Abstract
A clean in place or sterilize in place valve includes both over pressure and vacuum protection. The apparatus can be remotely operated and monitored to assure that the valve did or will function correctly. The valve housing has a bore that communicates with a vessel. The bore is valved with separately movable pressure valving and vacuum valving members, each separately adjustably set at desired positive/negative pressure valve settings. The vacuum release can be operated independently of the pressure release.
