The RKE86A wafer non-return valve is also suitable as a vacuum breaker valve to prevent unwanted backflow and protect systems against negative pressure. The vacuum vent valve is suitable for installation between flanges PN10-40 and ASME Class 125/150/300 and has a short face to face length acc. to EN 558, Series 49. The metal-seated valve has the body made of stainless steel 1.4408 and the valve disc as well as the spring are made of stainless steel 1.4571.

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
