BRAND : Douglas
BALANCED PRESSURE
The operating principle is based on the expansion and contraction of a temperature sensitive capsule. The elements are filled with a liquid whose saturation temperature is lower then that of water, at the same pressure. With subcooled condensate the elements contract. When steam is formed the pressure inside the element causes expansion to close the valve. .
MAIN FEATURES
Free air discharge. It withstands frost. Discharge of condensate slightly below steam temperature. It does not withstand waterhammer
