Abstract
A valve module for removable installation inside the outer case of a sprinkler after removal of a riser with a nozzle turret normally mounted for reciprocation within the case. The module includes an upper valve support housing and a lower support basket removably connected to the valve support housing. A valve member is vertically reciprocable within the valve support housing to engage and disengage a valve seat in the support basket. The support basket is loosely connected to the valve support housing so that the valve seat can reciprocate relative to the valve support housing.
