The D-26 & D-23 combination air valve features both an air release valve and an air & vacuum valve, incorporated into a single body. The D-26 & D-23 are specifically designed to operate with liquids carrying solid particles such as wastewater and effluents.
The combination air valve releases accumulated air (gas) from the system during operation under pressure and also discharges air (gas) during the filling or charging of the system. The valve also admits air into the system during drainage and at water column separation.
Conical body shape
Designed to maintain the maximum distance between the liquid and the sealing mechanism and still obtain minimum body length.
Independent spring-guided linkage
Allows free movement of the float and rod. Vibrations and movement of the lower float due to turbulence will not unseal the upper float mechanism.
Funnel-shaped lower body:
Designed to ensure that residue matter will fall back into the system and be carried away by the main pipe.
