Model - QOC

Easy Access  | Pressure Warning Device |  Convenient
QUICK OPENING CLOSURES have no blind flanges, a welcome benefit when frequent access to vessels is required.

One person with standard wrenches can open and close even the largest Quick Opening Closure. Opening is as simple as venting the pressure, checking the Pressure Warning Device (PWD), removing safety bolts and turning draw bolts to disengage the two piece yoke. The head then swings open easily. A trolley system, which bears the weight of the yoke, assures the same quick, convenient operation on larger closures.

Fully tested and performance verified under extreme pressures.
