Dover OPW CIVACON T196SV-CV Instructions for use

T196SV-CV Crude Vapor Recovery Vent
Instruction & Maintenance Manual
Product Description
Civacon’s T196SV-CV Crude Oil Vent is manufactured to withstand high pressure
crude applications. It will open against 35 psi tank pressure. The unique
patent pending dual stage poppet will relieve tank pressure during the 1st stage,
allowing for optimal venting during the 2nd stage action. It is designed and
tested to take the punishment of crude oil transportation at temperatures from
-40oF to 220oF (-40oC to 104oC). A new cap design threads into the top of the
vent which allows for a better seal and eliminates the snap ring on top.

Exhaust Port Caution: Exhaust port must not be allowed to be sub-merged in
water and port must remain free of obstructions. The fitting shall be installed in a
horizontal or a decreasing angle as provide from the Civacon factory. The exhaust
tube opening should not be allowed to rest on the manhole cover. The tube should
be overhanging the man-hole assembly.
Alternate exhaust configurations: If you believe that the exhaust tube may be
submerged in water at times due to inadequate drainage we recommend daisy
chaining all exhaust ports together and locate the exiting tube where it will not
be restricted (i.e. midway down the back of the tank).
Lubricant to be applied to these areas of
the valve: Note: All O-rings to also be
lubricated. (recommended lubricant,
