<p>A pressure operated normally closed control valve operates to open at a predetermined pressure between the system minimum and maximum pressures to open the valve and allow the discharge of condensate from the system which has a source of pressure to provide a minimum and a maximum pressure. The system is subject to the formation of condensate. There is an inline filter at the inlet end of the valve and a discharge nozzle at the outlet end of the valve. The entrance to the discharge nozzle may also have a filter. The assembly can also be arranged so that the control valve is normally open and operates to open at a predetermined pressure at or below the system minimum pressure whereby condensate is removed, and to close the valve and prevent the discharge of condensate from the system when the pressure falls below the predetermined pressure.</p> |
