Leybold Valve Assembly, Part# 35020158 – vacstellar

Inside a vacuum pump, several parts need to work together perfectly. Valves are essential for controlling the flow of air and gas. This product is a complete valve assembly from Leybold.

Think of it as a pre-built unit. It contains all the necessary internal pieces—like plates, springs, and seals—housed together. This makes maintenance much simpler. Instead of replacing many small, individual parts, you can install this one complete assembly.

A properly functioning valve is crucial. It helps your pump create and maintain a strong vacuum efficiently. If a valve in your pump is worn out or damaged, performance will suffer. The pump might struggle to reach the right pressure or work harder than it should.

Replacing the entire assembly is often the most reliable repair method. It ensures all the internal components are new and work together seamlessly. This restores proper function and helps your pump run smoothly again.

This is an official Leybold part (35020158). It’s made to meet the original equipment specifications for fit and performance.
