Pyrolysis can be described as the thermal decomposition of homogeneous waste in the absence of oxygen, ‘flashing’ organic waste into a syngas at elevated temperatures. Our high integrity knife gate valve technology was selected for use on the front end bulk handling system, for high integrity isolation, of the pyrolysis kiln. This DN700 ORBINOX ‘TL’ series through conduit knife gate valve has been fitted with a double acting pneumatic actuator. Our PNEUTON™ engineering team customised the control logic to meet the projects specifications. Our PneuLINK™ linear-to-rotary integrated control platform was selected as best practice. An external discrete volt free contact has been back-wired into the enclosure as part of an interlock system. The integral G1/4″ 5/2 mono-stable solenoid valve pilots 2-off 1:1 ratio filter-volume boosters to meet the specified operating time.
