The primary function of a blowdown valve is to control the concentrations of suspended & total dissolved solids (tds) in the boiler. Boiler blowdown is a severe service application which results in rapid erosion and wearing out of conventional valves.
Continuous blowdown (cbd) valves are designed to operate in continuous open position by releasing water continuously through a blowdown tap near the boiler water surface, thereby maintaining the tds level in the boiler drum. Inditech continuous blowdown valve is an angle type valve with a needle shaped trim in a venturi diffuser. The venturi diffuser provides sufficient area for the high velocity flashing water, thereby avoiding choked flow.
