Busch Air Vent Valve Part# 543138026 – vacstellar

Description

For reliable performance from your Busch R5 vacuum pump, you need parts that manage pressure perfectly. This Busch Air Vent Valve (Part# 543138026) is made for that job. It fits the R5 RA 0100 D and RA 0160 D models. 

Think of this valve as a smart safety release for your vacuum pump. Its main job is to control the flow of air in and out of the pump’s system at specific times.

During start-up and shutdown, pressure inside the pump can change quickly. This valve opens and closes to balance that pressure gently. This prevents strain on the pump’s motor and internal parts.
