Vent Tech Model SDG – Sewage Short Valve

Vent-Tech Model SDG sewer valve is essentially a shorter version of the zero pressure sealing Model SZG combination air/vacuum relief valve. In low-pressure applications where clearance height is ample, specify the Model SZG valve, otherwise, we recommend specifying the Model SDG.
