The TODO® Safety Pressure Tight Cap was designed in cooperation with the major European chemical companies and other interested parties.
The aim was to design a sealing cap system that would reduce pressure behind the cap if all other upstream closures had failed, thus protecting the operator from harm.
The cap system also alerts the operator to the existence of pressure behind the cap thus giving warning of potential upstream valve failure.
TODO Safety Pressure Tight Caps (PTC) are available in the following formats:
2" (DN50), 3" (DN80), 4" (DN100)
