• Compact Design

• Improved Self Flushing Design

• Improved Air-Flow

• Surge Protection

• Enhanced Wear Resistance

• Protect Pipeline From Collapse Due To Vacuum

• Column Separation Protection

• Durable, Reliable and Proven Design

• Low Maintenance Construction - 316L SS

• Efficient, Effective and High Value - Best in Class!

• Patented Design Features

The 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.
