Stainless steel vacuum breaker VB series

nitrile rubber

Prevent damage to equipment related to water supply lines and tanks. When pumping stops a large amount of air is drawn into the water supply line as a vacuum begins to form, preventing damage to equipment installed on the line. TLV adapted the VB3 for seawater use by producing a super duplex cast stainless steel version. Benefits and Features Large capacity in a compact body. (approx. 2000 Nm³/h with 0.03 MPa differential pressure) Combination of Free Float® and spring-loaded check valve allow for high sealing capability and durability The only moving parts are the hinge-less, lever-less free float and the center-guided check valve with coil spring support for long, trouble-free service life. Nitrile rubber ensures a tight seal for both valves. Free Float® rapid initial air vent allows for easy venting of initial air upon system startup* Suitable for use in salt water processes *While acting as an initial air vent, once the valve closes after discharging initial air, it will not open again, even if air accumulates inside the product, until internal pressure drops to near atmospheric pressure. Install an automatic air vent if air flows into the system during operation. Application Areas Applications where a large amount of air is necessary to be introduced to water supply lines to prevent a vacuum from forming, such as: Elevated Cooling Water Piping Coastal Seawater Supply
