Vacuum breaker VBS21 1/2" is designed for steam systems and industrial process applications where vacuum formation must be controlled and condensate drainage supported. When a vacuum develops, the valve allows air to enter the system, helping protect pipework, heat exchangers and vessels from potential vacuum damage. Stainless steel construction, featuring a 1.4305 body and an AISI 440 C valve ball, provides a robust solution for industrial service. The 1/2" BSP female system connection and separate 1/8" BSP female air inlet allow integration into suitable installations. Operating limits must be observed in accordance with the datasheet.*Successor model to the VB14 and VB21
