Select the desired valve basic ordering number, options and body material.
PTFE-coated FKM is standard. Choose optional O-ring material for
fluid compatibility and system temperatures.
Optional vented plug and valve body provides system pressure release
to atmosphere when valve is closed.
•
This option reduces the maximum operation pressure to 150 psig (10.3 bar).
•
To order, use designator - VH. See how to order.

Safe Valve Selection
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 remain the sole responsibillty of
the system designer and the user. DK-Lok accepts no liability for any improper selection, installation, operation or maintenance.
