Every valve is factory tested with nitrogen gas @1,000 psig (68.9 barg) for leakage to a maximum allowable leak rate of 0.1 SCCM at
seat. Hydraulic shell test is optionally performed at 1.5 times the working pressure to a requirement of no detectable leakage with
a liquid leak detector.
Every valve is cleaned and packaged in accordance with DK-Lok cleaning standard DC-01. Special cleaning and packaging in accordance
with DK-Lok DC-11 ensures compliance with product cleaning of ASTM G93 Level C is available on request for valves with PCTFE and
PTFE seats.
The selection of a valve for any application or system design must be considered to ensure safe performance. Valve Function, valve rating, material
compatibility, proper installation, operation and maintenance retain the sole responsibility of the system designer and the user. DK-Lok accepts no
liability for any improper selection, installation, operation or maintenance.
