Application

Sampling and analyzing systems, accurate and fine metering applications

Cleaning

UNILOK valves are free from machine oils, loose particles and grease throughout the close cleaning process.
The special cleaning for high purity application is available upon request.

Testing

Every valve is 100% factory tested with air and nitrogen at 1000psig(69bar) for leakage at the seat and packing. Each test is performed to a maximum allowable leak rate of 0.1scc/min.
VMTL series is tested at 100psig(7bar) differential pressure.

Important Notification

Proper installation, materials compatibility, operation and maintenance of these valves are the responsibility of the user. The total system design must be taken into consideration to ensure optimal performance and safety.
