Product Summary

High-Integrity Sealing for Negative Pressure Environments.

The Manual Vacuum Valve is a specialized ball valve designed to hold a vacuum without leakage. Unlike standard valves that are designed to keep pressure in, this 316 Stainless Steel valve is engineered with specialized packing and seals to keep air out, ensuring the integrity of your vacuum chamber or suction line.

Product Description

In vacuum applications, even a microscopic leak can compromise a process. This valve features high-precision machining and enhanced stem sealing to withstand negative pressure. It operates with a standard quarter-turn handle but provides the tightness required for low-to-medium vacuum ranges. It is the gatekeeper for vacuum pumps and chambers.
