International Valve Marketing has engineered, designed, developed and introduced to the US market a new Combination Water and Sewage Air Relief Valve. This patent pending air valve offers significant advancements in multi-orifice air relief valve technology, and are now available in Vent-Tech’s exclusive and patent pending product line. International Valve Marketing, LLC. is a leader in air valve technology, innovation and customer service.

Based on more than a decade of marketing experience, we have redefined the technology to give you “Made in America” products that outperform the competition. We have reconfigured our distribution network and engaged the input of international fluid-dynamics and the latest flow simulation technology. Vent-Tech valves provide up to 40% greater venting capacity and offer a dynamic surge-control capability responsive to line pressure. A float design to accommodate high temperature spikes at sonic air velocities and debris control with minimal wear are standard features of Vent-Tech air valves. We have incorporated perforated metal screens throughout the product line to minimize the restrictive effects of bio-fouling on airflow performance. These features have been specifically targeted to provide the benefits of reduced energy loss, less frequent valve replacement, lower maintenance costs, and longer operating life. In many cases, the Vent-Tech design will allow for a valve to be downsized – further reducing your installed costs. We bring you these new features because you asked for them. We listened. We are still listening. Feel free to contact us for technical information or application support

The Vent-Tech Model WTR clean water valve combines thirteen years of manufacturing experience with advanced Patent Pending flow designs. The Model WTR was engineered to expand and improve the technological advances of the flat float air/vacuum valve.

Model SZG – Zero Pressure Sewage Valve

The Market Leader in Zero Pressure Flat Float Valve Designs!

• Improved Air-Flow
• Enhanced Wear Resistance
• Zero psi Minimum Sealing
• Protect Pipeline From Collapse Due To Vacuum
• Maximize The Capacity of the Pipeline
• Surge Protection
• Column Separation Protection
• Durable, Reliable and Proven Design
• Low Maintenance Stainless Steel Construction
• Efficient, Effective and High Value – Best in Class!
• Preferred Valve of Top Civil Engineering Firms

The Vent-Tech model SZG sewer valves are air release and vacuum break valves designed to provide surge protection and seal at zero hydraulic head (i.e. no reliance on a minimum pipeline pressure to achieve seal). If the HGL is expected to be consistently maintained above 3 psi then use a Model SWG valve, otherwise we recommend specifying the SZG.
