VT86 Series Trunnion Ball Valves
VT86 Series Pressure Rating up to 413bar (6000 psig)
VTH86 Series pressure Rating up to 689bar (10 000psig)
VCT86 Series CNG/NGV Valves

Catalog No VT86-4
March 2010

Features● The Trunnion ball valve is featured by blowout-proof design withcylindrical extensions at the top and bottom of the ball.
● The trunnion prevents the ball from shifting and permits the ball torotate on a vertical axis.
● Integral ball stem machined from single piece of bar stock eliminates

the backlash during handle actuation.
● Panel mounting nut is standard permitting valve to panel or actuator.

Factory Test
Every valve is factory tested with nitrogen gas at 68.9bar (1000psig) 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 liquidleak detector.

Cleaning and Packaging
Every valve is cleaned and packaged in accordance with DK-LOK cleaning standard DC-01. Special cleaning and packaging inaccordance with DK-LOK standard DC-11 ensures compliance with product cleaning of ASTM G93 Level C is available on request forvalves with PCTFE and PTFE seats.

CNG/NGV Certifications
VCT86 and VCT863 Series valve provides leak-tight integrity in both low and high pressure systems in CNG and NGV applications.
Valves with PAI seat and HNBR O-ring are compatible with CNG fluid.

OptionsVT86 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).

DVDownstream Vent
Ordering designator - DV

Upstream Vent
Ordering designator - UVWhen 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.

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.

UVService Kit
VCT863 Series Ball Valve

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.

Maintenance Instructions

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 thesystem designer and the user. Dk Tech accepts no liability for any improper selection, installation, operation or maintenance.
