Speakman Sentinel Mark II Pressure Balance Shower Valves have been engineered to deliver a complete and consistent shower experience. Featuring a pressure balancing and temperature regulating ceramic cartridge – this shower valve ensures water will be delivered without ever becoming scalding hot. Speakman pressure balance shower valves feature solid brass bodies with integral stops allowing for water shut off for valve maintenance. The valves also include temperature limit stops which allow the user to set a maximum temperature level. The valve is available in three connection types: sweat and thread connections, PEX F1960 cold-expansion inlet connections, or PEX F1807 crimp inlet connections. Speakman Sentinel Mark II Pressure Balance Shower Valves are ASSE 1016 certified to perform at flow rates as low as 1.75 GPM, making these valves ideal for use with shower heads from 2.5 to 2.0 GPM.
