 5 tons of steam per day

Besides the advantages that sliding gate valves can bring to systems, they are also easy to automate. The potential savings that can be achieved from a sliding gate valve incorporating an intelligent positioner are impressively documented by the operator of a palm oil plant, Palmaju Edible Oil, in Johor, Malaysia. By using a small sliding gate valve with a nominal size of DN32 with an electro-pneumatic positioner instead of a self acting pressure regulator, Palmaju Edible Oil was able to reduce the steam consumption by 5 tons per day. Based on the energy generating costs in Malaysia the savings potential amounts to over 25,000 euros per year for the plant operator by using this single valve.
