Vacume Brakers – SV Series

Chemline SV Series vacuum breaker valves are designed as one way valves, opening only when process pressure drops in order to allow air/gas into the process. Its operation is simple as the ball is held at the top of the vertically mounted valve by a coated spring.

Once process pressure drops, the ball comes off the top seal and allows air/gas into the process. When the vacuum has been broken, the spring pushes the ball against the top seal to close the valve and isolate the process.
