• The Trunnion ball valve is featured by blowout-proof design
with cylindrical extensions at the top and bottom of the ball.
• The trunnion prevents the ball from shifting and permits the
ball to rotate 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.
Every valve is factory testedwith nitrogen gas at 68.9bar (1,000psig) for leakage to amaximumallowable 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 ac-
cordance with DK-Lok standard DC-11 ensures compliance with product cleaning of ASTM G93 Level C is available on request for
valves with PCTFE and PTFE seats.
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.

• Valves that have not been actuated for a period of time may
have a higher initial actuation torque.
• VT86 Series ball valves are designed to control fluid in full open
and full closed position.
