Vent-Tech Model WTW
Redesigned for Unmatched Innovation and Performance
The Vent-Tech Model WTW Water Valve is an advanced air release and vacuum break solution engineered to seal reliably at 3 psi hydraulic head. Built on over 13 years of manufacturing expertise, the WTW improves upon the proven performance of the Model WTR with enhanced flow dynamics and surge protection capabilities.
Optimized for clean water systems where pressure consistently exceeds 5 psi, the WTW delivers superior efficiency, durability, and low-maintenance operation. Now available in sizes up to 16 inches, the Model WTW is the trusted choice for engineers demanding high performance under demanding conditions.
- Original flat float design with over 30 performance improvements
- Built-in protection against water hammer and surge
- Optimized for low-pressure sealing at less than 3 psi
- Full port vacuum relief for efficient flow management
- Pressurized air release enhances system reliability and safety
- Low-pressure optimization ensures effective sealing in sensitive applications
- Advanced design improvements deliver superior performance and durability
- Reliable protection reduces system risks and ensures long-term stability

Vent-Tech Valve Series Configurations
SERIES-C Combination Air Valves
Note to Engineer
Shall be four (4) function valves designed to:
- Exhaust large quantities of air at start-up during the filling of a pipeline system.
- Prevent the development of hydraulic transients (surge control) during start-up and pressure surges and shall operate automatically.
- Release accumulated air in a pipeline system while the system is operational and under pressure.
- Open and admit large quantities of air into the pipeline system during draining or if negative pipeline pressure occurs.
SERIES-B Biased Combination Air Valves
Note to Engineer
Shall be four (4) function valves designed to:
- Exhaust controlled quantities of air at start-up during the filling of a pipeline system.
- Prevent the development of hydraulic transients (surge control) during start-up and pressure surges and shall operate automatically.
- Release accumulated air in a pipeline system while the system is operational and under pressure.
- Open and admit large quantities of air into the pipeline system during draining or if negative pipeline pressure occurs.
SERIES-V Vacuum-Restrictive Air Valves:
Note to Engineer
Shall be four (4) function valves designed to:
- Exhaust large quantities of air at start-up during the filling of a pipeline system.
