Vacuum Sampling Valves

Vacuum Sampling Valves

Our Vacuum Sampling Valves are precision-engineered borosilicate glass valves designed for safe, controlled sampling from systems operating under vacuum conditions. These valves allow operators to extract accurate, contamination-free samples from glass reactors, vessels, and pipelines without breaking vacuum or disturbing process stability.

Manufactured from Borosilicate Glass 3.3 and fitted with high-integrity PTFE seals, vacuum sampling valves deliver exceptional chemical resistance, leak-tight performance, and long-term reliability in chemical, pharmaceutical, and laboratory vacuum processes.

How Vacuum Sampling Valves Work – Step-by-Step Process

1. System Under Vacuum – Reactor or vessel operates at sub-atmospheric pressure
2. Valve in Sealed Position – PTFE seal maintains vacuum integrity
3. Controlled Valve Opening – Operator opens valve gradually
4. Vacuum-Driven Inlet Flow – Sample is gently drawn into the sampling line
5. Sample Collection – Representative sample collected without air ingress
6. Secure Valve Closure – Valve reseats, restoring full vacuum conditions

• No vacuum break
• No air contamination
• Stable process conditions maintained

Frequently Asked Questions (FAQ) – Vacuum Sampling Valves

Q1. What is a Vacuum Sampling Valve used for?

A Vacuum Sampling Valve is used to safely withdraw process samples from reactors or vessels operating under vacuum conditions without breaking the vacuum or allowing air ingress. It ensures accurate, contamination-free sampling during live operations.

Q2. Can sampling be done without breaking the vacuum?

Yes. Our vacuum sampling valves are designed to maintain full vacuum integrity during sampling. The PTFE sealing system prevents air leakage, ensuring stable process conditions throughout the operation.

Q3. What materials are used in your Vacuum Sampling Valves?

Our valves are manufactured from Borosilicate Glass 3.3, known for its:

• High chemical resistance
• Excellent thermal stability
• Superior mechanical strength

The sealing components are made from high-purity PTFE for leak-proof performance.
