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.

Sprinkler valve module with reciprocating valve seat

A sprinkler includes an outer case and a riser mounted for reciprocation within the case. The riser supports a nozzle, an impeller, and a drive linkage connecting the nozzle and the impeller. A diaphragm valve is mounted in outer case beneath the riser and includes a valve member vertically reciprocable within a valve support housing to engage and disengage a valve seat. The valve seat can reciprocate relative to the valve support housing to reduce mechanical loading.
