Ci Cylinder Orifice Item numbers covered by this datasheet 305733 Ci Cyl Orifice
General The Ci Cylinder orifice is used to limit the orifice of a single cylinder in a system. This version is intended for use in systems with Ci IV8 valve(s). Typical use could be when an extended discharge is desired.

Installation 1. The orifice size is verified with a calibrated calibre. 2. The o-ring is lubricated. 3. The orifice is inserted into the Hand Wheel Valve (HWV) with the Ø8 “tube” protruding from the HWV, see next page (this is to ensure that it can easily be identified and possibly removed in the future). 4. The discharge valve (Ci IV8) is carefully fitted onto the HWV as usual. 5. The discharge cylinder must be marked with a permanent label with the text “ORIFICE”. 6. Do NOT mount the actuator on this discharge valve if using back pressure or PA line activation! Do not rely on actuators mounted on this valve to activate anything else than this valve!
