Product Overview
The Pfeiffer TVF 005 / PM Z01 135 J is a precision-engineered vacuum venting valve designed for controlled gas ballast and venting operations in high-vacuum systems. Manufactured by Pfeiffer Vacuum, a global leader in vacuum technology, this valve serves as a critical interface component for safely returning vacuum chambers to atmospheric pressure while preventing oil backstreaming and particulate contamination. The TVF 005 series operates as a solenoid-actuated, normally closed (NC) venting valve, ensuring fail-safe isolation of the vacuum environment when de-energized. The PM Z01 135 J designation refers to the specific electrical coil and connector configuration, optimized for 230 V AC operation. This valve is engineered for seamless integration with Pfeiffer rotary vane pumps, roots pumps, and turbo molecular pump systems, providing reliable, repeatable venting cycles essential for semiconductor processing, analytical instrumentation, and industrial coating applications.

Engineering Features & Advantages
- Precision Vacuum Control: The solenoid-actuated poppet design ensures rapid, repeatable venting cycles with minimal pressure overshoot, protecting sensitive vacuum gauges and chamber components from sudden pressure surges.
- Oil Backstreaming Prevention: When integrated with Pfeiffer rotary vane pumps, the TVF 005 valve introduces a controlled gas ballast during venting, effectively preventing hydrocarbon backstreaming into the vacuum chamber.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust coil insulation class F and mechanical life exceeding 1 million cycles.
- Direct Fit Replacement: Precision-manufactured to original PFEIFFER specifications for direct replacement, minimising downtime and eliminating fitment issues.
