Factory Test

• Every V23 series plug valve is factory tested for shutoff at 600psig (41.3 bar).

Optional Downstream Vent

Vent to atmosphere when valve is closed

Optional O-ring material

PTFE-coated FKM is standard. Choose optional O-ring material for
fluid compatibility and system temperatures.

valve openO-ring material

O-ring Designator

PTFE-coated Buna-NEB

Standard PTFE-coated FKM

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.
