VT86 Series 2-Way Valve External Vent Options
A downstream or upstream vent option on VT86 Series 2-Way ball valve is available. The vent port is constructed on trunnion ball.
The vent port activates when the valve is in closed position. This option reduces the valve pressure rating to 34.4bar (500 psig).
For field assembly, service kit with a maintenance instruction is available. Service kit
contains wetted parts including trunnion ball, stem assembly and seat carrier assembly.
To order the service kit, prefix SK- to the valve series. i.e., SK-VCT863, SK-VTH863.
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.
Select applicable valve basic ordering number, options and body material designator listed below.
DownstreamVent
Ordering designator - DV
When a downstream vent valve in closed position,
shutoff at the upstream seat occurs. Downstream
system media flows into the vent hole and vents
out to atmosphere through the valve bottom.
UpstreamVent
Ordering designator - UV
When a upstream vent valve in closed position,
shutoff at the downstream seat occurs. Upstream
system media flows into the vent hole and vents
out to atmosphere through the valve bottom.
