Carbon dioxide cylinders are purpose designed seamless steel storage vessels manufactured to 84/525/EW6, and are independently tested.
              The height shown in table 1 is from the floor to the valve outlet connection. Cylinders are filled with maximum of 0.667 kg of CO2 per litre, and fitted with an internal syphon tube to ensure discharge of liquid agent only. Cylinders are marked with the gross weight and the net charge weight.

             A removable solenoid actuator may be fitted to the top of the pilot cylinder valve assembly to facilitate electrical actuation. The actuator is fitted with a knurled union nut connection which enables the unit to be oriented as required for electrical cable connection. Testing may be achieved by removing the actuator, applying a 24V dc signal, and observing the physical movement of the actuator pin to the latched energised position. Once actuated, the solenoid required manual reset before reconnecting to the valve.
