Plate Valve, Leybold, Trivac, S30A, D30A, D60A, Part# PL40164114 – vacstellar

This valve, part number PL40164114, is a small but mighty part inside your pump. Think of it like a tiny, one-way door. It opens to let air and gases flow out of the vacuum chamber. Then it snaps tightly shut to stop anything from flowing back in.

Over time, this constant opening and closing can cause wear. The valve may no longer seal perfectly. When that happens, air can leak back into the system. Your pump has to work much harder. You’ll notice a drop in performance and ultimate vacuum level.

Replacing this valve is a key part of pump maintenance. This is the official Leybold part. It is engineered to match your pump’s original specifications exactly. This ensures a perfect fit and the right sealing action.

Using a valve means your Trivac S30A, D30A, or D60A pump will work like new again. You’ll restore strong, reliable vacuum pressure. You’ll also help your pump run more efficiently and last longer.
